Description

CROSS-REFERENCE TO RELATED APPLICATIONS
• This application is based upon and claims the benefit of priority from prior Japanese Patent Applications No. 2006-143074, filed May 23, 2006; and No. 2006-143075, filed May 23, 2006, the entire contents of both of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
• 1. Field of the Invention
• The present invention relates to a portable terminal, programs for use in the terminal, a settlement apparatus that can perform data communication with the terminal, and a MERCHANDISING-information providing apparatus.
• 2. Description of the Related Art
• Cellular telephones developed in recent years incorporate an external wireless interface that achieves wireless communication by using infrared rays, a non-contact IC card or the like. Settlement applications are now proposed, which enable a telephone user to pay charges and receive coupons by using the wireless interface.
• Particularly, it is proposed that shops should electronically input receipts into the cellular telephone when the telephone user pays for whatever he or she has just bought. If the receipts are recorded in the form of electronic data, the user can have his or her household account book kept both electronically and automatically. This is advantageous to the telephone user. This is useful to the shops, too, because the expense involved in issuing paper receipts is saved. In view of this, it is well expected that the electronic-receipt issuing technology will soon come into use.
• The amount of data that can be recorded on electronic receipts is almost limitless, unlike the amount of data recordable on conventional paper receipts. If shops issue electronic receipts, they can give the consumers far more merchandise and advertisement information than by issuing conventional paper receipts.
• Jpn. Pat. Appln. KOKAI Publication No. 2005-141649, for example, discloses a technique of adding additional information to electronic receipts. In this technique, an electronic receipt with additional information is transferred to the purchaser's personal computer, and the personal computer records the information in the household account book. The purchaser can therefore review the additional information on the personal computer.
• Thus, this technique enables the purchaser to review, on his or her personal computer, the additional information recorded on the electronic receipt. Most personal computers are unusable outdoors. Inevitably, consumers can access such value-added information only indoors. Assume that the merchandise bought is one for outdoor use and that the additional information (i.e., merchandise information) is instructions for solving problems with the merchandise. Then, the purchaser cannot access the information immediately while he or she is using the merchandise in the open.
BRIEF SUMMARY OF THE INVENTION
• An object of the present invention is to provide a portable terminal on which the information contained in electronic receipts can be easily reviewed, even in the open, and a system that enables the user of the terminal to review the information.
• According to an aspect of this invention, there is provided a portable terminal that comprises: a communications unit which communicates with an electronic-receipt server and a communications unit which communicates with a settlement-processing apparatus. On receiving simplified settlement data generated form settlement data and ID data for downloading electronic-receipt data from an electronic-receipt server, both from a settlement-processing apparatus, the portable terminal records the simplified settlement data in association with the ID data. The display unit of the portable terminal displays the simplified settlement data thus recorded.
• The portable terminal downloads electronic-receipt data from the electronic-receipt server by using the ID data recorded in association with the simplified settlement data, when the input unit is operated, thereby commanding that the electronic receipt related to the simplified settlement data displayed by the display unit should be downloaded. The electronic-receipt data is recorded in the electronic-receipt recording unit. The display unit displays the electronic receipt on the basis the electronic-receipt data recorded in the electronic-receipt recording unit.
• Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

• How theportable terminal8 performs electronic settlement will be explained with reference toFIG. 7.
• To make electronic settlement, the purchaser operates theinput unit18 provided on his or herportable terminal8, activating the electronic settlement program P1. On the other hand, the cashier operates thePOS terminal2, registering the sales data concerning the merchandise the customer (i.e., purchaser) has bought, into thePOS terminal2. On registering the sales data, the cashier asks the purchaser to pay for the merchandise. So requested, the purchaser moves theportable terminal8 toward thePOS terminal2, setting thecommunications interface15 at a position close to thecommunications interface26 of thePOS terminal2.
• Since the electronic settlement program P1 has been activated, the CPU11 of theportable terminal8 monitors the communications interface15 (Step S101). When theportable terminal8 is moved near thePOS terminal2, thecommunications interface15 starts communication with thecommunications interface26 of thePOS terminal2. At this point, the CPU11 sends a request for electronic settlement to thePOS terminal2 via the communications interface15 (Step S102).
