In the example of FIG. 10, the display unit 22 and the input unit 23 are an integrated touch panel, and an input field for the total amount to be settled is displayed on the upper half of the screen, and a numeric keypad for numerical input is displayed on the lower half of the screen. Is displayed. Thereafter, the store terminal 20 is operated by a store clerk, reads and recognizes the barcode displayed on the user terminal 10, and acquires a barcode numerical value as barcode information (step S201).

  The shop terminal 20 transmits the cookie including the business ID and the barcode numerical value to the barcode server 100 via the proxy server 400 (step S202) (step S203). The reference unit 132 of the barcode server 100 refers to the barcode management information storage unit 122 (step S204), and acquires the background URL, user ID, and usage point number corresponding to the received barcode numerical value (step S205). . The reference unit 132 transmits the acquired background URL, user ID, and usage point to the shop terminal 20 via the proxy server 400 (step S206) (step S207).

  The settlement processing unit 26 of the store terminal 20 acquires a confirmation image based on the received background image URL and displays it on the display unit 22. Further, the settlement processing unit 26 displays a settlement confirmation screen on the display unit 22 based on the user ID of the user terminal 10, the number of used points, and price information. Here, FIG. 11 shows an example of a payment confirmation screen of the store terminal 20 according to the embodiment. In the settlement confirmation screen shown in FIG. 11, for example, the accounting amount corresponding to the price information is 1000 yen, the number of used points is 50 points, and the payment amount is 950 yen. Here, when the confirmation button B22 is pressed by the user who applied for settlement (the user of the user terminal 10), confirmation information indicating that confirmation has been performed by the user is acquired (step S208). Further, when the reverse button B23 is pressed, the screen is turned upside down. Note that a button B21 for switching the confirmation image may be provided on the payment confirmation screen. Further, an ON / OFF button for a confirmation image may be provided on the payment confirmation screen, and an instruction may be sent to the barcode server 100 so that the confirmation image is distributed to the user terminal 10 and the store terminal 20 for the first time at the time of payment confirmation.

  When the settlement processing unit 26 of the store terminal 20 obtains the confirmation information by pressing the confirm button B22, the cookie, the barcode numerical value, the price, the store ID, and the M-key are passed through the proxy server 400 (step S209). It transmits to the settlement server 200 (step S210). The gateway unit 231 of the settlement server 200 outputs the received barcode numerical value to the reference unit 132 of the barcode server 100 (step S211). The reference unit 132 of the barcode server 100 refers to the barcode management information storage unit 122 based on the barcode numerical value (Step S212), and acquires the user ID, the number of used points, and the application Ver corresponding to the barcode numerical value. (Step S213). The reference unit 132 outputs the acquired user ID, the number of used points and the application Ver, and the barcode issue time or expiration date to the gateway unit 231 of the payment server 200 (step S214).

  The gateway unit 231 of the settlement server 200 receives the user ID, usage point, application Ver, and barcode issuance time or expiration date from the reference unit 132 of the barcode server 100, and the information reference unit 232 receives the user ID. (Step S215). The information reference unit 232 transmits the user ID to the wallet server 300 (step S216), and acquires the user's mail address, wallet information, and point balance corresponding to the user ID (step S217). Thereafter, the information reference unit 232 outputs the acquired mail address, wallet information, and point balance to the gateway unit 231 (step S218).

  The gateway unit 231 receives the mail address, wallet information, and point balance related to the user ID from the information reference unit 232, and then sends the user ID, usage points, store ID, M-key, price, wallet to the settlement unit 233. Information and a mail address are output (step S219). The settlement unit 233 receives the user ID, usage point, store ID, M-key, price, wallet information, and email address from the gateway unit 231 and performs settlement based on these. The settlement unit 233 outputs settlement completion information to the gateway unit 231 (step S220).

  The gateway unit 231 of the payment server 200 transmits the input payment completion information to the store terminal 20 via the proxy server 400 (step S221) (step S222). Here, FIG. 12 shows an example of a payment completion screen of the store terminal 20 according to the embodiment. The payment details are displayed on the payment completion screen. When the completion button B24 is pressed, a receipt screen is displayed on the user terminal 10. FIG. 13 shows an example of a receipt screen of the user terminal 10 according to the embodiment.

