Abstract

A method and apparatus for providing cross-marketing and promotional offers to a customer using an electronic tag product identification system is disclosed. The disclosed technology also allows for presenting promotional offers in an automatic check-out process. RFID smart tags are associated with products in a place of purchase or a place of selection of such products. Each distinct product is associated with at least one smart tag, the smart tags containing identification information regarding their respective products. RFID smart tag readers are used to retrieve product information including information concerning promotional offers, purchase prices and expected product weights. Such promotional offers are presented to the customer and may be real-time promotional offers, near real-time promotional offers or generic promotional offers.

Description

TECHNICAL FIELD OF THE INVENTION
• The present invention relates to a system and method for providing cross-marketing and promotional offers to a customer using radio frequency based product identification systems.
BACKGROUND
• Supply Chain Management (SCM) is a common problem for any organization involved in the design, manufacture and distribution of goods. SCM is particularly important in retail organizations where the successful management of product inventory and the promotion of customer satisfaction are essential for efficient operation, customer loyalty, and optimal profit margins. Common SCM activities for product manufacturers as well as retailers include inventory control, supplier network development, purchasing and marketing.
• One of the goals of marketing is to continually enhance customer satisfaction. To enhance customer satisfaction, many retail operations support various manufacturer sponsored promotional offers to customers. Additionally, a retailer may offer its own promotional offers. Many such promotional offers are presented to customers via discount coupons that are redeemable at the point of sale. Coupon promotional offers are well known and normally offer a discount for purchasing a product.
• A similar type of coupon based promotional offer relates to cross-marketing coupons. A manufacturer may issue a cross-marketing coupon in which the purchase of a first product triggers a discount coupon offer for purchasing a second product. Such second product may be a different product (different from the first product) produced by the same manufacturer or for a different product produced by a second manufacturer. A cross-marketing offer is typically for products that are commonly used at the same time (e.g., baby wipes and diapers). Cross-marketing coupons may also be used to promote a customer's “trial use” of an entirely new product or a new and improved version of an existing product.
• Prior art cross-marketing coupon systems typically print cross-marketing coupons directly on a product package or enclosed the coupon within the product package. Such prior art systems exhibit several inherent limitations that adversely affect the effectiveness of cross-marketing promotional offers.
• First, cross-marketing coupons are generally special promotional events valid only for a predetermined length of time and may be intended for distribution to a specific retailer or retailers. Consequently, a manufacturer must interrupt a production line to print retailer specific cross-marketing coupons on the product package or product documentation and then segregate that product from the rest of the product inventory. The additional coupon-printing step and segregation (e.g., special handling and distribution) of the promotional product from the rest of the product inventory adds additional cost to the product, is time consuming and requires substantial lead time for the manufacturer to offer such a promotional event.
• Second, printing cross-marketing coupons directly on a product package or enclosing the coupon within the product package increases customer inconvenience. Such prior art cross-marketing coupon systems would typically require a customer to purchase (perhaps even consume) a “cross-marketing coupon triggering product” before such customer can remove and use the coupon. Such a system would typically require a customer to use a cross-marketing coupon at a later date. Therefore, a customer must both clip coupons and keep track of the clipped coupons until a later time when such coupons are used. Such customer inconveniences reduce the effectiveness of cross-marketing coupon offers as many customers will likely choose not use the coupon at all.
• Third, prior art coupon systems result in longer average check-out times which can contribute to longer check-out lines. Many prior art coupon redemption processes implemented at a point-of-sale (e.g., scanning a product bar code at the check-out counter) are unnecessarily time consuming in today's electronic world. Additionally, customers will almost always resent long check-out lines and may base their future patronage decisions at least in part on memories of long check-out lines. Consequently, promotional offers that result in longer check-out lines have the potential to actually discourage customer patronage.
• Fourth, prior art coupon systems (i.e., paper-based coupons) require a retailer to collect the coupons and then send them to a clearinghouse, which is typically an independent company used by a retailer to sort, count, and submit coupons for payment to manufacturers or their agents on behalf of the retailer. Further, the manufacturer must pay the clearinghouse and the retailer for their role in handling and processing the redeemed coupons. Clearly all costs relating to a coupon program must be considered by the coupon offering party when determining the amount of a coupon offer. Restated, the coupon processing overhead costs will be determined and such costs will reduce the amount of “savings” offered to a customer thereby indirectly passing such processing costs to the customer.
• Fifth, the previously described prior art systems have limited ability to influence a shopper at the point of a purchasing decision, or simply, the point of decision. The point of decision is generally defined as the moment a customer makes a purchasing decision. The point of decision would typically occur, for example, while a shopper is walking through a retailer store examining products. Retailers and manufacturers have long known the importance of the influencing shoppers at the point of decision; however, their efforts to influence a shopper at the point of decision have largely been limited to markings on product package, such as witty slogans or eye catching color schemes and gimmicks such as “blue light special” programs. The above described prior art system of printing cross-marketing promotional offerings on a product's packaging or coupons included inside a product's packaging have limited ability to influence a shopper at the point of decision.
• An alternative to traditional coupons printed on, or enclosed in, a product are electronic coupons. One such system is described in U.S. Pat. No. 5,727,153, issued to Ken R. Powell, and such reference is hereby incorporated for all purposes. Powell U.S. Pat. No. 5,727,153 describes a system for creating, dispensing, and redeeming electronic discount coupons in a store. The system includes a “smart card,” product stations adjacent to selected products in the store and a check-out station. To create an electronic coupon, the customer inserts the card into the product station adjacent to the product the customer wishes to purchase, and the product station then writes an electronic coupon onto the card. The customer continues to shop throughout the store, collecting electronic coupons for products of interest. Upon completing his or her shopping, the customer redeems the electronic coupons at the check-out area by inserting the card into the check-out station. If the product code data (e.g., the Universal Product Code, or UPC) on the product matches data stored on the card, the customer receives the discount. Periodically, the electronic coupon data is transferred to a remote clearing house.