• In response to this request, thePOS terminal2 performs electronic settlement with theportable terminal8. When the electronic settlement is completed, thePOS terminal2 generates ID data for downloading electronic-receipt data from an electronic-receipt server6 and simplified settlement data. The ID data and the simplified settlement data are transmitted from thecommunications interface26 to theportable terminal8. The ID data is information that is used to download the electronic receipt that has been uploaded fromPOS terminal2 into the electronic-receipt server6. The simplified settlement data is data extracted from the settlement data that is recorded on the electronic receipt.
• In theportable terminal8, the CPU11 receives, via thecommunication interface15, the ID data for downloading electronic-receipt data from an electronic-receipt server6 and simplified settlement data transmitted from the POS terminal2 (Step S103). The CPU11 associates the ID data and the simplified settlement data with each other and then stores them into the non-contact IC card memory27 (Step S104). Thereafter, the CPU11 activates the electronic settlement program P2 (Step S105).
• How theportable terminal8 operates after the electronic-receipt processing program P2 has been activated will be explained, with reference toFIG. 8.
• In theportable terminal8 with the electronic-receipt processing program P2 activated, the CPU11 determines whether the non-contactIC card memory16 stores simplified settlement data (Step S201). If thememory16 stores the simplified settlement data, the CPU11 makes thedisplay unit17 display the simplified settlement data (Step S202).
• Next, the CPU11 causes thedisplay unit17 to display a message asking the user whether the program P2 should be terminated and waits for an input from the user (Step S203). If the user inputs a command for terminating the program P2, the CPU11 terminates the electronic-receipt processing program P2.
• If the user inputs a command for keeping the activation of the program P2, the CPU11 makes thedisplay unit17 display a message asking the user whether the electronic receipt corresponding to the simplified settlement data should be downloaded and then waits for an input from the user (Step S204).
• If the user inputs a command for downloading the electronic receipt, the CPU11 decodes the ID data stored in association with the simplified settlement data, thereby generating an URL that will be used to download the electronic receipt. Using the URL thus generated, the CPU11 connects the public-network interface14 to the Internet5 (Step S205).
• The URL represents the address of the electronic-receipt managing area43aprovided in the electronic-receipt server6, in which the electronic-receipt information has been uploaded from thePOS terminal2. The CPU11 downloads the electronic-receipt information from the address (Step S206). The information thus downloaded is temporarily stored in thememory12.
• The CPU11 analyzes the electronic-receipt information thus downloaded and makes thedisplay unit17 display the electronic receipt represented by this information (Step S207). The CPU11 then waits for a confirmation from the user (Step S208).
• When the user input a confirmation, the CPU11 makes thedisplay unit17 display a message asking the user whether the electronic receipt should be stored in the portable terminal8 (Step S209) and waits for an input from the user (Step S210). Upon receiving of the user input indicating that electronic receipt should be stored, the CPU11 records the electronic-receipt information in the recording unit13 (Step S211). The CPU11 then erases the electronic-receipt information from the temporary memory12 (Step S212).
• Next, the CPU11 records the ID data and the simplified settlement data, both used to download the electronic receipt, in therecording unit13 in association with the electronic-receipt information (Step S213). Alternatively, only the simplified settlement data may be recorded in association with the electronic-receipt information.
• Thereafter, the CPU11 erases the ID data and the simplified settlement data, both used to download the electronic receipt, from the non-contact IC card memory16 (Step S214). The operation then returns to the first step.
• How thePOS terminal2 operates after the electronic-receipt processing program P5 has been activated will be explained, with reference toFIG. 9. In thePOS terminal2, the electronic-settlement program P5 is activated when the information about the merchandise the customer (i.e., user of the portable terminal8) has bought.
• In thePOS terminal2 with the electronic-settlement program P5 activated, theCPU21 waits for a request for electronic settlement coming from theportable terminal8 via the communications interface26 (Step S301). A request for electronic settlement may come after the information concerning the merchandise has been registered. In this case, theCPU21 performs the electronic settlement on the basis of the information concerning the merchandise (Step S302). Thus, the electronic settlement between thePOS terminal2 and theportable terminal8 is completed (Step S303). Then, theCPU21 activates the electronic-receipt processing program P6.
