TECHNICAL FIELD This invention relates to the connection of devices in automated transaction machines. Specifically this invention relates to a new method and system for connecting transaction services in automated transaction machines.
BACKGROUND ART Automated transaction machines are known in the prior art. Automated transaction machines are used to electronically carry out transfers representative of value. Automated transaction machines include for example, cash dispensers, ticket dispensers, scrip dispensers, gaming machines, Automated Teller Machines (ATMs) and other self service terminals. For purposes of convenience all such automated transaction machines will be referred to herein as ATMs unless otherwise specifically indicated.
ATMs may include various types of transaction function devices. These devices are operated to carry out transactions. Different types of ATMs include different types of devices. The different types of devices enable the ATM to carry out different types of transactions. For example, some types of ATMs include a depository for accepting deposits while other ATMs do not. Some ATMs have a “touch screen” while others have separate displays and input buttons. ATMs can also be fitted with devices such as cash and coin acceptors, statement printers, check validators, bill acceptors, thumb print readers and other types of devices, while other ATMs do not include such devices. ATMs also continue to incorporate improved or additional features. For example, printers are improved from black to color inks; cash acceptors are improved to work with both old and new styles of a twenty-dollar bill; and card readers are improved so they can work with magnetic stripe cards and smart cards.
As long as the basic functionality of a new device is the same as a device it replaces, the software code or drivers needed to communicate with the new device may also remain generally the same. Thus for example the application software for an ATM with a cash dispenser can issue a command to dispense cash as it has always done even after the cash dispenser is improved.
However, if the new device is so substantially changed relative to a device that it replaces so that it requires an updated driver, a service technician will be required to install a new device driver with the new device. As long as the new driver is backward compatible with the older driver, the ATM will continue to function generally as before.
Unfortunately installing new drivers can require more time than installing a new physical transaction function device in the ATM. Normally new drivers are installed from a floppy disk, CD ROM or other portable storage medium. A technician is required to access the computer that runs the ATM, and must replace the physical files of the old drivers with the new drivers. Even when user friendly setup programs or wizards are used to make this process easier, it requires a degree of specialized knowledge and expertise to update the ATM software driver correctly.
For example, a single type of device may have a different driver for each model and version that has been manufactured. Keeping track of the correct drivers and verifying that the correct driver is installed for a device, is a tedious endeavor. Furthermore it may not be obvious when a driver for “Model A” of a device is incorrectly used for “Model B”. Although 99% of the functionality of the device may work properly, an ATM with an incorrect driver may experience intermittent problems related to that 1% of incompatibility with the driver.
Tracking down these incompatibilities can consume a large amount of a technician's time. Consequently it would be desirable to streamline the updating of drivers to reduce the amount of time it takes to update a device and to reduce the chances of installing the incorrect driver for a new device.
A typical ATM application program not only communicates through an interactive user interface with input and output devices, but also controls the overall functionality of the devices in an ATM. Prior art ATMs generally require that the ATM be shut down when a new or additional device is installed. Prior art systems assume that individual devices that are configured for use in the ATM will remain available while the ATM is operating. However, if a device is disabled, prior art ATMs may not notice that the device is disabled until the ATM attempts to use the device, at which time an error is generated. Such an error usually results in the entire ATM or system being disabled until the device is reenabled or the ATM is manually reconfigured to know that the device is no longer available.
Consequently, changes to the configuration of an ATM require disabling the ATM for a period of time to remove, replace or add a device. This process can be time consuming and may result in lost business at the ATM. Consequently it would be desirable for an ATM to have the ability to detect when devices are present or not present and to automatically change configuration while continuing to operate.
Often functions of a device in an ATM are directly controlled responsive to inputs to a user interface. Individual devices often do not control the functionality of other devices. For example, when an ATM application program needs to lock or unlock a device which contains envelopes and also needs to enable a device which accepts deposit envelopes, the application must issue commands to both devices. This is the case even though both devices are related and are designed to operate at proximate times. Individual ATM transaction devices often do not communicate with each other. For example, a device for receiving deposit envelopes does not issue a command to the envelope holder to close the door to the holder when the deposit function is completed. The application program must generally include all the programing logic for coordinating the operation of multiple devices. The additional code required makes the application program more complex and more difficult to modify. Consequently it would be desirable for ATM devices to communicate directly with each other to facilitate the performance of coordinated activities by transaction function devices.
Prior art device drivers for devices in an ATM are often composed of low level functions for controlling the hardware. Programmers who create ATM software are generally required to have a high degree of knowledge about how a hardware device and device drivers are designed to work before the device can be incorporated into an ATM. This low level complexity often makes ATM application programs more complex and difficult to produce and reconfigure. Consequently it would be desirable to increase the efficiency of programmers who develop ATM software and to make device drivers easier for programmers to integrate into an ATM program without requiring the programmer to have an in-depth understanding of the low level hardware.
Many types of ATMs include an internal device bus to which transaction devices are attached. This device bus facilitates the communication between the application program and the individual devices. Such device buses are often proprietary and are designed to connect directly with the computer that controls the operation of the ATM. Such device buses limit the number of devices that can be attached to an ATM and limit the physical locations at which devices can be attached. Consequently, it would be desirable to have an ATM with a system for attaching devices that is not limited to the physical constraints of an internal bus.

Further objects of the present invention will be made apparent in the following Best Modes for Carrying Out Invention and the appended claims.
The foregoing objects are accomplished in one exemplary embodiment of the invention by an ATM that includes a network for attaching devices. This network serves as the communication link between the ATM application software operative in the main computer system of the ATM and the transaction function devices that comprise functional elements in the ATM. Examples of such transaction function devices include cash dispensers, cash acceptors, card readers, depositories, and printers. However, the present invention encompasses a new form of these transaction function devices called transaction services. Transaction services have properties of objects, similar to objects in object oriented programing languages such as C++ or Java®. Transaction services such as a print service, accept method calls remotely across the network for performing such functions as printing text or delivering a printed receipt. In addition services can issue events remotely in other services. For example a printer service can invoke an event in an application program when the printer service is out of paper. ATM application programs can also include elements of an object oriented service. In this way all components whether hardware or software have properties of objects that adhere to the same set of protocols. Thus the exemplary embodiment of the present invention is an ATM that is created by assembling service objects.
In the exemplary embodiment Sun Microsystems JINI™ defines the low level protocols used to configure transaction services on an ATM network. However, the present invention also encompasses other protocols such as Microsoft Universal Plug and Play™ that are operative to allow services in an ATM to automatically configure themselves on an ATM network and to communicate with each other with object method calls and events.
In an exemplary embodiment of the present invention, services include a computer processing unit and memory for running a Java® Virtual Machine (JVM). In addition services include a nonvolatile data store such as a disk or NVRAM for storing hardware-independent Java® software proxy objects. These Java® proxy objects replace prior art hardware-specific device drivers for controlling the physical hardware.
Prior art ATMs have an application software program that operates to cause the display of a graphical user interface, that receives inputs from input devices such as keypads and that controls the operation of the transaction devices such as a sheet dispenser. In the exemplary form of the present invention the application is itself a service. It interacts with other services such as a card reader service based on the JINI™ protocols. The application service is operative to acquire one or more service proxy objects for each service that must be controlled by the application. These service proxies originate from the individual services themselves and are used by the application service to remotely control services across the network. In this manner each service contains all the software necessary to control its underlying hardware functions. No longer is there a need for a service technician to install the correct drivers on the main computer of an ATM. Instead the correct service proxies are automatically updated from the service itself.
Upon connecting a new transaction service to a network in an ATM, the service is operative to locate a special service on the ATM's network called a lookup service. This lookup service is responsible for registering each service on the network and storing a copy of each services' service proxy. This process of registering a new service on the ATM network is defined by “discover” and “join” protocols. After registration, other programs or services that need to communicate with or control the functionality of a particular type of transaction service, contact the lookup service and download the appropriate service proxy. The service proxy in the exemplary embodiment is a Java® object that is run in the JVM of the calling service. This service proxy defines the methods and events necessary to communicate with a service across the network.