  Further, the gateway unit 231 of the settlement server 200 transmits the barcode numerical value to the deletion unit 133 of the barcode server 100 (step S223). The deletion unit 133 deletes all information of the management ID related to the barcode numerical value in the barcode management information storage unit 122 (step S224). When the deletion is completed (step S225), the deletion unit 133 transmits the deletion result to the gateway unit 231 of the settlement server 200 (step S226).

[10. effect]
As described above, the barcode server 100 including the function of the confirmation image distribution server selects image data from the image storage unit 121 that stores a plurality of image data, and stores the image data in the first terminal device (user terminal 10). While transmitting, the same image data is transmitted to the 2nd terminal device (shop terminal 20) which performs the process collaborated with the 1st terminal device. Thereby, in the barcode server 100 used for the confirmation image distribution system 1, it is possible to prevent the product and the user who makes the payment from being mixed.

  The barcode server 100 receives first identification information for identifying the first terminal device from the first terminal device, transmits the barcode data together with the image data to the first terminal device, 2nd identification information which identifies 2 terminal devices, and the barcode information which read the barcode displayed on the 1st terminal device with the 2nd terminal device are received from the 2nd terminal device, barcode information Based on the second identification information, the same image data is transmitted to the second terminal device. Thereby, the barcode server 100 can transmit the same image data as the first terminal device to the second terminal device by reading the barcode displayed on the first terminal device with the second terminal device. In addition, by confirming the matching of the images, it is possible to prevent a difference between the product and the user who makes the payment.

  Further, the barcode server 100 receives first identification information for identifying the first terminal device from the first terminal device, and transmits the barcode data to the first terminal device before transmitting the image data. The second identification information for identifying the second terminal device and the barcode information obtained by reading the barcode displayed on the first terminal device with the second terminal device are received from the second terminal device, Based on the barcode information and the second identification information, the same image data is transmitted to the first terminal device and the second terminal device. As a result, if the barcode is not read, the image is not displayed on either terminal, so that it is possible to prevent unauthorized use on the store side, which has conventionally not been taken much measures. For this reason, it is possible to easily realize a cashless transaction by wallet settlement even in a store such as a flea market that does not have a fixed store.

  As an example of fraudulent use, it may be possible to make a payment by forging a screen with payment contents lower than the actual payment amount. On the other hand, when the payment information screen is forged by transmitting image data to the user terminal 10 and the store terminal 20 after reading the barcode information at the store terminal 20, the images are the same. Therefore, forgery can be easily prevented.

  As another example, in a configuration in which the user ID is converted into a barcode as it is, the barcode read by the store side may be illegally used at a later date. On the other hand, since the image data is transmitted to the user terminal 10 and the store terminal 20 after reading the barcode information, the image data is also transmitted to the user terminal 10 when used illegally at a later date. The user of the user terminal 10 can easily find out that the user has been illegally used and can take immediate countermeasures, thus preventing damage.

  Further, the barcode server 100 transmits information for displaying an image display button to the first terminal device and the second terminal device, and the barcode information, the second identification information, and the first terminal device. Alternatively, image data is transmitted to the first terminal device and the second terminal device based on the image display information of the image display button transmitted from the second terminal device. Thereby, an image can be displayed on a 1st terminal device and a 2nd terminal device at arbitrary timings, when a user presses an image display button.

  As image data, image data generated from one or more of colors, patterns, figures, and characters is used. Here, an example of an image is shown in FIG. 14A shows an example of a color-only image, FIG. 14B shows an example of a pattern-only image, FIG. 14C shows an example of a graphic-only image, and FIG. (D) shows an example of a character-only image. As the image used for the image data, for example, the image data may be generated by freely combining the images shown in FIGS. As a result, even a user who does not check payment details can easily determine that the images are different.

  Further, as the image data, data including an advertisement of a store or the like that is a user of the second terminal device is used. Here, FIG. 15 shows an example of a barcode display screen including an advertisement. The bar code display screen of FIG. 15 represents a state in which a confirmation image A11 provided with an advertisement column A12 is displayed, for example. Thereby, for example, it is possible to exert an advertising effect such as disseminating the store logo mark in the advertisement column A12. The advertisement is not limited to being displayed in the advertisement column A12, but may be displayed over the entire confirmation image A11. In the example of FIG. 15, the advertisement is displayed on the barcode display screen of the user terminal 10, but the present invention is not limited to this, and the advertisement may be displayed on the settlement confirmation screen of the store terminal 20. Furthermore, the advertisement is not limited to the advertisement of the store that is the user of the second terminal device, and may be an advertisement of a related store or the like according to the customer segment, the store genre, or the like.