• One limitation of the Powell U.S. Pat. No. 5,727,153 electronic coupon system, however, relates to the “smart card” feature. Using the Powell '153 system, a customer must have in his or her possession a smart card and must repeatedly “scan” the smart card in order to collect and qualify for discount offers. The customer may misplace such card while on a shopping trip. In addition, a customer may not take the time to repeatedly scan the card or may simply forget to scan the card. Further, the Powell '153 electronic coupon system does not provide for cross-marketing offers.
• Therefore a need exists for a cross-marketing promotional process that does any one of the following: (1) provides more flexibility in creating promotional offers by substantially reducing or eliminating the lead time required for a manufacturer to offer a promotional event; (2) provides for “after shipping” cross-marketing promotional offer (i.e. a promotional offer that is conceived and offered after the product is shipped); (3) provides for a cross-marketing promotional process that is more cost-efficient; (4) that minimizes or eliminates customer inconveniences such as longer check-out times, coupon clipping and the necessity to return to the store to use cross-marketing coupons; and (5) provides an improved method for influencing a shopper at the point of a purchasing decision.
SUMMARY
• Objects and advantages of the invention will be set forth in the following description, or may be obvious from the description, or may be learned through practice of the invention.
• The present invention relates to novel implementations of Radio Frequency (RF) based product identification technology and electronic product identification codes, such as EPC codes, in a system and method for providing cross-marketing promotional offers to a customer as well as improved point-of-sale procedures.
• Certain embodiments according to aspects of the present invention will provide significant improvements in promotional offering programs by lowering administrative costs, providing for real-time promotional offers that provide a more dynamic influence on a customer at the point of a purchasing decision while minimizing customer inconvenience and point-of-sale check-out time requirements. One such exemplary embodiment according to aspects of the present invention relates generally to novel implementations of Radio Frequency Identification Device (RFID) technology to assist organizations with various aspects of providing promotional offers such as cross-marketing coupons. Such RFID based systems and methods provide retailers and manufacturers with the ability to issue cost efficient promotional offers to customers in real-time if desired.
• Generally speaking, a “real-time” promotional offer is a promotional offer that may be triggered by a customer's shopping activity, and thus, may be a customer specific promotional offer. A “real-time” offer would typically be presented to such customer while engaging in such shopping activity. For example, if a customer is viewing product Y or places product Y in a shopping cart, using the disclosed technology a remote party (such as a manufacturer or retailer) may detect such customer activity and offer the customer a discount for purchasing product Z where such discount is conditional on a purchase of product Y. Real-time promotional offers would typically be presented to the customer before the customer ends his shopping experience and ideally at a “point of decision.”
• Radio Frequency Identification Devices and associated systems are well suited for SCM applications in general and promotional offering systems in particular. RFID systems may include low-cost, passive “smart” chips or “tags” that can be embedded in or attached to articles, products, and the like to convey information about the product via a scanner. Smart tags are generally small label-like devices with a micro-chip and a miniature embedded antenna. Such tags may be passive or active, the active tags requiring an internal power supply. A reader or scanner interrogates the smart tag with an electronic “trigger” signal. The smart tag in turn generates an electromagnetic pulse response that is readable by the scanner, the response containing the product information. RFID smart tags can be associated with a product by being embedded in or attached to product packaging, or incorporated directly into the product, and may convey conventional “bar code” information, as well as other more detailed information.
• Such RFIDs and associated systems provide the ability to reliably and automatically obtain real-time product information for individual products throughout the supply chain. For example, RFID systems can provide retailers and manufactures real-time product information relating to products a customer is examining or has indicated an intention to purchase by placing such products in a shopping cart. Using RFID technology, retailers and manufacturers may provide real time product information and promotional offerings to a customer while the customer is shopping.
• Exemplary embodiments of the disclosed methodology and system may include a manufacturer computer and database associated with a manufacturing location and a retailer computer and database associated with a particular retail store. The smart tags may be associated with a product at the manufacturing facility and coded with product information, such as the name of the product, type or category of product, manufacturer of the product, an electronic product code (EPC) and so forth. RFID Smart Tag Readers (STR) may be made available at various points along the supply chain in a number of conceivable scenarios according to the invention. Such RFID STR devices may be configured to interrogate RFID smart tags to obtain the information stored in such tags. The RFID STR devices may also be configured to use various techniques for ascertaining the RFID smart tag location. The RFID STR devices may then transfer such information to another electronic device, such as a computer. The electronic device may then use such product information to ascertain any promotional offers, such as cross-marketing coupons, that may be applicable to the product and transfer such information to a customer interface.
• In one particular embodiment of the system and methodology according to the invention, the smart tags are associated with each distinct product, preferably at the place of manufacture. The smart tags may be in the form of adhesive labels or the like that may be attached directly to the product packaging, or to a separate container that holds the product. The RFID tagged products are then placed in customer display inventory locations. Exemplary customer display inventory locations include store shelves, refrigeration units, store cabinets, etc., wherever products are located for customer viewing. RFID tagged products may also be placed in retailer storage inventory locations. One well known exemplary retailer storage inventory location is the in-store stock room.
• For this embodiment, at least one RFID STR device is provided in communication range of each distinct product. For example, one RFID STR device can be moved throughout the retailer store covering all the customer display inventory locations and retailer storage inventory locations. Similarly, an array of RFID STR devices can be moved throughout the retailer store. In the alternative, an array of fixed RFID STR devices can be used. An RFID STR device may comprise a simple transmitter that transmits smart tag “trigger” signals. An RFID STR device may comprise both a transmitter for transmitting “trigger” signals and a receiver for detecting and receiving smart tag transmissions.
• The RFID STR devices may be configured to communicate with a central computer and its associated hardware and software. Such a central computer is preferably located at the retailer store (retailer central computer) but may also be a customer interface or any other suitable electronic device used for data processing.
• Additionally, an RFID STR device may be associated with a “smart cart.” A “smart cart” is a container, such as a shopping cart, that incorporates an electronic computing device and may be used by a customer while shopping to store items the customer anticipates purchasing. Such a smart cart may comprise, for example, a computing device, a display, an RFID STR and a scale. Such devices may be individual components cooperatively connected through wired or wireless connections or integrated into a single electric device. For example, a smart cart computer, a smart cart display and a smart cart RFID STR may be integrated into a single electronic component and referred to collectively as a customer interface.