Because each service contains its own service proxy, when an old transaction service such as a cash dispenser is replaced with a new model, the service proxy for the new model is automatically installed and integrated in the ATM system. Consequently, the amount of time needed to update an ATM with newer services and the chances of installing incorrect drivers are reduced.
Because the transaction services each contain their own individual JVM, they are also operative to load the service proxies of other services which will enable them to communicate and control other services directly. This feature is useful for services that are designed to work in tandem. For example, in prior art ATMs the application program controls each device. However devices do not control the application program. In the exemplary embodiment of the present invention the application is a service. As such it has service proxies for each transaction service it has control over, such as a card reader service. However, because the application is also a service, the card reader may upload a proxy for the application that allows card reader to issue methods for controlling the application.
For example, when a debit or credit card is first inserted into a card reader, the card reader can issue an application method using the application proxy to awaken the application service and pass attributes representative of the numbers encoded on the card. Such service to service communication is more efficient and easier to program than having the application constantly monitor the card reader for card insertions as in prior art ATMs.
It is to be understood that services can be created that do not have the processing ability to run a JVM. For such services the protocols for configuring the service on the network may be programmed directly into the firmware of the service.
Another advantage of placing services on a network, is that services can be attached to an ATM at greater distances. For example, rather than placing all the transaction services inside a single ATM enclosure, multiple groups of services can be configured on the same network. For example a bank could have one large private or virtual private network with multiple sets of ATM services located throughout a city. Each of the groups of services represents a single ATM workstation with an application service and multiple other transaction services. A special host service on the network could route banking transaction messages between the multiple ATM workstations and an external host network.
An advantage of this system, compared to the prior art is that each service is an individually networked component, that can be easily replaced and updated dynamically. Further, each component of the ATM can be remotely monitored, taken off line to troubleshoot without interfering with other services in an ATM or other ATMs on the network.
Such dynamic connections have the advantage of allowing ATMs to connect to different types of services when needed. These on the fly connections make possible an alternative embodiment of the Jini enabled ATM in which the ATM is personal to an individual. This personal ATM can reside on any small portable computing device such as a notebook computer, cell phone, PDA, pager, or smart card. The personal nature of this embodiment allows an individual to store a plurality of their personal banking account information in a data store of the personal ATM. This alleviates the need to insert a banking card into the personal ATM to activate it. Instead, the personal ATM is inoperative until the personal password or other unique input of the owner of the personal ATM is entered and validated.
When a user of the personal ATM desires to perform banking transactions, the user can connect the personal ATM to a network that offers the desired services. For example, if a user wishes to dispense cash, the personal ATM can be placed in operative connection with a Jini enabled host ATM that includes a cash dispenser service. The personal ATM can discover and join with the host ATM and use a proxy to the cash dispenser service to dispense cash. The personal ATM may be operative to prompt the user to select an account from which to receive the money and the amount desired. The information associated with the selected account and the amount desired are sent to the cash dispenser service with method calls of the cash dispenser proxy. After validating the account information, the cash dispenser will dispense the cash and have the selected account debited.
Such a personal ATM can dynamically connect with banking services of a host ATM to deposit cash or checks and to transfer value between accounts. In addition, the personal ATM can connect to other types of devices that accept value as payment. For example, the personal ATM could connect with a Point of Sale (POS) service to transfer account information for payment of a bill. The personal ATM may connect with a Jini enabled dispenser service to pay for the dispense of items such as medication, snack foods, or any other item that dispensers and vending machines have to offer. The personal ATM of the present invention is operative to dynamically connect with any additional Jini service for transferring value from or to the service.

BEST MODES FOR CARRYING OUT INVENTION Referring now to the drawings and particularly toFIG. 1, there is shown therein, a schematic view of anATM10 that includes a number of transaction services, including anapplication12 which is referred to herein as a user interface service. The exemplary ATM further includes acash dispenser service14, aprint service16, and acard reader service18. Each of these services is connected to acommon network20. The ATM also includes alookup service22 that is responsible for registering new services on the network and providing a repository of service proxies of the services connected to the network.
The ATM also includes ahost service23 that is operative to pass transaction messages between the ATM and anexternal network25.Network25 is connected to at least onehost system24 and preferably a plurality of host systems used in connection with banking systems or clearinghouses.Host system24 is typically responsible for transaction processing related to such tasks as validating a user's card and PIN numbers, debiting a withdrawal of money from a checking account and other transactions.
Each service is operative to communicate with each of the other services through thenetwork20. One advantage of using a network to connect services in an ATM is that services are no longer limited to being connected to a proprietary ATM communication bus.FIG. 2 shows an exemplary embodiment of an ATM system with multiple groups of services inATMs40,42, and44 connected to acommon network56. Each of these ATM services groups has the ability to communicate with aserver computer46 that is responsible for sendingtransaction messages49 to anexternal host system48 on behalf of each ATM services group. In this embodiment alookup service47 operates to register each ATM services group and includes a program that resides on the server computer. However, in alternative embodiments the lookup service may be an independent service attached to the network. In other embodiments each group of services in an ATM could have its own lookup service.
ATM40 is an exemplary embodiment of the invention in which services50,52,54, and55 are independently connected to thenetwork56. In the exemplary embodiment the network may be an Ethernet network using TCP/IP protocol. Each service has its own JP address. The IP address for example could be automatically assigned or obtained from DHCP server. Each of the services in the group which is included inATM40 registers with thelookup service47 and communicates through thenetwork56.
ATM42 is an exemplary embodiment in which only anetwork computer58 is physically connected to thenetwork56. Examples of a computer that may be used in this embodiment, include an Intel® based PC, a proprietary computer, a dedicated Java® workstation, or any other type of machine that is capable of connecting to a network, and running a JVM. Theuser interface service64 and alocal lookup service63, are preferably Java® programs that run on the JVM of thenetwork computer58. However, such services and related service proxies can be generated from other languages and programing tools as long as the generated byte code executes in a JVM. Of course in other embodiments other types of virtual machines may be used.
Transaction services such as acard reader service60,print service61, and acash dispenser service62 are connected to anetwork66 that is local to thenetwork computer58. Thislocal network66 could be based network topologies such as Universal Serial Bus (USB), Firewire IEEE 1394 or any type of connection that allows devices to communicate with each other. Alocal lookup service63 is responsible for registering local services attached to thelocal network66.
ATM44 is an exemplary embodiment where only auser interface service70 is in operative connection with thenetwork56. Transaction services such as acash dispenser72, alookup service77, and aprinter service75 are connected to alocal network80. Here however, some of the transaction devices such as acard reader76 and abiometric scanner78 are older legacy devices that do not have the characteristics of a transaction service.
To accommodate these legacy devices inATM44, this embodiment includes a special bus service74 which acts as a router between other services on thelocal network80 and thelegacy devices76 and78. The bus service74 is operative in a manner similar to other services on the network, however, instead of having a single hardware function, it controls multiple hardware devices. From the point of view of other services, such as the user interface service, each of the legacy devices appears to be an independent service object. The bus service is responsible for translating and routing the service communication into the specific hardware signals needed to operate the legacy devices.
FIG. 3 is a schematic exemplar y view of anATM90 withnetworked transaction services108,110, and112. The system includes anetwork computer100. The network computer is operative to execute a user interface service. The user interface service is operative to cause the display of a user interface output on anoutput service102 such as a computer screen, and which accepts inputs from aninput service104 which includes a keypad, touch screen component or other input device. The network computer also includes anetwork interface109 for connecting to thecommon network106 of the ATM. As discussed above thisnetwork106 does not necessarily have to include an Ethernet type network. The present invention is not limited to any particular type of network for connecting services. Hence the network could be based on such architectures as the Universal Serial Bus (USB) or Firewire IEEE-1394.