• How thePOS terminal2, in which the electronic-receipt processing program P6 has been activated, operates will be explained, with reference toFIG. 10.
• In thePOS terminal2 with the electronic-receipt processing program P6 activated, theCPU21 makes thecustomer display unit30 display a message of, for example, “Please keep holding your portable terminal at thePOS terminal2” (Step S401). There is a time lag between the completion of the electronic settlement and the transmission of simplified settlement data to theportable terminal8. Therefore, the ID data and the simplified settlement data, which is required to downloading the electronic receipt, cannot be transmitted if the user moves theportable terminal8 away from thecommunications interface26 of thePOS terminal2 immediately after the electronic settlement is accomplished. If these data items are not transmitted, the electronic receipt will not be transmitted to the electronic-receipt server6. This is why thecustomer display unit30 displays the message, telling the user not to move theportable terminal8 away from thePOS terminal2.
• While thedisplay unit30 is displaying the message, theCPU21 performs a process for generating an electronic receipt and information items related to the receipt. More precisely, theCPU21 extracts, from the merchandise-information managing area23a, the name and price of the merchandise registered at the electronic settlement, the merchandise-information accessing data and the like which should be recorded on the electronic receipt. Using these information items, theCPU21 generates the electronic receipt (Step S402). Further, theCPU21 extracts the data items, such as the date of settlement and the total amount paid for the merchandise, from the information items recorded on the electronic receipt, and generates simplified settlement data from the data items extracted (Step S403). Furthermore, theCPU21 generates ID data which will be later used to download the electronic receipt from the electronic-receipt server6 to the portable terminal8 (Step S404).
• At this point, the data on the electronic receipt and the simplified settlement data are formulated in such as Extensible Markup Language (XML) format as is shown inFIGS. 12 and 13. On the electronic receipt, the merchandise-information accessing data is recorded as href=“http:// . . . ” in tag <merchandise> contained in the XML data (FIG. 12).
• TheCPU21 connects thenetwork interface24 to the LAN4 and theInternet5. The ID data for downloading the electronic receipt and the electronic-receipt information, thus generated, are transmitted from thePOS terminal2 to the electronic-receipt server6 (Step S405). TheCPU21 further transmits the ID data for downloading the electronic receipt and the simplified settlement data to theportable terminal8 via the communications interface26 (Step S406).
• On completing transmission of the ID data and the simplified settlement data to the portable terminal8 (Step S407), theCPU21 causes thedisplay unit30 to stop displaying the message (Step S408). The process of the electronic-receipt processing program P6 is thus completed.
• How the user accesses the merchandise information on the electronic receipt when he or she reviews the electronic receipt displayed on theportable terminal8 will be explained, with reference toFIG. 11 is a flowchart the sequence of major steps of the electronic-receipt reviewing program P3 installed in theportable terminal8.
• The user operates theinput unit18 provided on his or herportable terminal8, thereby activating the electronic-receipt reviewing program P3.
• In theportable terminal8 with the electronic-receipt reviewing program P3 thus activated, the CPU11 makes thedisplay unit17 to display a list of the simplified settlement data items concerning all electronic receipts stored in the recording unit13 (Step S501). The CPU11 then prompts the user to select at least one of the simplified settlement data items.
• FIG. 14 shows some of the simplified settlement data items displayed on thedisplay unit17 at this point. As seen fromFIG. 14, the data items are displayed in the form of a list. The user operates theinput unit18, thus moving the cursor to any desired data item, on the screen of thedisplay unit17. The desired data item is thereby selected.
• The CPU11 determines whether the user has selected any simplified settlement data item (Step S502). If the user has selected a simplified settlement data item, the CPU11 analyzes the XML data on the electronic receipt, which corresponds to the simplified settlement data selected and then makes thedisplay unit17 display the electronic receipt (Step S503).
• FIG. 15 shows the data thedisplay unit17 displays at this time. As seen fromFIG. 15, the electronic receipt is displayed in the same layout as the corresponding paper receipt. The user can select any merchandise displayed on thedisplay unit17, by operating theinput unit18 and moving the cursor to the name of the merchandise displayed on thedisplay unit17.