• One exemplary embodiment of a customer interface is an electronic device comprising a processor, memory and an LCD screen and is preferably located on a shopping cart or other similar apparatus traditionally used by customers while shopping.
• The customer interface is configured to receive a customer request for a desired product and transmit such request to a central computer. The central computer may then access an associated database for product information or request an RFID STR device to provide product information on the requested item. The central computer receives the product information from the RFID STR device (such as inventory count and product location) and transfers at least part of such information to the customer interface. Alternatively, the customer interface may communicate directly with the RFID STR device or an RFID STR device may be incorporated in the customer interface. Such product information may include information on promotional offers that may be related to items in said smart cart or items being viewed by a customer near said smart cart. With this configuration, the central computer (or smart cart computer) will automatically notify the customer of a qualifying promotional offer, such as a cross-marketing offer, and determine when the customer accepts such promotional offer and automatically process accepted promotional offers.
• Another embodiment of the system and methodology according to the invention, relates to a smart cart using smart tag technology to facilitate automatic customer check-outs. Such a smart cart may include a customer-storage-area. Such customer-storage-area may be used to hold products while a customer is shopping. The smart cart further includes a smart-cart-scale. In one exemplary embodiment, such smart-cart-scale provides the surface upon which products are placed when in the customer-storage-area. The smart cart further includes an electronic tag reading device configured to retrieve product information from electronic tags associated with products. Such electronic tag reading device may be a simple reader that only receives electronic tag transmissions and does not transmit an electronic tag trigger signal. Alternatively, such electronic tag reading device may be configured to transmit an electronic tag trigger signal.
• The electronic tag transmissions comprise product information associated with a “hot-product.” A “hot-product” is a product that a customer is presently examining or a product that a customer has placed in the customer-storage-area. The smart cart may be further configured to communicate with a remote computer and to retrieve supplemental-product-information associated with the hot-product. Such supplemental-product-information may be retrieved using the product information retrieved from the electronic tag associated with a hot-product. Generally speaking, supplemental-product-information is any information associated with a product that is not part of the product information stored in the product's electronic tag. Such supplemental-product-information may comprise, for example, cross-marketing promotional offers, expected product weight values, product descriptions, product location within the retailer store and other such information. Exemplary promotional information includes information relating to cross-marketing promotional offers wherein such offers may be real-time promotional offers or near real-time promotional offers. A near real-time promotional offer is a customer generic offer that was generated recently, perhaps at the beginning of the shopping day, but generally after a product has been shipped by a manufacturer to a retailer.
• The smart cart computer is further configured to present product information and supplemental-product-information to the customer. Ideally, the smart cart computer is in wired or wireless communication with the smart-cart-scale. Suitable wireless technologies are well known in the art and include Wi-Fi (wireless fidelity) and Bluetooth. With such a configuration, the smart cart computer can obtain a total-measured-weight of the product or products on the smart-cart-scale and compare such total-measured-weight to the expected-total-weight. If the measured-weight is within a predefined weight-tolerance of the expected-weight, there is an increased confidence that all products on the smart-cart scale are associated with operable and correctly programmed electronic tags.
• Still further embodiments of the present invention relate to methodologies for presenting customers with real-time and near real-time cross-marketing promotional offers. For this exemplary embodiment, electronic smart tags are associated with products. Such products may be placed in retailer display locations, such as customer display inventory locations. As customers are shopping in a retailer establishment, electronic tags associated with “hot-products” are scanned to retrieve the product information stored in such electronic tags. As mentioned above, hot-products are products being examined by a customer or products that have been placed in a customer-storage-area. The product information retrieved from the hot-products is then used to determine if there are any cross-marketing promotional incentives associates with the hot products related to the purchase of a second product. Next the customer is automatically notified of such cross-marketing promotional offers and offered an opportunity to accept such offer. When the customer arrives at a point of sale to purchase the hot-products (i.e. the customer checks-out), the appropriate check-out adjustments consistent with accepted promotional offers are automatically calculated. Such promotional offers may be transmitted to a customer-interface associated with a shopping cart where the offers are displayed for customer viewing. Promotional offers may also be presented to customer via a voice message using, for example, hypersonic technology. Such promotional offers may also be displayed on a display associated with a smart shelf where the promotional offer is displayed when a customer passes near a second product qualifying for a cross-marketing discount (as determined based on the products already in customer storage).
• Yet another exemplary embodiment of the present invention relates to a method for automatic customer check-outs. For this method, electronic smart tags are associated with products and such products are placed in a retailer inventory location for customer viewing while shopping. Each distinct product is associated with at least one smart tag, where such smart tags contain product-information relating to their respective product. Next, the electronic tags associated with hot-products are scanned with an electronic tag scanner to retrieve product information relating to the hot-products being purchased. Such product information is used to determine the expected weight of such hot-products and the price of such hot-products. The expected weight and pricing information may be contained in the product information retrieved form the electronic tags. Alternatively, the product information may be used to access a remote database to retrieve the necessary weight and pricing information. Next the measured weight of the hot-products being purchased is determined. If the measured weight of the hot-products is within a predefined expected weight for such hot-products, the customer is notified of a valid automatic check-out. Otherwise, a message may be transmitted to a retailer customer care representative requesting assistance with the check-out process.
• Also included in such method is automatically adjusting the sales price to allow for qualifying promotional offerings. It should be noted that the step of using said product-information to determine the price of hot-products includes the steps of retrieving information relating to promotional offers associated with the hot-products being purchased and automatically adjusting the purchase price of such hot-products consistent with the terms of the promotional offer(s).
• Additionally, the step of determining the weight of the hot-products may be performed by weighing all hot-products at the same time while on a scale associated with said customer-storage-area. Similarly, the smart tags associated with the hot-products may be simultaneously scanned or substantially simultaneously scanned. Methods for receiving multiple smart tag transmissions and avoiding data transfer “collisions” are well known by those skilled in the art.