In the exemplary embodiment each transaction service also conforms to the JINI™ specification. Each service includes a processor such asCPU118 and amemory120 for running Java® programs in a JVM.Exemplary service112 includes anetwork interface114 for connecting to thenetwork106. The service also includes storage such as a disk,NVRAM122 or other type of data store. Thestorage122 is used to hold Java® objects and proxies which facilitate communication with other services on the network. The processor operates responsive to the stored programs.
The software components that are included with each service are schematically represented for the exemplary embodiment inFIG. 4. Anexemplary service130 used in connection with the present invention includes aJVM140 which is operative to run programs written with Java® Development Kit® (JDK)Classes142. Because transaction services typically perform a narrowly defined hardware function, a large portion of theJDK142 does not need to be included with each service. JDK classes for building a graphical user interface are not needed in services such as a cash dispenser. Thus the JDK can be reduced in size to reduce the storage requirements of the service.
Theservice130 also includes anetwork configuration object144 which in the exemplary embodiment conforms to the JINI™ registration specifications for “discovering” and “joining” with the network. As part of this discovery process theservice130 downloads alookup service proxy164 from alookup service162 which is located on the network with other transaction services that comprise the ATM. A copy of thislookup service proxy146 is stored with theservice130 and is used by the service to join the ATM network.
During registration with thelookup service162, theservice130 will upload acopy166 of aservice proxy148 stored in association withservice130, to thelookup service162. In the exemplary embodiment thisservice proxy148 is a Java® object that enables other services or programs such as auser interface service168 to remotely invoke methods of theservice130 across a network.
Theservice130 may also include other software components such as ahardware control object150 that includes methods for controlling the underlying hardware device functions152 of theservice130. In the exemplary embodiment a service such as theuser interface service168 causes its associated processor to operate to acquire thecopy170 of theservice proxy166 from the lookup service which serves as a repository for such proxies, and invokes methods of the copy of theservice proxy170 to have thehardware control object150 operate the device hardware functions152 of the service.
Although the exemplary embodiment uses Java® objects running inside a JVM on each service, an alternate form of the service can be created that does not have a JVM. Such a service however, may have the instructions for interacting with a network that are hard coded into the firmware of the service. This approach may be appropriate for an inexpensive service that cannot justify the added expense of a dedicated CPU and memory. Unfortunately, the hard coding of methods for registration and security into firmware may limit the ability of the lookup service to evolve. Hence, such services may be designed to include a process for updating the firmware. Also future versions of the lookup service may maintain the same methods for registration and security so as to be able to continue to communicate with these hard coded services.
JVM enabled services do not have this limitation, because they can download an updated lookup service proxy during the discovery stage. Also JVM enabled services also have the ability to download and invoke the methods of service proxies for new or different type services.
FIGS. 5-8 schematically show exemplary protocols for registering transaction services on an ATM network, and communicating with services.FIG. 5 shows an exemplary embodiment of a “discovery”protocol190. Here aservice200 has been newly connected to a network. The service has network configuration objects202 that are operative to send adiscovery request message206 out on the network. Thisrequest206 is preferably multicasted to all lookup services that might be present (in TCP/IP environments the network protocol used may be multicast UDP). In alternate environments, services may be operative to unicast a request to a specific lookup service using its known IP or URL address.
Therequest206 includes asource address207 such as the IP address of theservice200. Eachlookup service208 on the network is operative to respond to the request message with adiscovery response210. Because thesource address207 of theservice200 is known, thediscovery response210 is not multicasted to all services, but is unicast directly to the service initiating the discovery.
Theresponse210 includes acopy212 of thelookup service proxy209 for remotely invoking methods of thelookup service208. In the exemplary embodiment the lookup service proxy is a Java® class with methods for: registering with the network; negotiating leases for the amount of time the service can be connected to the ATM network; and for looking up other services on the network based on a search criteria.
FIG. 6 schematically represents a “join”protocol220. Here the network configuration objects202 of theservice200 invoke a registration method of thelookup proxy212. This method is operative to sendregistration data224 that includes acopy226 of aservice proxy222 andspecific attributes228 of the service to thelookup service208. These attributes define the characteristic of the particular type of service. For example if the service is a printer, the attributes may specify that the printer is a color printer. Thelookup service208 preferably stores all uploaded service proxies in aproxy storage area229.
Once a service has joined the network, its service proxy is available for other services on the network to download.FIG. 7 schematically represents alookup protocol230 of the exemplary embodiment. Here auser interface service231 invokes a lookup method of thelookup service proxy233 that performs a search of alookup service232 for a specific service. The lookupsearch method arguments242 include atype244 of service that is desired and a list ofspecific attributes246. For example, if the user interface service requires a connection to a color printer, thearguments242 of the lookup search specify a service of type “printer” and attributes of “color”.
Thelookup service232 is operative to identify which of the registeredservices236,238, and240 in theproxy storage234 match thesearch arguments242. The lookup service sends theresults248 of the lookup to thesearching service231. The results include acopy250 of any matching service proxies (in this case a copy of printer service proxy236) andcorresponding attributes252.
Once a service has acquired a service proxy to a service, it may invoke methods and register for event notification from that service.FIG. 8 schematically represents an exemplary method for service to service communication. Here auser interface service262 has obtained theservice proxies264 and266 for two services: aprinter service268 and acard reader service277.
Theuser interface service262 is operative to invoke method calls274 and282 from the service proxies which remotely invoke methods of hardware controller objects270 and278, respectively. The hardware controller object methods in turn control thefunctional hardware elements272 and280 of the respective services. For example, aprint service proxy264 for aprinter service268 has a print method with text data as an argument. Calling the print method will remotely call the corresponding print method on theprinter service268 which physically has thehardware272 print out the text.
The methods of the proxies do not necessarily correspond one to one with the methods of the hardware controller objects. The methods of the proxies can perform various types of validations or manipulations of the method arguments before remotely calling methods in the service. For example, the print methods for a printer service may accept images in bitmap format only. However, the corresponding print method of the proxy for the printer service may include addition processing functionality to convert images from other formats to a bitmap format before calling the remote functions of the print service. In addition the proxy methods may invoke combinations of remote methods in the service to perform the desired operation.
In other embodiments such as where the printer service is in the form of firmware, the printer service proxy may be operative to send messages over the network with a proprietary protocol that can directly control the printer hardware.
In the exemplary embodiment of the present invention, services are also operative to have the service proxies register for event notification from the service. For example, the print service may include a complete event. When theprinter service268 has completed printing text it calls this event. If the user interface has registered this event, theprinter service268 will send anevent notification276 to the user interface service remotely across the network whenever a printer operation is completed.
As discussed above the user interface or application in the exemplary embodiment is also a service. Hence transaction services such as acard reader service277 are operative to remotely invoke method calls288 and register forevent notification290 with the user interface service.
Acard reader service277 of the exemplary embodiment is operative to acquire auser interface proxy286 from a lookup service. This proxy will allow the card reader to invoke methods of the user interface such as an activation method, when the card reader first detects that a card is inserted into the reader.
In the exemplary embodiment the method for calling methods remotely from one service to another, and invoking events remotely is a function of the Java® Remote Method Invocation (RMI) classes in the JDK. The RMI protocol facilitates the ability of a service to invoke methods of another service across a network. RMI allows both data and full Java® objects to be passed from one service to another.
One of the advantages of using RMI for communicating with services across the network of an ATM, is that the physical hardware of a service appears from the programmer's point of view as just another Java® object with methods for performing certain functions. Such a system is much easier to develop and modify, because the programmer of an ATM user interface no longer is required to understand all the intricacies of the low level hardware of a service.