• The CPU11 determines whether the user has selected any one of item of the merchandise recorded on the electronic receipt (Step S504). If any one item of merchandise has been selected, the CPU11 makes thedisplay unit17 display the menu about the merchandise selected (Step S505). If the input is not concerned with selection of merchandise, the operation returns to Step S502.
• After making thedisplay unit17 display the menu about the merchandise, the CPU11 determines whether the user has selected “review merchandise information,” i.e., one of the menu items (Step S506). If “review merchandise information” has been selected, the CPU11 extracts, from the data recorded on the electronic receipt, merchandise-information access data about the merchandise the user has selected (http://awinecompany.co.jp/forwine) (Step S507).
• Thereafter, the CPU11 activates the merchandise-information-site reviewing program P4. Using the merchandise-information accessing data, the CPU11 accesses the merchandise-information site (i.e., the merchandise-information providing server9) through the Internet5 (Step S508).
• If any item other than “review merchandise information” has been selected, the operation returns to Step S504.
• The merchandise-information providing server9 keeps activating the merchandise-information transmitting program P8 at all times and keeps waiting for an access from theportable terminal8. In the merchandise-information providing server9, theCPU51 receives an access from theportable terminal8. It then transmits the Web page of the merchandise information contained in the URL of the access, to theportable terminal8. At this time thedisplay unit17 of theportable terminal8 displays such data as shown inFIG. 16. This operation is the same as one performed in the ordinary Web server, and will not de described here in detail.
• In the network system of the configuration described above, thePOS terminal2 generates an electronic receipt showing the details of an electronic settlement when thePOS terminal2 at the transaction is settled with the customer at theshop1. The electronic receipt thus generated is transmitted via theInternet5 to the electronic-receipt server6 and is published on Web.
• At this time, the simplified settlement data based on the settlement data and the ID data for downloading the electronic receipt are transmitted from thePOS terminal2 to theportable terminal8. When the customer operates theportable terminal8, demanding that electronic receipt be downloaded, the electronic-receipt information is downloaded from the electronic-receipt server6 into theportable terminal8 in accordance with the ID data.
• Thus, the customer can have the electronic receipt published on Web downloaded into theportable terminal8 that incorporates a Web browser. He or she can therefore easily review the electronic receipt on the Web browser in the open, without necessity of going home and using the personal computer or the like at home.
• Theportable terminal8 can access the merchandise-information providing server9, by using the electronic receipt downloaded from the electronic-receipt server6. Theportable terminal8 can then make thedisplay unit17 display the Web page about the merchandise, transmitted from the merchandise-information providing server9.
• Hence, the user can easily review the merchandise information in the Web page displayed on thedisplay unit17 of theportable terminal8. This easy access to the information about the merchandise bought is very useful for the user, and also to the shops because the merchandise information helps to promote the sales.

Therefore, they will not be explained here in detail.
• How the user accesses the merchandise information recorded on an electronic receipt by reviewing the electronic receipt on theportable terminal8 will be explained, with reference toFIG. 22.
• The user operates theinput unit18 provided on his or herportable terminal8, activating the electronic-receipt reviewing program P3.
• Since the electronic-receipt reviewing program P3 has been activated, the CPU11 of theportable terminal8 makes thedisplay unit17 display a list of all simplified settlement data items about the electronic receipts thus far received and recorded in the recording unit13 (Step S501). The CPU11 then prompts the user to select at least one of the simplified settlement data items.
• The CPU11 determines whether the user has selected any simplified settlement data item (Step S502). If the user has selected a simplified settlement data item, the CPU11 makes thedisplay unit17 displays the electronic receipt corresponding to the simplified settlement data selected (Step S503).
• The CPU11 then determines whether one of the items of merchandise recorded on the electronic receipt has been selected (Step S504). If any one of the items of merchandise has been selected, the CPU11 makes thedisplay unit17 display the menu about the merchandise selected (Step S505). If the input is not concerned with selection of merchandise, the operation returns to Step S502.
• After making thedisplay unit17 display the menu about the merchandise, the CPU11 determines whether the user has selected “purchase related products,” i.e., one of the menu items (Step S506). If “purchase related products” has been selected, the CPU11 extracts, from the data recorded on the electronic receipt, merchandise-purchase site ID and the date of purchasing the merchandise (Step S510). At this point, the place where the merchandise has been bought may be extracted, too.