• Alternatively, the weight of said hot-products may be determined singularly and electronic tags scanned singularly at a point-of-sale check-out-station. Such hot-products may also be weighed at the same time and smart tags scanned at the same time while such products are on a scale associated with said check-out-station. As before, the customer is automatically notified when the check-out process has been validated and payment is requested. The customer would ideally tender payment using well known technology such as a credit/debit card reader thereby completing an automatic check-out process.
• Additional embodiments of the present subject matter, not necessarily expressed in this summarized section, may include and incorporate various combinations of aspects of features or parts referenced in the summarized objectives above, and/or features or components as otherwise discussed in this application.
• Those of ordinary skill in the art will better appreciate the features and aspects of such embodiments, and others, upon review of the remainder of the specification.

• Reference will now be made in detail to one or more embodiments of the invention, examples of which are graphically illustrated in the drawings. Each example and embodiment are provided by way of explanation of the invention, and not meant as a limitation of the invention. For example, features illustrated or described as part of one embodiment may be utilized with another embodiment to yield still a further embodiment. It is intended that the present invention include these and other modifications and variations.
• FIG. 1 is a block diagram illustration of an exemplary RFID based promotional offering system, or simplysystem10, depicting various components of a supply chain in accordance with the present invention.Exemplary system10 represents a retail supply chain for any type of product and includes a manufacturingcentral computer12 associated with amanufacturing database14 and a retailercentral computer20 associated with aretailer database22, all interconnected via a standard wired and/orwireless communication link24. It should be appreciated that manufacturingcentral computer12 and retailercentral computer20 may be connected to a common database without departing from the scope of the disclosed technology and methodology. For example,manufacturer database14 andretailer database22 may be incorporated into a single database.
• RFID STR30 represents one or more smart tag readers (sometimes referred to as RFID scanners) of conventional design and are used to retrieve the information contained in RFID smart tags.RFID STR30 is one possible embodiment of an electronic tag reading devices that may, for example, comprise an RF transmitter and receiver and an antenna to communicate with RFID transponders, such as RFID smart tags. Such RFID STR devices may include a microprocessor and software programs for this purpose. Exemplary readers include Matrics® Advanced Readers manufactured by Matrics, Inc. (Columbia, Md.), Alien Technology (Morgan Hill, Calif.), or Philips Semiconductor (Eindhoven, The Netherlands). Another example of an RFID STR device is an RFID reader manufactured by Antenova Ltd. (Cambridge, England) or Bancolini B30 handheld RFID Scanner manufactured by Bancolini (Bologna, Italy).
• RFID STR30 may be accessed throughRFID STR interface52. Such RFID STR interface may be, for example, a standard PC or PDA device incorporating a digital interface designed to facilitate communication between RFID STR devices and a computing device connected to wired orwireless communication link24.RFID STR interface52 may comprise a gateway for connecting two otherwise incompatible systems or for simply providing a connection between two compatible systems.RFID STR Interface52 may also be incorporated into retailercentral computer20.Communication link56 may provide a wired or wireless connection fromRFID STR Interface52 tocommunications link24.
• RFID Smart Tag Reader (STR)30 represents one or more RFID STR devices disposed at various locations withinretailer store21. To facilitate remote access to such RFID STR device(s), a networking system, such as a local area network (LAN), may be utilized. In one embodiment,such RFID STR30 device incorporates a TCP/IP protocol suite and an HTTP (HyperText Transfer Protocol) server to provide two-way access to theRFID STR30 data. Such TCP/IP protocols and HTTP server technology are well known in the art. For such an embodiment, theRFID STR30 device(s) include an HTTP server and a TCP/IP protocol stack. TheRFID STR interface52 may provide a gateway (between computers connected to communications link24 and RFID STR30) which ideally enables continuous remote access to theRFID STR30 devices. A gateway is an electronic device that connects two otherwise incompatible systems or that simply provides a connection between two compatible systems.
• Alternatively, the TCP/IP protocol suite may be incorporated into a gateway serving multiple RFID STR devices via a wired or wireless two-way network. The gateway may incorporate an HTTP server for accessing data from multiple RFID STR devices and for transmission of data to individual RFID STR devices.
• In the above describedsystem10 configuration, communications link24 provides access to a first network (such as the Internet) operating in accordance with a predetermined protocol (TCP/IP is one example). A plurality ofRFID STR30 devices may comprise a second network. A gateway (RFID STR Interface52) operatively couples the first network to the second network. Finally, an HTTP server is embedded in either the gateway or the plurality of RFID STR devices facilitating the transfer of data between the two networks. With such a configuration, one of ordinary skill in the art will appreciate that individual RFID STR devices or groups of RFID STR devices may be accessed as if the STR devices were a web site and their information could be displayed on a web browser.
• Such technology is fully disclosed by Ardalan et al. in U.S. Pat. No. 6,363,057 for use in a system for communicating with electricity meters, which is hereby incorporated by reference for all purposes.
• As noted above,RFID STR30 represents one or more RFID STR devices located at aretailer storage inventory36 andcustomer display inventory38.STR30 is connected toRFID STR interface52 via a wired or wireless communications link54. With such a configuration, manufacturingcentral computer12, retailercentral computer20,user interface58, third-party computer25 and any properly configured computing device connected to communications link24 and may transmit and receive data to and fromRFID STR30 as well as customer-interface62.
• User interface58 represents one or more devices designed for providing access to electronic data systems. Such devices include a computer, a terminal, PDA or any digital device configured for accessing data systems. One ormore user interface58 devices may be located wherever access is required tosystem10.
• Internet link24 is a standard Internet link that typically provides a two way communication link betweensystem10 and networks external tosystem10, although Intranet computers can also be accessed through such a link. For example, potential customers ofretailer store21 may useInternet link24 to shop for products sold by aretailer store21, perhaps by accessing product descriptions stored ondatabase22. Customers may also obtain real-time product inventory data as well as other information related to the retailer's products.