In the exemplary embodiment, the configuration of the apparatus and system is automatically changed in response to the connection and removal of services. As previously discussed, each service that is connected to the ATM, registers with a lookup service (and/or other services) through operation of the processors associated with each service. This registration is effective for a period of time which is referred to as a “lease”. When the lease expires the service (if it is still connected) reregisters and thereby negotiates a new lease with the lookup service and/or other services. If the service is disconnected the current lease expires and is not renewed. When this occurs the service is automatically eliminated from the ATM configuration. Preferably the lease periods are set so that removed services cease to be registered before methods thereof are attempted to be invoked. For example in some ATM embodiments it may be desirable to require each service that is present to negotiate a new lease at the start of each transaction so that the configuration of available services for carrying out the transaction is determined. Of course other lease periods, and lease periods which differ depending on the character of the particular service may also be used.
The embodiments discussed above have a lookup service that is responsible for registering services on the network and which serves as a repository for service proxies. In alternate embodiments of the present invention the ATM may be operative to function without a lookup service.FIG. 9 is a schematic representation of adiscovery announcement protocol350. In the discovery announcement protocol auser interface service352 is operative to initiate the discovery process between itself and other services on the network, whereby the user interface acquires aservice proxy354 directly from individual transaction services358.
When theuser interface service352 is first connected to the network and periodically thereafter, it is operative to multicast adiscovery announcement362 across thenetwork364 which requests that services on the network begin the discovery process and register with it. Interested services upon receiving this announcement are operative to unicast adiscovery request366 directly to the announcinguser interface service352 rather than to a lookup service. The user interface service then participates in the “discovery” and “join” processes just as if it were a lookup service.
In addition thisdiscovery announcement protocol350 can also be used by a lookup service, in cases when a lookup service is added to a network with preexisting services. In this case the lookup service can announce its presence on the network with the discovery announcement so that services will register with it.
The exemplary embodiment of the present invention includes services that are fully capable of configuring themselves on the network. However, for legacy services or new services that do not have a network interface, a special bus service can be employed as discussed above.FIG. 10 is a schematic representation of anATM bus service300 that enables the connection ofdevices302 and304 (in this case a printer and a cash or sheet dispenser, respectively) that do not include object oriented and networkable features.
Herebus service300 includes all the elements of other transaction services. It includes aCPU306, amemory307,storage312, and aJVM314 for running Java® programs for discovering and joining a network. For legacy devices the service bus may come pre-loaded with multiple service proxies for each hardware service that can be physically attached to the service bus. Physical attachment may be with anRS232 serial connection for example, or via a proprietary connection. The service proxies are uploaded to the lookup service during the join process of the bus service. From the point of view of other services on the network, all of the legacy services appear to be objects capable of receiving remote method calls. The bus itself handles the routing of messages between the network and the legacy services.
In this described embodiment of thebus service300, thedevices302 and304 include storage for downloadable software objects. As shown schematically with reference toprinter device302, thisstorage309 is used to holdservice proxy308 and ahardware controller object310. Thebus service300 is operative to download a copy of theservice proxy312 and a copy of the hardware control object311 from thedevice302. When the bus service connects to alookup service315, the bus service is operative to upload a copy of theservice proxy312 to thelookup service315 using the discovery and join protocols as discussed previously. Other services on the network may then acquire a copy of the service proxy from thelookup service315.
The bushardware controller object311 runs in theJVM314 of thebus service300 and has methods for controlling the physical hardware of thedevice302. When theuser interface service316 invokes a service proxy method call318 across thenetwork317, the bushardware controller object315 executing in theJVM314 is operative to control thedevice302. From the point of view of theuser interface service316 or another service on the network, thedevices302 and304 appear to be object oriented services.
The devices for thisbus service300 are a hybrid between the complete slave legacy devices of the prior art and the full network enabled services. These hybrid services include their own service proxies, but do not require a CPU and memory for running a JVM. Although they have a lower cost to produce, they are intimately tied to the bus design. Also, the bus hardware must have a specific connection for each type of device.
One of the advantages of an ATM with networkable transaction services, is that the form of the ATM is flexible. Prior art ATMs are limited in the number of serial and parallel ports that are available for connecting peripherals. When all the ports are filled, a new communication card with additional ports must be installed in the ATM. An ATM that uses networkable transaction services can scale to include as many services as the bandwidth of the particular network topology can handle. With an Ethernet network based on 10-base-T for example, theoretically hundreds of Jini enabled devices could be connected to the network of an ATM. Of course a prior art ATM would rarely require more than a dozen or so peripheral devices. However, the ability to easily connect a large number of transaction services creates new opportunities for designing ATMs.
FIG. 11 shows an alternative embodiment of anATM380 in which a singleATM server computer382 is in operative connection with anetwork384 that connects a plurality ofdifferent ATM workstations386,388, and390. Each ATM workstation comprises a set of transaction services. However because, each service is in network communication with acommon server computer382, all threeATM workstations386,388, and390 can be controlled by a single Jini enabledapplication392. Thisapplication392 uses service proxies for each transaction service to control the functionality of each of the three ATM workstations.
In this example theATM workstation386 includes anoutput service394 which includes a graphical display, aninput device service396 such as a keypad, acash dispenser service398, aprint service400, and acard reader service402. Each of these services is Jini enabled and are operative to discover and join with alookup service404 when the services are first installed on thenetwork384. Theapplication service392 controls each service, and is operative to have an independent ATM interface be displayed with each ofoutput service394 andoutput services406 and408 onATM workstations388 and390 respectively. Thus asingle ATM server382 can manage a plurality of independently operable ATM workstations.
Such a design offers advantages over prior art designs. To upgrade the interface menus for each ATM workstation, only theapplication service392 located on theATM server382 needs to be upgraded. This design offers centralized configuration, management, and security, and allows the physical components of each ATM workstation to be easily upgraded by replacing or plugging in additional Jini enabled transaction services.
The exemplary embodiments of the ATMs previously discussed have primarily been concerned with using Jini protocols to produce an improved ATM comprising networkable transaction services. However, the ability to configure an ATM without requiring an operator to load new device drivers from a CD-ROM for example, offers the unexpected benefits of producing an ATM that can be configured on the fly depending on the needs of its owner. Hence an alternative embodiment of the ATM of the present invention is one that is portable and that connects to transaction devices as needed. Such an ATM could be personally owned by a private individual and be used to conduct personal banking transactions, to pay for purchases, and to store electronic money. Further, personal account information relating to credit cards, utility customer numbers, medical plan numbers, debit cards, and information corresponding to any other type of account that money or value is either transferred to or from, can be stored in the personal ATM. In addition, the inclusion of multiple types of account information and means for storing value in a single personal ATM, reduces the need for a person to carry numerous types of credit and banking cards.
For this embodiment a portable device that is operative to run a JVM and to connect to a network using discovery/join/lookup protocols such as Jini, can be used. Examples include a notebook computer, a cell phone, a pager, and a Personal Digital Assistant (PDA). As a personal ATM, such devices are configured to run a personal ATM service application that performs banking operations as is done at non-portable ATM workstations. Unlike prior art ATMs, these portable devices do not include attached currency dispensers. However, because the personal ATM service is Jini enabled, it can connect to additional transaction services as needed, such as a cash dispenser service of a Jini enabled public or multi-user ATM workstation. Such a public or multi-user ATM that is operative to allow personal ATMs to connect to it is referred to herein as a host ATM.