[11. Others]
As described above, some of the embodiments of the present application have been described in detail with reference to the drawings. However, these are merely examples, and various modifications, including the aspects described in the disclosure section of the invention, based on the knowledge of those skilled in the art, It is possible to implement the present invention in other forms with improvements.

  For example, in the above embodiment, the first terminal device is described as the user terminal 10 and the second terminal device is described as the store terminal 20, but the present invention is not limited to this. For example, when it is desired to settle a split account between individual users, the settlement amount is input to one user terminal 10 and the other user terminal 10 requests the barcode server 100 to issue a barcode. The other user terminal 10 displays the barcode and confirmation image received from the barcode server 100. One user terminal 10 reads the barcode displayed on the other user terminal 10 with an imaging unit (not shown). Subsequently, the other user terminal 10 transmits the barcode information and the user ID of the other user terminal 10 to the barcode server 100. The barcode server 100 refers to the barcode management information storage unit 122 and transmits the same confirmation image as that of the one user terminal 10 to the other user terminal 10. The other user terminal 10 displays the received confirmation image. The user can determine that payment may be performed by looking at the confirmation images of both user terminals 10.

  For example, in the above embodiment, the barcode issued by the barcode server 100 is generated from the one-time password, but the present invention is not limited to this. For example, the user ID may be used as it is as a barcode, and in this case, the security of settlement can be further enhanced by being able to visually confirm the confirmation image.

  Moreover, in said embodiment, although the confirmation image was displayed on the user terminal 10 simultaneously with the barcode, it is not limited to this. For example, confirmation image data may be transmitted to the user terminal 10 and the store terminal 20 in response to a request from the user terminal 10 or the store terminal 20. The user terminal 10 requests the barcode server 100 to issue a barcode. The barcode server 100 transmits only barcode data to the user terminal 10. The store terminal 20 reads the barcode displayed on the user terminal 10. The store terminal 20 transmits the barcode information and the store ID to the barcode server 100. The barcode server 100 refers to the barcode management information storage unit 122 and transmits information for displaying the confirmation image display button to the user terminal 10 and the store terminal 20. When the user presses the confirmation image display button at the user terminal 10 or the store terminal 20, the user terminal 10 or the store terminal 20 requests a confirmation image from the barcode server 100. Upon receiving the request, the barcode server 100 selects the image data and transmits the same confirmation image data to the user terminal 10 and the store terminal 20 (sends a background URL). As a result, since the confirmation image is displayed on both terminals while the user is viewing both the user terminal 10 and the store terminal 20, it is possible to prevent the user from making a clear payment with the product. can do.

  In addition, the confirmation image may be requested to be redisplayed from the user terminal 10 or the store terminal 20. For example, as in the above embodiment, a confirmation image is displayed on the user terminal 10 and the store terminal 20. At this time, for example, a redisplay button is displayed on the store terminal 20. When the user presses the redisplay button, the store terminal 20 transmits redisplay information to the barcode server 100. When the bar code server 100 receives the redisplay information, the bar code server 100 acquires an unused image from the image storage unit 121 and transmits it to the user terminal 10 and the store terminal 20 as new confirmation image data. As a result, the confirmation image is redisplayed on both terminals while the user is viewing both the user terminal 10 and the store terminal 20, so that the user and the user who makes the payment with the product more clearly. Can be prevented.

  Moreover, in said embodiment, although the receipt screen was displayed on the user terminal 10 about the payment content, it is not limited to this. For example, the payment server may send the payment contents to the user by e-mail to the address registered in the wallet information.

  In the above embodiment, the barcode is used as the relationship information, but the present invention is not limited to this. For example, a numerical value corresponding to a barcode numerical value may be transmitted from the user terminal 10 to the store terminal 20 by infrared communication, or WiFi (Wireless Fidelity) or the like may be used. Further, the data acquired by each terminal may be transmitted to the barcode server 100 without directly transmitting and receiving data between the user terminal 10 and the store terminal 20. For example, the user terminal 10 and the store terminal 20 transmit position information and vibration information to the barcode server 100. The barcode server 100 transmits confirmation image data together with the respective user IDs to the user terminal 10 and the store terminal 20 that have transmitted similar vibration information within a certain range based on the position information. The user terminal 10 and the store terminal 20 display confirmation image data. If the confirmation images displayed on both sides are the same, the user can confirm that the other party's user ID sent together with the confirmation image data is correct.