• Still referring toFIG. 1, a block diagram representation of an exemplarysmart cart61 is depicted.Smart cart61 may comprise a customer-interface62 and a smart-cart-scale63.Smart cart61 is a device a customer would use while shopping to store and transport the products the customer anticipates purchasing. Exemplarysmart cart61 provides a customer-storage-area67 (FIG. 2) where the bottom of such customer-storage-area67 comprises an item evaluator, such as smart-cart-scale63. Smart-cart-scale63 is in communication with customer-interface62 via wired orwireless communication link65.
• Smart-cart-scale63 is one possible embodiment of an item-evaluator. An item-evaluator is an electronic device associated with customer-storage area67 and designed to measure a physical parameter, such as weight, of hot-products in customer-storage area67. The general purpose of such an item-evaluator is to provide a means for cross referencing the electronic tag data retrieved from hot products. Such cross referencing provides added confidence that all items are associated with proper electronic tag, that such electronic tags are working properly and that such electronic tags have been programmed properly and/or that the supplemental-product-information associated with hot-products is accurate.
• Customer-interface62 (shownFIG. 1,FIG. 2 andFIG. 4) is an electronic device preferably supplied by the retailer and used by a customer while shopping for products incustomer display inventory38.Customer interface62 may have a conventional hardware and software architectural design suitably adapted for sending messages to and receiving messages from a central computer (such as retailer central computer20) and/or RFID STR devices (such as RFID STR30). Whilecustomer interface62 is portrayed as having a built-invisual display screen64, it should be recognized thatcustomer display62 may comprise a plurality of physically separated but cooperatively associated electronic devices that are not shown independently such as a radiofrequency transmitter and receiver, a processor, one or more display means such as avisual display screen64, a magnetic card reader, an audio speaker, and the like, each communicating with or under control of a central computer, ideallycentral computer20.Customer interface62 may incorporate an alarm or alert feature wherein the customer is notified of special product offerings.Customer interface62 may also comprise an RFID STR device.
• As noted above,smart cart61 comprises a customer-storage-area67 for storing products a customer anticipates purchasing, referred to herein as “hot-products.” Restated, a “hot-product” is a product that a customer is presently examining or a product that a customer has placed in customer-storage-area67.FIG. 2 depicts two hot-products,69aand69b.
• Customer-interface62 may be in communication with a remote computer, such as retailercentral computer20, manufacturercentral computer12,user interface58, third-party computer25 or any properly configured computing device connected tocommunication link24. With this configuration, customer-interface62 may be used to retrieve, from a remote computer, supplemental-product-information associated with hot-products. For example, customer-interface62 may use an associated RFID STR device to retrieve product information from electronic tags associates with exemplary hot-products69aand69b.For this example, such product information comprises a Universal Product Cede (UPC). Customer-interface62 would transmit such product information to a remote computer, such as retailercentral computer20, and request supplemental-product-information. Retailercentral computer20 may respond by transmitting selective supplemental-product-information back to customer-interface62 to be displayed for customer viewing onLCD display64.
• Generally speaking, supplemental-product-information is any information associated with a product that is not part of the product information retrieved from an electronic tag or stored in an electronic tag. Such supplemental-product-information may comprise, for example, cross-marketing promotional offers, expected product weight values, product descriptions, product location within the retailer store and other such information. Exemplary promotional information includes information relating to cross-marketing promotional offers wherein such offers may be real-time promotional offers or near real-time promotional offers. The smart cart computer is further configured to present product information and supplemental-product-information to the customer.
• Ideally, the smart cart computer associated with customer-interface62 is in wired or wireless communication with smart-cart-scale63. Suitable wireless communications technologies are well known in the art, examples of which include Wi-Fi (wireless fidelity) and Bluetooth. With such a configuration, the smart cart computer can obtain a total-measured-weight of the product or products on the smart-cart-scale and compare such total-measured-weight to the expected-total-weight. The smart cart computer would determine the expected-total-weight using product information or supplemental-product-information retrieved fromsmart tags72 or a remote computer respectively. If the total-measured-weight is within a predefined weight-tolerance of the expected-total-weight, there is an increased confidence that all products on the smart-cart scale are associated with operable electronic tags. Conversely, when a product added to the customer-storage-area results in a total-measured-weight that is not within such predefined weight-tolerance of the expected-total-weight, customer-interface62 may issue an alert to the customer.
• For example, assume an exemplary predefined weight-tolerance of 98% of the expected-total-weight. If the expected total weight for 10 products is 100 pounds and the total-measured-weight is only 95 pounds, the smart cart would issue an alert. Such alert may be transmitted to the shopper or to a customer service representative. Such an alert would put the shopper on notice that something associated with the last added product (inoperable smart tag, missing smart tag, incorrect product information, etc.) placed in customer-storage-area67 is faulty and that such product will likely result in a longer check-out time (due to a customer service person having to troubleshoot the problem and/or manually check-out the item). Thus, such an alert gives a customer the opportunity to switch the product with another product (same product type, just in a different package) before proceeding to a point of sale. Anyone who has experienced check-out delays due to bad product labeling associated with prior art check-out systems (i.e. optical bar code systems) will appreciated the value of this feature.
• The above example used a “total expected weight” value and measured the total expected for all the products in customer-storage-area67. It should be appreciated that the smart cart computer could just as easily determine the added additional weight of the last item placed on smart-cart-scale63 and issue an alert when the added weight is not correct. For example, assume for a moment that nine items weighing 90 lbs. are on smart-cart-scale63. A tenth item is placed on smart-cart-scale63 and the total weight goes up to 100 lbs. The smart cart computer may detect that 10 lbs. has been added on top of smart-cart-scale63 and scan the smart tags associated with the items on smart-cart-scale63. The smart cart computer may then receive information for the newly added item including expected weight information for item ten. If the measured weight for item ten is not within a predefined weight tolerance of the expected weight, then the smart cart computer issues an alert. It should be appreciated that both methods use (directly or indirectly) the expected total weight of hot-products.