FIG. 12 shows a schematic representation of an exemplarypersonal ATM500. Thepersonal ATM500 is shown in connection with various types of transaction services. Some of these transactions services are local connections to the physical personal ATM including aprint service502 such as an attached printer, amodem service510 such as an attached PC card modem, and acard reader service512 such as a smart card reader. The printer service can be used to print banking transaction receipts or even full account statements. The modem service can provide a connection to a dedicated host banking system such as an online banking system clearinghouse through which a user can accomplish transactions such as transfers of money between accounts, payment of bills or purchases of goods or services. Thecard reader service512 can provide access to a smart card for storing electronic money, or to read the account information from a magnetic-stripe card or other article.
Thepersonal ATM500 can be temporarily connected to another Jini enabled ATM that includes additional services. Anexemplary host ATM504 can provide access to services for withdrawing cash from acash dispenser service516, for depositing cash with acash recycler service518, and for depositing envelopes with anenvelope deposit service520. Further if desired and/or if the personal ATM does not have its own modem service, thehost ATM504 can provide access to a hostbanking system service522. The host ATM can also provide access to other types of services not included with the personal ATM. For example, if thepersonal ATM500 does not have its own card reader, thehost ATM504 can provide access to acard reader service514.
Thepersonal ATM500 can temporarily connect to other types of host machines which provide services. Examples include a point of sale (POS)service506 which may be a part of a payment terminal located in the checkout line of a grocery store, a medical item dispensingmachine service524 located at a pharmacy, a medical payment terminal located in a doctor's office, or even someone else'spersonal ATM service526. Such connections allow the personal ATM to directly pay for purchases by transmitting information which identifies the user's personal credit card or debit card accounts stored locally in adata store528 in thepersonal ATM500. The personal ATM may also be operative to store electronic money in local memory in an encrypted format, and may transfer the electronic money to a connected service such as themedical dispenser service524 to pay for a dispensed medical item. For personal ATMs that have access to the Internet, anInternet service508 can provide access to a hostbanking system service530 or abill paying service532.
The examples of computing devices such as cell phones and PDAs that may be suitable for use as a personal ATM typically include local displays and input devices. However, the present invention also encompasses other computing devices such as smart cards which do not have displays and input devices. Any smart card that includes a CPU, memory, and a non-volatile storage for running a JVM, or includes dedicated firmware for interacting with other services using Jini protocols, or other comparable components and features, may also be used as the computing system of the personal ATM of the present invention.
To interact with a personal ATM on a smart card, the smart card can be put in operative connection with anoutput service536 such as a display screen and aninput service534 such as a keypad. In the preferred exemplary embodiment this is accomplished by inserting the smart card into a smart card reader of a Jini enabled host ATM or some other host machine that includes a display and input device. An example of such a machine is a notebook computer. Once connected, the smart card can use the discover/join/lookup protocols to pass service proxies between itself and the host machine.
In one exemplary embodiment the smart card downloads proxies for the display and input services of the host computer. These proxies are used by the personal ATM service(s) in the smart card to display an ATM menu screen on the output service of the host machine, and to receive input signals from the input device of the host machine.
In an alternative embodiment, rather than downloading display and input services, the personal ATM service(s) on the smart card uploads a personal ATM proxy service(s) to the host machine. This proxy includes a Java interface application which runs in the JVM of the computer system of the host machine. The Java application creates a user interactive ATM menu interface which displays on the output device of the host machine and accepts inputs from the input device of the host machine.
This described embodiment divides the functionality of the personal ATM across different computer systems. The personal ATM service(s) on the smart card may perform back-end operations of maintaining a data store of accounts, validating passwords, and/or storing electronic money, whereas the host computer executes the front-end interactive GUI application for interfacing with the personal ATM service(s) on the smart card as well as other services.
FIG. 13 schematically represents a Jini enabledhost ATM540. This host ATM is operative as a stand alone ATM terminal and includes services such as acash dispenser541. However,host ATM540 also includes one or moreexternal network ports550 that allow personal ATMs to connect with the host ATM. Theseports550 provide an access point for Jini enabledcell phones542,notebooks544,pagers546,PDAs548 and other devices that are operative as Jini enabled personal ATMs, which enables such devices to use the publicly available services of the host ATM. Once a personal ATM has discovered and joined with the Jini network of the host ATM, the personal ATM is operative to lookup and interact with available services, such as thecash dispenser541.
For a personal ATM on a smart card, the host ATM includes asmart card interface554 such as a smart card reader or a contactless interface for communicating with the card. Once the smart card is in operative connection with the host ATM, the service(s) on the smart card is operative to discover and join with the Jini network associated with the host ATM, just as the other described personal ATM computing devices.
The personal ATM on a smart card uses the display556 andkeypad558 of thehost ATM540 to generate an interactive ATM interface menu for enabling interaction with a personal ATM service or several services on the smart card. For computing devices with built in displays, such as thePDA548, the personal ATM user interface can be produced on theirown display screen549. Alternatively, such devices can use the display and keypad of thehost ATM540, as is done by the smart cardpersonal ATM552.
Once a personal ATM is connected to thehost ATM540, it may be operative to interact to perform such tasks as withdraw cash, receive deposits, and to transfer money to and from any of the accounts for which data is stored in the personal ATM and/or for which data representative of electronic money is stored in connection with the personal ATM.
FIG. 14 schematically represents embodiments ofpersonal ATMs560 and562 that are operative to discover and join with a Jini enabled host Point of Sale (POS) service which resides on aPOS terminal564. Once connected to the POS service, the personal ATM is operative for example to pay for purchases by transferring account information stored in the data store of the personal ATM to the POS service.
FIG. 15 schematically represents embodiments ofpersonal ATM566 that is resident on a smart card.Personal ATM566 may be placed in operative connection with a Jini enabled computing device such ashost notebook computer568 through an appropriate interface. Once thepersonal ATM566 has discovered and joined with thenotebook computer568, the notebook computer is operative to lookup the personal ATM proxy for the personal ATM. This ATM proxy is operative to display a Java based ATM user interactive menu on thenotebook display569. In addition, services of the notebook, such as anInternet connection service570 are available for use by thepersonal ATM566. The ATM proxy is operative to enable menu options for performing banking or other transactions such as transferring money between accounts and paying for purchases by using theInternet service570 of thenotebook568.
FIG. 16 schematically represents an embodiment of thepersonal ATM572 that is operative to discover and join with the Jini network of a secondpersonal ATM574. In this manner the firstpersonal ATM572 is enabled to transfer data representative of electronic money to the secondpersonal ATM574. Also, each personal ATMs could share services with the other for purposes of carrying out transactions.
FIG. 17 schematically represents a Jini enabledhost dispenser578 that dispenses medical items. Host dispenser is operative to havepersonal ATMs576 and580 discover and join with it. Thedispenser578 includes a dispenser proxy which includes an interactive Java application for selecting items to purchase and dispense. For personal ATMs that include their own local display services, the dispenser proxy interface application can be uploaded and executed in the local JVM of the personal ATM. In other embodiments, as with embodiments of the personal ATM on a smart card, the dispenser interface application executes in the computing system of the dispenser and is operative to interact with the personal ATM through the personal ATM proxy.
Once a user has selected items to purchase with the dispenser proxy interface application, the personal ATM service is triggered by the dispenser service to make payment. This may be accomplished by either transferring electronic money or by providing credit/debit account information stored in the personal ATM. This information is used to accomplish payment and an appropriate record is made in the dispenser and the personal ATM.
FIG. 18 schematically represents apersonal ATM582 in operative connection with ahost ATM584. Here the personal ATM includes acomputing device581 with a processor such as a PDA or cell phone with alocal display screen596. The personal ATM is operative to run aJVM586 with aJDK588 andJini Classes590. The personal ATM also includes adata store592 that includes account information for credit cards, debit cards, and any other account which is a source of value. Thepersonal ATM582 further includes apersonal ATM service594 that is operative to output an interactiveATM interface menu598 on thedisplay screen596.