• Thereafter, the CPU11 activates the merchandise-purchase-site reviewing program P11, accesses the merchandise-purchase site (i.e., merchandise purchase server90) via theInternet5 on the basis of the merchandise-purchase site ID, and transmits the date and time of purchasing the merchandise (Step S511). At the same time the date and time of purchasing the merchandise is transmitted, the data representing the site may be transmitted, too.
• If any item other than “review merchandise information” is selected in the menu, the operation returns to Step S504.
• The sequence of the major steps of the operation that themerchandise purchase server90 performs when the user operates theportable terminal8, thereby accessing the merchandise-purchase site, will be explained, with reference toFIG. 23.
• Themerchandise purchase server90 keeps activating the merchandise-information transmitting program P12 and keeps waiting for an access from the portable terminal8 (Step S601). In themerchandise purchase server90, theCPU61 receives the purchase-site reviewing data and the date and time of purchasing the merchandise from theportable terminal8 when theportable terminal8 makes a demand for reviewing the purchase information (Step S602).
• Next, theCPU61 extracts, from the merchandise-information managing area63aof therecording unit63, related merchandise recommended on the basis of the merchandise-purchase site ID contained in the purchase-site reviewing data and the date and time of purchasing the merchandise (Step S603). Assume the user of theportable terminal8 has bought wine and accesses themerchandise purchase server90 four days later. In this case, theCPU61 extracts “corkscrew,” “label-removing set,” and “wine X 750 ml,” as merchandise related to the wine.
• Thereafter, theCPU61 generates a purchase Web page for purchasing the related merchandise, on the basis of the data items extracted from the merchandise-information managing area63a(Step S604). TheCPU61 then transmits the Web page to theportable terminal8 that has accessed the merchandise-purchase site (Step S605).
• How theportable terminal8 operates when the user orders the related merchandise will be explained, with reference toFIG. 24.
• The CPU11 of theportable terminal8 receives the Web page for purchasing the related merchandise, sent from the merchandise purchase server90 (Step S701).
• The CPU11 then makes thedisplay unit17 display the Web page (Step S702).
• FIG. 27 shows another example of the information displayed by thedisplay unit17 of theportable terminal8 at this point. This example of information is displayed when the user accesses “wine 750 ml” four days after he or she has bought the same merchandise, i.e., “wine 750 ml.” The merchandise related to “wine 750 ml,” i.e., “corkscrew,” “label-removing set,” and “wine X 750 ml,” are displayed. The user can place an order for these related items of merchandise by operating theinput unit18.
• The user may operate theinput unit18, moving the cursor to any merchandise he or she would like to order and may push the OK button. Then, the CPU11 of theportable terminal8 determines that the user has selected the merchandise (Step S703). The CPU11 then transmits ordered-merchandise information designating the merchandise selected, to the merchandise purchase server90 (Step S704). If no merchandise is selected, the CPU11 transmits data representing the end of process to the merchandise purchase server90 (Step S705).
• The sequence of the major steps of the operation themerchandise purchase server90 performs when the user of theportable terminal8 orders merchandise will be explained, with reference toFIG. 25.
• Themerchandise purchase server90 keeps activating the merchandise-ordering program P13 at all times and keeps waiting for an access from the portable terminal8 (Step S801). Upon receiving an order for any merchandise from theportable terminal8, theCPU61 of themerchandise purchase server90 places order for the merchandise to the seller who sells the merchandise (Step S802). After placing the order, theCPU61 transmits a message to theportable terminal8, telling that the order has been accepted (Step S803). (The message may read, for example, “The order for the merchandise has been duly accepted.”)
• In the second embodiment, theportable terminal8 can access themerchandise purchase server90 on the basis of the data recorded on the electronic receipt downloaded from the electronic-receipt server6. Theportable terminal8 further can acquire, from themerchandise purchase server90, a Web page for ordering any merchandise and merchandise related thereto, and can cause thedisplay unit17 to display the Web page thus acquired. Using the Web page, the user can easily place an order for the merchandise displayed on thedisplay unit17.
• Thus, it is easy for the user to access the merchandise related to the merchandise purchased. This is very useful for the user, and also to the shops because the merchandise information helps to promote the sales.