• Smart cart61 also allows for remote updating of a shopping list. Customer-interface62 ideally allows a customer to establish a communication connection with third-party-computer25 via communications link24. Such a remote communication connection could be established, for example, using an IP address associated with third-party-computer25 and software for facilitating remote communication connections. Examples of such software include Virtual Network Computing (VNC) and Windows Remote Desktop. Alternatively, an instant messaging type connection could be established between customer-interface62 and third-party computer25 allowing a customer to send and receive instant text message, VoIP (Voice Over IP) messages and/or video enabled messages to a person associated with third-party-computer25.
• For example, suppose person A sends person B to a grocery store to purchase products W, X and Y. Person B travels toretailer store21 and acquiressmart cart61. Person B uses customer-interface62 to establish a communication connection with third-party-computer25 which may be monitored by person A. Alternatively, person B could simply log into an instant messaging system. While person B is at the grocery store purchasing products W, X and Y, person A discovers that person A also needs product Z. Using third-party-computer25, person A accesses person B's shopping list and automatically updates the list. Alternatively, person A simply sends person B an instant message informing person B to also purchase product Z. Ideally, such a communication connection would be established automatically when person B enters a customer ID (or scans an ID card, smart card, etc.) into customer-interface62. Additionally, for a video/camera enabled customer-interface62, person B could send a snapshot or video image of a product to person A so that person A can verify that person B has the correct product.
• Again referring toFIG. 2,exemplary retailer products70 stored incustomer display inventory38 are shown. In theFIG. 2 illustrated embodiment, theproducts70 are food products. It should be appreciated that this is for purposes of illustration only. The products may just as well be clothing items, hardware items, and other staple items of commerce. Suchexemplary retailer products70 are provided or associated with respective RFIDsmart tags72. As discussed in greater detail below, thesmart tags72 transmit a codedpulsed signal78 containing product information in response to an electronic “trigger”76 from aSTR30.
• Thesmart tags72 may be attached directly to theproducts70, as illustrated inFIG. 2. In this embodiment, thesmart tags72 may be, for example, adhesive backed labels or tags that are attached directly to the packaging of theproducts70. Alternatively, suchsmart tags72 maybe attached to containers that are specially designed to hold such products. For example, a toothbrush and its associated factory packaging could be placed in a tubular container where asmart tag72 is attached to said tubular container. Such container may be reusable.
• Similarly,system10 according to this embodiment of the invention includes a combination ofsmart tags72 attached directly to the products as well as the location where such products are to be placed on display for customers to view while shopping. For example, asmart tag72 may be attached to both theproducts70 and the shelves containing theproducts70 along with or incorporated with the store's own identification labels.
• In general, as shown inFIG. 2, a differentsmart tag72 is associated with each distinct product. For example, if the retailer carries three different brands of milk, then a different smart tag may be associated with each brand. Similarly, if three different size containers of the same brand of milk are carried by the store, then a differentsmart tag72 may be associated with each different sized container.
• The product identification information stored in thesmart tags72 is not limited in scope, and may include, for example, information identifying the type of product, brand name of product, manufacturer of the product, etc. The type of product information stored insmart tags72 is preferably adequate to correlate with various manners of listing desired products. For example, certain customers may only list “milk” and “butter” in a generic sense in their respective lists of desired products. Different customers may identify the milk and butter by a particular brand name. The stored product identification information should be adequate to assimilate all reasonably conceivable methods of listing desired products.
• With conventional RFID “smart” systems, thesmart tags72 are passive devices. As shown inFIG. 2,RFID STR30 emits atrigger excitation signal76 received by an internal antenna in thesmart tag72. Thissignal76 causes thesmart tag72 to generate and transmitsignal78, an electromagnetic pulse of coded digital data containing the product identification information. The codedsignal78 is received by the RFID STR30 (or customer-interface62), decoded, and the product identification information is presented to retailercentral computer20, in any number of ways. Retailercentral computer20 may then transfer any relevant product information to customer-interface62.
• RFID smart tag technology is known and understood by those skilled in the art, and a detailed explanation thereof is not necessary for purposes of describing the method and system according to the present invention. Generally, conductive or passivesmart tags72 consist of silicon or other semiconductors, a coiled, etched, or stamped antenna, a capacitor, and a substrate on which the components are mounted or embedded. A protective covering is typically used to encapsulate and seal the substrate. Inductive or passive smart tags have been introduced by Motorola under the name “BiStatix.” A detailed description of the BiStatix device may be found in U.S. Pat. No. 6,259,367 B1, incorporated herein by reference in its entirety for all purposes. Another commercial source of suitable smart tags is Alien Technology Corporation of Morgan Hill, Calif., under the technology name FSA (Fluidic Self-Assembly). With the FSA process, tiny semiconductor devices are assembled into rolls of flexible plastic. The resulting “smart” substrate can be attached or embedded in a variety of surfaces. The smart tag technology under development at the Auto-ID Center at Massachusetts Institute of Technology (Cambridge, Mass.) can also be used within the scope of the present invention. Further information on smart tags and related technology is disclosed in U.S. Pat. No. 6,451,154, “RFID Manufacturing Concepts,” issued Sep. 17, 2002 to Grabau et al.; U.S. Pat. No. 6,354,493, “System and Method for Finding a Specific RFID Tagged Article Located in a Plurality of RFID Tagged Articles,” issued Mar. 12, 2002 to Mon; PCT publication WO 02/48955, published Jun. 20, 2002; U.S. Pat.

• Other RFID technologies believed to be of value for the present invention include those produced by Microchip Technologies (Chandler, Ariz.), which provides remote read-write chips at several frequencies. Also of potential value are the I*CODE chips and readers of Philips Semiconductor (Eindhoven, The Netherlands), which, in one embodiment, are said to include 384 bit configurable read/write memory with 64 bits for a unique serial number (e.g., an electronic product code). Sokymat (Lausanne, Switzerland) markets the PICCOLO read-only RFID disc tag which transmits data to a reader station by an AM radio signal. The tag is said to have 64 bits of data that can be programmed during manufacture by laser fusing of polysilicon links in order to store a unique code on each tag.