Thepersonal ATM582 is operative to discover and join with thehost ATM584 which includes anATM lookup service600 and other transaction services such as acash dispenser service602,cash recycler service604, andbanking network service606. The personal ATM is further operative to cause the processor to operate to look up these public services and to download corresponding proxies such asproxy608. The personal ATM uses these proxies to interact with the host ATM responsive to human interaction with theATM interface menu598 of thepersonal ATM582.
In this described exemplary embodiment thepersonal ATM service594 is operative to generate auser interface menu598 responsive to the types of public services that are available athost ATM584. However, in alternative embodiments, the personal ATM may display a user interface menu that originates from the host machine. For example, when thepersonal ATM582 joins with thehost ATM584, the personal ATM may lookup and retrieve a high level host ATM service proxy that encapsulates the functions of all of the publicly available services of the ATM host. Such a high level service proxy may include the necessary programming to display auser interface menu598 with thedisplay screen596 of thepersonal ATM582 for having thehost ATM584 perform a plurality of different types of transactions.
In another alternative embodiment the personal ATM may include abrowser software function599. The high level host service proxy may direct thebrowser599 to retrieve from thehost ATM584 one or moreuser interface pages601 for display in thebrowser599. Suchuser interface pages601 may include Hyper Text Markup Language (HTML), Extensible Markup Language (XML), Wireless Markup Language (WML), Java script, and any other type of instruction language that is operative to have thebrowser599 output aninteractive interface598 withdisplay screen596 of thepersonal ATM582.
It is recognized that different types of personal ATMs may have different types ofdisplay screens596 with different performance characteristics. For example, a notebook computer may have a relatively large high resolution graphic display, whereas a cell phone may have a small low resolution character-based display. To accommodate either type of display, the exemplary embodiment of the present invention is operative to format theinterface menu598 responsive to the specifications of thedisplay screen596. For example if theinterface menu598 is generated by a high level service proxy, the service proxy is operative to output indicia for theinterface menu598 in a format that is appropriate for thedisplay screen596. If the interface menu is displayed in a browser responsive to interface pages, the personal ATM is operative to retrieve interface pages from thehost ATM584 that correspond to the display characteristic of thedisplay screen596.
This may be achieved by a host ATM that includes a plurality of different service proxies that correspond to different types of display screens. For example the host ATM may include service proxies for character based cell phone display screens and service proxies for graphical VGA display screens. The personal ATM may lookup and retrieve the service proxy that matches its particular resolution. In an alternative embodiment, the service proxy may be operative to determine the resolution of thedisplay screen596 when it is executed in theJVM586 of thepersonal ATM582. Based on this determination the service proxy may then construct and output a properly formattedinterface menu598 responsive to the determined resolution of the display screen.
For embodiments of the host ATM that include abrowser599 for displaying interface pages, the host ATM may include different sets of these interface pages which are formatted for different resolutions and/or types of personal ATM display screens. Once the personal ATM has joined with the host ATM, the personal ATM is operative to retrieve the proper set of instruction pages responsive to the type of display screen that is being used.
FIG. 19 schematically represents an alternative embodiment in which thepersonal ATM610 resides on a smartcard computing device612. Here thepersonal ATM610 is in operative connection with ahost ATM614. However, rather than downloading proxies to thevarious transaction services616,618, and620 from thehost ATM614, thepersonal ATM610 uploads at least onepersonal ATM proxy622 that is operative in theJVM624 of thehost ATM614. The personal ATM proxy includes a Java ATM interface application that is operative to output an interactiveATM interface menu626 on thedisplay screen628 of thehost ATM614.
Thepersonal ATM proxy622 is also operative to remotely call personal ATM object methods of thepersonal ATM service630 operative in theJVM632 of thepersonal ATM610.
In this exemplary embodiment, the personal ATM comprises any computing device that includes a CPU, memory, and non-volatile storage operative to run a JVM, wherein Java objects running in the JVM are operative to discover and join with a network. However, other embodiments of the personal ATM may employ firmware that is specifically designed to interface with services on a network using discover and join protocols such as Jini. Other embodiments of the personal ATM may employ other networking protocols and systems that are operative to have devices automatically configure themselves on a network by passing internally stored device drivers across the network.
FIG. 20 schematically represents the process by which a personal ATM such as the personal ATM shown inFIG. 18 initially operates. In this embodiment, the computing device includes its own local display screen. The personal ATM computing device is first activated by either manually activating the device on instep700, or activating the device by some other method such as sensing a network connection. Once activated, the personal ATM is operative to execute the personal ATM service instep702. The personal ATM service is an application which is either manually started by the user of the apparatus, or is automatically started by the operating system of the personal ATM computer.
Next the personal ATM service displays a login screen instep704 which requires the user to enter a password which serves as validating data. In embodiments of the invention the validating data may include a code, thumb or finger prints, iris or retina scans or other biometric or other data that is capable of identifying a user, or combinations of such inputs. After a user enters a password instep706, the personal ATM service validates the password in step708. If the validation fails the personal ATM service jumps to step706 and redisplays the login screen. If the validation succeeds the personal ATM service discovers and joins with a lookup service on the network instep710. After joining the network, the personal ATM performs a lookup of available services on the network instep712. The personal ATM instep714 displays a list of selectable menu items in a personal ATM main menu screen. This list corresponds to the types of services that are available. For example if the network includes a cash dispenser, the personal ATM service will display a menu item for withdrawing cash. Instep716 the personal ATM service waits for a user to select one of the menu items.
FIG. 21 schematically represents the method steps that are employed with a personal ATM as described with reference toFIG. 19. Here a personal ATM comprising a smart card is activated instep720 by inserting the card into a smart card interface of a host machine. In an exemplary embodiment both the card and the host machine would use Jini protocols to configure and communicate with each other; however, alternate embodiments can use other network protocols operative to allow the smart card to automatically upload a personal ATM interface application to the host ATM. As discussed above, examples of host machines can include Jini enabled ATMs, dispensers, notebook computers, point of sale devices, and other personal ATMs.
Once activated, the smart card instep722 performs Jini discovery and join with the lookup service of the host machine. As part of the join process the personal ATM uploads at least one personal ATM proxy to the host machine. Instep724 the host machine runs the personal ATM proxy in the JVM of the host machine which is operative instep726 to display a login screen on the output device of the host machine. After the user enters a password or other validating data instep728 through at least one input device of host machine, the personal ATM proxy instep730 remotely calls a validate method of the personal ATM service running in the JVM of the smart card. This validate method is operative to test for validity of the identifying data entered in the host machine input service by comparing the identifying data with data stored in a data store of the smart card. The personal ATM service is further operative to pass the results of the validation test back to the calling personal ATM proxy. If the validation test failed the personal ATM proxy redisplays the login screen at726 and waits for a user to reenter validating data. If the validation test succeeded as a result of correspondence between input data and stored data, the personal ATM proxy instep734 performs a lookup of available Jini services. Instep736 the personal ATM proxy displays a personal ATM main menu on the output device of the host machine responsive to the types of available services. Instep738 the personal ATM proxy waits for a user to select one of the menu options with the input service of the host machine.
In the described embodiment, the personal ATM proxy includes its own Java application for displaying an ATM menu. However, in other embodiments, the host machine can include its own interface application. This host interface application would request that the user input validation information. To validate a password for example, the host application calls the validation method of the personal ATM service in the smart card using the object functions of the personal ATM proxy. To perform other transactions which require data stored on the smart card the host application may call other methods of the personal ATM proxy to retrieve this data.
FIGS. 22-25 are exemplary methods for using the personal ATM to withdraw cash, to pay a bill, and to dispense a medical item. All of these methods continue from the point where the personal ATM is displaying the personal ATM main menu. These methods are applicable for either of the processes described inFIGS. 20 and 21. For embodiments that use a computing device such as a PDA, the personal ATM menu is displayed on the local output device of the PDA. For smart card embodiments, the personal ATM menu is displayed on an output device of the host machine.
FIG. 22 shows the process for withdrawing cash from a host ATM. In astep750 the ATM menu option for withdrawing cash is selected by the user. For this menu option the personal ATM displays a “withdrawal from” menu instep752 which lists the available accounts for which information is stored in the data store of the personal ATM. Such accounts can include checking, savings, credit, debit, money market or any other account from which a host ATM is operative to deduct value. The personal ATM can include local data storage representative of accounts for electronic money, food stamp credits, college cafeteria points or any other type of stored value which is transferred from the personal ATM to the host ATM.
After the user selects an account instep754, the personal ATM requires the user to enter a withdrawal amount instep756. Next the personal ATM instep758 sends the account information associated with the selected account and the withdrawal amount to the host ATM by calling withdraw methods of a cash dispenser proxy.
The host ATM is operative to validate the account information. If the withdrawal validation fails the host ATM triggers a validation event or method in the personal ATM with a false value instep762. Consequently the personal ATM instep764 displays an error message and returns to step752 to display the “withdrawal from” menu.
If the withdrawal validation succeeds instep766 the host ATM dispenses cash with the cash dispenser and has the withdrawal debited from or charged to the selected account. Instep768 the host ATM triggers the validation event or method in the personal ATM with a true value, wherein the personal ATM is operative to jump back to thesteps714 or736 inFIGS. 20 and 21 respectively to display a refreshed personal ATM main menu.
FIG. 23 is representative of a method for paying Value with the personal ATM in connection with a host POS service. In step780 a user selects a “pay bills” menu item from the main menu of the personal ATM. The personal ATM instep782 displays a “payment to” menu with a list of POS terminals that the personal ATM is currently in connection with. After the user selects a POS terminal instep784, the personal ATM displays a “payment from” menu with a list of accounts instep786. After the user selects an account instep788, the personal ATM retrieves the payment amount in step790 from the host POS by calling POS service object methods of the POS proxy.
The personal ATM displays this amount instep800 and requires the user to confirm that this amount is correct. If the amount is confirmed the personal ATM sends the selected account information instep802 to the host POS by calling methods of the POS proxy. Instep804 the host POS validates the transaction using the account information. If the payment is not validated the POS triggers a validation event or method in the personal ATM with a false value instep806. Consequently instep808 the personal ATM displays an error message and returns to step786 where the personal ATM displays the “payment from” menu.
If the validation succeeds instep810 the POS triggers the validation event or method in the personal ATM with a true value and the personal ATM returns to the steps for looking up Jini services and redisplaying the personal ATM main menu.
FIG. 24 is representative of the method steps for dispensing medical items from a dispenser with the personal ATM. After a user selects the “dispense” menu in820 from the main ATM menu, the personal ATM displays in step822 a “dispense” menu with a list of host dispensers available on the Jim Network. If the personal ATM is only in connection with one host dispenser service, the personal ATM is operative to jump fromstep820 to step826.
When a user selects a host dispenser service instep824 the personal ATM downloads a proxy to the selected dispenser. In one exemplary embodiment, the dispenser proxy includes a Java application that is operative to generate a dispenser interface for interacting with the host dispenser service. In alternative embodiments, the dispenser proxy may be operative to have the browser of the personal ATM display interface pages retrieved from the dispenser that correspond to a dispenser interface. In embodiments of the personal ATM on a smart card, the dispenser interface is displayed on the output device of the dispenser. When information such as user identifying information, an account number or credit card number is required, the dispenser is operative to communicate with the personal ATM service on the smart card through a personal ATM proxy.
The dispenser interface application in one exemplary embodiment is an interactive user interface which includes functionality to allow a user to select items to dispense. Such a dispenser interface will typically display items available to dispense prescription data, items selected to dispense, the cost of each item, the total costs of all selected items and/or any other information which may be appropriate and useful for making purchases or obtaining medical items from a dispenser. In exemplary embodiments of the invention these items may be a subset of items available in the dispenser which have been prescribed for the particular user of the personal ATM by a physician or other medical provider and which are selected responsive to a prescription service in connection with the dispenser. Alternatively, the principles of the invention may be applied to systems like that shown in U.S. Pat. No. 5,912,818 which is incorporated herein by reference, in which a medical professional dispenses items for selected patents and records are maintained regarding what the user has taken and each patient has received. Charges may also be appropriately assessed to the patients and inventory may be tracked and restocked as required.
In addition the complexity of the dispenser interface may be generated responsive to the type or resolution of the display device of the personal ATM. For example, if the personal ATM is a cell phone the dispenser interface may be limited to alphanumeric characters, whereas if the personal ATM is a notebook computer the dispenser interface may include complex graphics.
Instep828 the user interacts with the dispenser and selects items to dispense. When the user is finished selecting items to dispense, the dispenser interface instep830 triggers a get payment account event or method of the personal ATM. Consequently instep832 the personal ATM displays a “payment from account” menu with a list of available accounts to pay for the dispense of the selected items.
After the user selects an account instep834, the personal ATM retrieves the payment amount from the host dispenser service with a method call of the dispenser proxy. Instep840 the personal ATM has the user validate that the payment is correct. If the payment is not validated, the personal ATM jumps to step826 and redisplays the dispenser interface.
FIG. 25 is a continuation of the method steps for dispensing items from a host dispenser service as shown inFIG. 24. Here if the payment to the dispenser is confirmed by the user, the personal ATM instep842 sends the selected account information to the host dispenser service using methods of the dispenser proxy. Instep844 if the host dispenser service does not validate the transaction, the host dispenser service is operative to trigger a validation event or method of the personal ATM with a false value in astep846. Consequently the personal ATM instep848 displays a corresponding error and jumps to step832 ofFIG. 24 for displaying the “payment from account” menu.
If the transaction is validated by the host dispenser service, the host dispenser service instep850 dispenses the purchased item. Instep852 the dispenser triggers a validation event or method of the personal ATM with a true value. Consequently the personal ATM jumps to the steps for looking up Jini services and redisplaying the main menu.
FIG. 26 shows screens representative of the ATM interface menu of the personal ATM a personal ATMmain menu900 in this exemplary embodiment includes menu items such astransfer902, withdrawal904, deposit906, pay908, dispense910 and other912. These items are visible responsive to the types of services that the personal ATM is in connection therewith. For example if the service is not in connection with a host ATM service that includes a cash dispenser service, thewithdrawal menu item902 will not be visible.
Selecting the “other”menu item912 for this exemplary embodiment displays a second personal ATM “other”menu914, which includes other features and maintenance options of the personal ATM. Such menu items include editing accounts916, lookup ofother Jini services918, configureservices920, lookup/print account statements922,change password924, and update personal ATM926. The editing accountsmenu item916 enables maintaining account information in the data store. The lookup other Jiniservices menu item918 when selected initiates the Jini lookup of services on the network. The configureservices menu item920 when selected causes the display of further menus which enable the configuration of the services. The lookup/printaccount statements item922 when selected enables the reviewing and printing of account statements. The changepassword menu item924 enables the user to change the main personal ATM password. The update personal ATM menu item926 enables the downloading of a new version of the personal ATM service and supporting software from the Internet or a host ATM.
When the personal ATM is in operative connection with a host ATM or has access to an Internet based host banking system service, the personal ATM may be operated to transfer money between accounts.FIG. 27 is representative of exemplary transfer menus of the personal ATM. The “transfer to”menu930 includes a list of accounts for which data is stored in the data store of the personal ATM. One of these accounts can be selected for transferring value to an account. After selecting a “transfer to” account, the personal-ATM is operative to display a “transfer from”menu932. This menu lists accounts for which data is stored in the data store from which value may be transferred. After selecting a “transfer from” account, the personal ATM prompts the user to enter the amount of value to transfer with a “transfer amount”menu934. Once the user has selected the accounts and the amount of value to transfer, the personal ATM is operative to use the host banking system service at the host ATM or an Internet service to send transaction messages for transferring value between the selected accounts. If the transaction succeeds or if there are errors, the personal ATM is operative to display appropriate additional menus prompting the user for additional information and/or instructions related to continuing or aborting the transaction.