• Texas Instruments (Dallas, Tex.) offers RFID technology as part of Texas Instruments RFID (TI*RFID™) Systems, formerly known as the TIRIS™ system (Texas Instruments Registration and Identification System), which is used to track and identify various assets using devices such as the TI Tag It™ chip.
• Gemplus (Gemenos, France) provides smart tags (sometimes called “smart labels”) and smart cards employing RFID technology, which may be used as smart tags. They also market interfaces, antennas, scanners and software that can be adapted for use with smart tags.
• Nedap (Groenlo, The Netherlands) provides smart cards and a 13.56 MHz smart tag using RFID technology with 512 bits of read-write memory with a range of about 120 cm. It is claimed that about 20 such tags per second can be read successfully by a scanner.
• Checkpoint Systems Inc. (Miami, Fla.) offers a smart tag with WORM technology (write once, read many). One example is the MCRF355 chip, described more fully at www.idsystems.com/reader/1999_—05/join0599.htm.
• PDA-like reader systems and other portable readers for RFID technology are marketed by Omron Company (Tokyo, Japan), such as the Model V700 or V720 series.
• High frequency bands can be used in RFID technology, such as bands between 300 MHz and 10 GHz. SCS Corporation (Rancho Bernardo, Calif.), for example, markets smart tag technology at 2.45 GHz. Ultra-wide band technology can also be adapted for RFID systems.
• A related technology within the scope of the present invention is Surface Acoustic Wave (SAW) technology. For example, InfoRay (Cambridge, Mass.) markets a passive smart tag that is said to achieve long ranges (up to 30 meters) using a Surface Acoustic Wave (SAW) device on a chip coupled with an antenna. The SAW device converts a radio signal to an acoustic wave, modulates it with an ID code, then transforms it to another radio signal that is emitted by the smart tag and read by a scanner. The ID code of the smart tag is extracted from the radio signal. The scanner is said to compare the spectral content of the signal with a database of signatures to derive the ID code. This method enables a read range of up to 30 m (typical 10-20 m). The system can operate in the 915 MHz band and 2.45 GHz band. RFSAW, Inc. (Dallas, Tex.) also provides minute Surface Acoustic Wave (SAW) RFID devices that can be used within the scope of the present invention.
• The antenna embedded within thesmart tags72 is generally one component of the device, though it is recognized that alternatives to antennas may exist in some applications. For example, for some metallic objects, the smart tag need not comprise an antenna but the metallic object itself can serve as the antenna. Theexcitation signal76 from theRFID STR30 can be received by the antenna to “activate” the smart tag. The receivedexcitation signal76 is the power source for thesmart tag72 and results in the generation of the electromagnetic pulse containing the coded productidentification information signal78. A detailed description of RFID smart tag antennas may be found in U.S. Pat. No. 6,320,556 B1, incorporated herein by reference for all purposes.
• In an alternate embodiment, thesmart tags72 may be active devices. In this configuration, thesmart tag72 includes active transceiving circuitry that has the capability to selectively respond to coded request signals transmitted by anRFID STR30. The activesmart tag72 may include the capability to delete its fixed code and receive new or additional information beyond the information contained in its fixed code. An activesmart tag72 requires an internal power supply, such as a micro-battery, thin film battery, or the like.Active tags72 may be desired in the scenarios wherein thetags72 are mounted at storage locations of particular products. In this way, as different products are stored at the respective locations, thesmart tags72 can be programmed accordingly.
• Referring now toFIG. 3, a point of sale comprising an automatic check-out-station80 is presented. Check-out-station80 comprises check-outcomputer85,card reader89,scale82, an electronic tag reader (not shown) incorporated in check-outcomputer85 and a legacy opticalbar code scanner87. Check-outcomputer85 is in communication withcard reader89,scale82 and opticalbar code scanner87. Check-outcomputer85 may also be in communication with retailercentral computer20 and/or manufacturercentral computer12 viacommunication link24 or any other suitable communication link. Hot-products91-95 are placed onscale82 allowing check-outcomputer85 to determine a total-measured-weight for such hot-products. Check-outcomputer85 uses an electronic tag scanner to retrieve product information stored inelectronic tags72 associated with hot-products91-95. Check-outcomputer85 may also obtain supplemental-product-information for hot-products91-95 from a remote computer, such as retailercentral computer20 and/or manufacturercentral computer12. Using at least part of the retrieved product information and/or supplemental-product-information, check-outcomputer85 determines the total sales price for hot-products91-95 automatically adjusting the total sales price to compensate for qualifying promotional offers, such as cross-marketing offers.
• For example, suppose manufacturer X offers a cross-marketing promotional offer that reduces the price of hot-product93 by 10% when a customer purchases hot-product92. When a customer places hot-product92 and hot-product93 onscale82, check-outcomputer85 scans theelectronic tags72 associated with hot-products92 and93, retrieves product information and/or supplemental-product-information for hot-products92 and93, determines that a qualifying cross-marketing promotional offer has been accepted and automatically reduces the sales price for hot-product93 by 10%.
• FIG. 4 presents one exemplary embodiment of an automatic check-out station used in conjunction withsmart cart61. To initiate the automatic check-out process, a customer placessmart cart61 withinarea96. Automatic check-out-station81 may automatically detect the presence ofsmart cart61 inarea96 or a customer may initiate the automatic check-out process using check-outcomputer85 and performing the appropriate function (such as pushing a “start automatic check-out button”). Check-outcomputer85 may then access customer-interface62 and validate the product information associated with hot-product91 as well as the measured hot-product91 weight information. If such information is deemed acceptable, check-outcomputer85 validates the automatic check-out and the customer is presented with a total purchase price and payment is requested. Such customer may then “swipe” a credit card, debit card or other suitable card throughcard reader89 to pay the total purchase price. As before, the total purchase price has been automatically adjusted to account for any qualifying promotional offers, such as cross-marketing promotional-offers.