FIG. 28 is representative of menu screens of the personal ATM for withdrawing cash. A personal ATM that is in operative connection with a host ATM with a cash dispenser is further operative to display a “withdrawal from account”menu140 that lists a plurality of accounts stored in the data store of the personal ATM for withdrawing money. Once a user selects the account, the personal ATM prompts the user to enter the amount of cash to dispense with the “withdrawal amount”menu942. After the account and amount information has been entered, the personal ATM is operative to use the cash dispenser proxy methods to initiate the dispensing of cash from the selected account. The cash dispenser service is operative to validate the transaction, to debit or charge the amount of money from the selected account and to dispense the cash to the user.
FIG. 29 is representative of personal ATM interface menus for depositing value. When a personal ATM is in operative connection with a host ATM that includes a cash recycler, envelope or other deposit accepting service, the personal ATM is operative to display a “deposit to”menu950. This menu lists a plurality of accounts stored in the data store of the personal ATM to which money may be deposited. After the user selects an account, the personal ATM is operative to display a “deposit from”menu952 that includes a list of available depository services associated with the host ATM. After selecting the type of service to use, the personal ATM displays a “deposit amount”menu954 that prompts the user for the amount of the cash, the value of a check or value of other item(s) that is being deposited with the deposit services of the host ATM. After entering this information, the personal ATM is operative to have the selected deposit service acquire the cash, envelope or other deposit item from the user and to credit the selected account.
FIG. 30 is representative of personal ATM menu screens for paying value. When a personal ATM is in operative connection with host POS service, the personal ATM is operative to display a “payment to”menu960 with a list of all the POS services that the personal ATM has access to. The user is prompted to select a POS service with which to interface. After selecting a POS service or if there is only one POS service available, the personal ATM will only display the “payment from”menu962, which prompts the user to select one of the accounts stored in the data store for paying for a purchase. After selecting the account, the personal ATM is operative to display a “payment validation”menu964 with the amount of value that the POS service indicates is the payment amount. If the user confirms the payment, the personal ATM service is operative to invoke POS proxy methods to have the POS service initiate the payment from the selected account.
FIG. 31 is representative of personal ATM menus for dispensing items. When the personal ATM is in operative connection with a host dispenser, the personal ATM is further operative to display a “dispense”menu970 with a list of available dispensers. Upon a user selecting one of these, the personal ATM service is operative to use the proxy to the host dispenser to display adispenser interface972 for interacting with the dispenser service. If the personal ATM includes its own display service and input service, the dispenser interface is displayed in the display service of the personal ATM. If the personal ATM resides on a smart card, the dispenser interface is displayed on the display device of the host dispenser and interacts with the smart card service through a personal ATM proxy. Once a user has finished selecting items to dispense, the dispenser service is operative to have the personal ATM display a “payment from”menu974 with a list of accounts stored in the data store of the personal ATM for payment to the dispenser. Upon selecting one of the accounts, the personal ATM is operative to display a “validate payment”menu976 which requests the user to verify that the amount of money the dispenser requires is correct. If the user verifies the amount, the personal ATM is operative to invoke the dispense methods of the dispenser proxy to have the host dispenser debit the selected account and to dispense the selected item.
FIG. 32 is representative of the “edit account”menu980 of the personal ATM. This menu includes a list of all the account information stored in the data store of the personal ATM. This account information includes the name of theaccount982, the type ofaccount984, the password orpin number986 of the account, theaccount number988, the expiration date of theaccount990, and the issuer ID or routing number992 of the account.
In addition to storing information that corresponds to standard banking and credit type accounts, embodiments of the personal ATM may also include local storage for data that is representative of value. The local storage may include information that is representative of points for purchasing food from a cafeteria, food stamps, electronic money or any other data that corresponds to value. For example, electronic money may include encrypted units of value that are stored locally and transferred to other individuals without debiting or crediting an external account or line of credit.
The personal ATM of embodiments of the present invention offers the advantage of storing personal account information and stored value in one password protected and convenient location. Further, embodiments of the personal ATM may include their own interface application and uniform menus, so that a plurality of different types of transactions can be performed with the same familiar and easy to use personal interface. Services that do not exist locally are a simple and automatic connection away. Such connections to host services can be made by plugging the personal ATM into a universal network connection, or by a contact-less connection such as with an IR or RF interface.
Although previously described embodiments discuss the configuration and interaction between a plurality of services on a network, the present exemplary invention may also be applied to interactions between services that are performed off-line. For example, an alternative embodiment of the personal ATM could use a previously retrieved service proxy to prepare and simulate a series of transaction steps off-line prior to connecting to a host ATM. Such simulations may be performed with service proxies that are operative to behave as virtual services. A virtual service for a printer service for example, would respond programmatically just as an actual printer service, but without causing a hardware device to print on paper. Such simulated services in a personal ATM may be useful for testing complex transactions without actually transferring value.
As an example, a personal ATM may be able to access a service for performing complex transactions such as stock market purchases. Such a stock trader service may require value from an account of the personal ATM to be transferred to an account associated with the stock trader service. If the transaction is complex, such as a reallocation of many stocks, the user may choose to assemble and test the transaction off-line using the virtual service features of the service proxy associated with the stock trader service. As part of the process for setting up the trade, the stock trader service proxy may prompt the personal ATM service to have the user select one of the accounts associated with the personal ATM to use for transferring value during the trade. When the user wishes to perform the transaction on-line, the stock trader service proxy can re-run or commit the transaction with the service proxy in communication with stock trader service.
In other alterative embodiments of the present invention, services may be operative to perform transaction off-line as well. For example when a personal ATM is in communication with a service such as the previously described stock trader service, the user may invoke a transaction of the stock trader service that is conditioned on certain events occurring in the future. After the personal ATM has disconnected from the network that includes the stock trader service, the conditional transaction will still be executed if the stock trader service determines that the specified conditions are satisfied. Such conditions could include the purchase of a stock if the price falls to a desired level for example. In this manner a service can act as virtual agent which performs transactions for the user when the communication between the personal ATM and the services has been severed.
As discussed previously, the personal ATM may include a personal ATM service that can be accessed through a personal ATM proxy. In the previously described embodiments, methods of the personal ATM proxy are invoked by a host machine such as a host ATM to perform such actions as validating passwords and retrieving account information. However as a service, the personal ATM can be accessed by other applications as well, including applications that are resident on the same machine as the personal ATM. Such other applications may include accounting software, e-commerce applications, a web page for ordering items from an Internet merchant, or any other application that may require account information for performing transactions.
As a service, the personal ATM may include public methods which allow other applications and other services to access information managed by the personal ATM. Such public personal ATM methods may include methods for retrieving an account to transfer value from or method for retrieving an account to transfer to value to. When such methods are called, the personal ATM service is operative to send a list of accounts to the calling application or service. However, to keep personal account information secure, the public methods of the personal ATM may require a personal ATM password or other validating data as an argument. If personal ATM methods are invoked with a validating argument that is null or incorrect, the personal ATM service may be further operative to prompt the user to enter the password before transferring any information to an external application.
Any application that requires the transfer of value from an account may be configured to interface with the personal ATM using the previously described protocols for service to service communication. This enables the personal ATM to be used as a digital wallet for managing the transfer of value and for performing faster, more convenient, and more secure purchases with external services.
Thus the system and method for connecting services to an ATM of the present invention achieves the above stated objectives, eliminates difficulties encountered in the use of prior devices and systems, solves problems and attains the desirable results described herein.