• Examples of methodologies for usingsystem10 are now discussed.FIG. 5 is a high level block diagram depicting exemplary logic for a Main Cross-Marketing & Automatic Check-out (CMAC) routine. Main CMAC routine is preferably implemented in software executed by a computer associated retailercentral computer20 or customer-interface62. It should be appreciated, however, that any computer with access to communications link24 may be the computer executing the CMAC routine and hereafter such computer will simply be referred to as the “computer.” Step100 marks the entry point into the exemplary CMAC routine shown inFIG. 5. Atstep102, the computer waits for a product-information retrieval triggering event. Exemplary product-information triggering events ideally coincide with “points of purchasing decision.” Examples of “points of purchasing decisions” include: (1) the moments when a customer is viewing a product while shopping, (2) the entire time while shopping for products that have been placed in a customer storage area, (3) the moments at a point of sale (the check-out station) and (4) the moments while responding to a customer request for data about a product. Thus, exemplary product-information retrieval triggering events include: (1) a customer picking up a product, (2) a customer placing a product in a customer storage area, (3) a customer presenting at product at a point of sale for purchase, (4) a customer request for product information. The products that trigger the above-described product-information retrieval process are hereafter referred to as “hot-products.” Upon detecting a triggering event, the computer retrieves product information stored in electronic tags associated with such hot-products (step104). Additionally, the computer may access supplemental-product-information using such retrieved product information. With such information, atstep106, the computer determines if a cross-marketing (CM) promotional offer is associated with the hot-product(s). If no cross-marketing promotional offer is associated with the hot-product(s), program control passes to step114. If, however, a cross-marketing promotional offer is associated with the hot-product(s), the computer presents the cross-marking promotional offer to the customer (step108). Such information may be presented, for example, using an LCD and/or speaker associated with a customer interface, such ascustomer interface62. Such information would typically include a description of the second item for which the customer will receive a reduced price if such customer purchases the hot-product. Such information may also include in-store location information to assist the customer in locating the second item.
• Atstep110, the computer determines if the customer accepts the cross-marketing promotional offer. Step110 may be accomplished by requesting the customer to respond to a computer generated question and detecting/recording the customer response. For example, the computer may transmit cross-marketing promotional offer information and then present the following: “If you accept this offer, please press 1.”
• Alternatively, detecting acceptance of the cross-marketing offer may simply comprise determining if the second item is added to a customer display inventory location. Using this method,step110 and112 may be skipped (i.e. program control passes directly fromstep108 to step114) and/or performed later. Atstep114, the computer detects when a customer has arrived at a point-of-sale and executes the exemplary “POS Check-out” routine.
• Point120 marks the entry into an exemplary point of sale (POS) check-out routine. Atsteps122, the computer determines if an automatic check-out is desired. If an automatic check-out is not desired, program control passes to step124 and the typical, well known manual check-out process is begun where a retailer employee scans the hot-products. However, even with such manual check-outs, benefits of the disclosed invention can still be leveraged. Atstep124, electronic tags associated with hot-products are scanned and at least part of the product information stored in such tags is retrieved. With this information, the computer may acquire supplemental-product-information. The computer then automatically determines if there are any qualifying promotional offers associated with the hot-products and the sales price is automatically adjusted as required. Atstep128 the shopper is presented with the bill and payment is requested.
• If atstep122 an automatic check-out is desired, program controls passes to step130 and an exemplary Automatic Check-out routine is executed. Step140 marks entry into an Automatic Check-Out routine. Atstep142, the computer determines if the smart-cart information is to be used. The results ofstep142 may be determined by the smart-cart configuration, the status of the smart-cart or other considerations. For example, if the smart-cart does not have an operable scale, then the smart-cart weight info cannot be used. Although it should be appreciated that the smart-cart pricing information could still be used.
• If atstep142 the computer determines that the smart-cart info is to be used, atstep146 the hot-product's weight information and smart tag information is verified by rescanning the electronic tags associated with the hot-product(s) and reacquiring the weight of the hot-product(s). Alternatively, previously acquired electronic tag and weight data may be used (no rescanning or reweighing).
• If the hot-product's weight and electronic tag information are acceptable, a valid automatic check-out has been deemed achieved (i.e. “BAD Smart-Cart Info” flag will not be set) and program control passes back to the calling routine. If, however, atstep148 the smart-cart weight and/or electronic tag information for the hot-product(s) are not acceptable, then a “Bad Smart-Cart Info” flag is set and program control jumps back to the calling routine (i.e. the POS Check-out routine).
• Returning to step142, if for some reason the smart-cart check-out information can not be entirely used (for example, no scale or bad scale), a different semi-automatic self check-out process can be utilized. Atstep150, the computer asks the customer to remove a hot-product from a customer storage area and place such hot-product on, or move such hot-product close to, a check-out station scanner. Atstep152, the electronic tags associated with such hot-product are scanned and relevant hot-product information is retrieved as before. Next, atstep153, the weight of the product is acquired. The measured weight and the expected weight is compared and, atstep154, if the weight is OK, program control passes to step156 to determine if the last item has been scanned. If the last item has been scanned program control simply passes back to the calling program (i.e. the POS Check-out routine). If atstep156 the computer determines that the last item has not been scanned, program control jumps back tostep150.
• If atstep154 the hot-product weight is not acceptable, then a “Bad Smart-Cart Info” flag is set and program controls returns to the calling program.
• Upon returning to the POS Check-out routine from the Automatic Check-out routine, program control passes to step132. If the “Bad Smart-Cart Info” flag is set, a customer service person is notified of an invalid smart-cart information condition (step134). Otherwise, program control passes to step128 where the customer is presented with the bill and payment is collected.
• While the present subject matter has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing may readily adapt the present technology for alterations to, variations of, and equivalents to such embodiments. Accordingly, the scope of the present disclosure is by way of example rather than by way of limitation, and the subject disclosure does not preclude inclusion of such modifications, variations, and/or additions to the present subject matter as would be readily apparent to one of ordinary skill in the art.
• It should also be appreciated that the system and method according to the invention are not limited to any particular type of commercial or market scenario, but have application wherever customer goods or products are typically purchased.
