1-3: Management Server FIG. 3 is a block diagram showing the configuration of the management server 40. The management server 40 includes a processing device 410, a storage device 420, a display device 430, a communication device 440, an input device 450, and a clock device 470. Note that the term "apparatus" in this specification may be replaced with other terms such as circuit, device, or unit. Each element of the management server 40 is interconnected by a single bus or multiple buses for communicating information.

The processing device 410 is a processor that controls the entire management server 40, and is composed of, for example, a single chip or a plurality of chips. The processing device 410 includes, for example, a central processing unit that includes an interface with peripheral devices, an arithmetic unit, a register, and the like.

The transmitter 413 transmits the management information DI to the store device 10. More specifically, the transmitter 413 identifies the store device 10_y corresponding to the register ID [30_x] from among the plurality of store devices 10 based on the first management table TBL1. y is an integer from 1 to N2. The transmitting unit 413 transmits the management information DI to the store device 10_y using the specified IP address of the store device 10_y. The first management table TBL1 is an example of information indicating a correspondence relationship between identification information for identifying each of a plurality of two-dimensional code display devices and identification information for identifying each of a plurality of payment terminal devices. The store device 10_y is an example of a first information processing device.

The processing device 110 functions as the second acquisition section 111, the display control section 112, and the reception section 113 by reading out and executing the control program PR1 from the storage device 120. Note that the control program PR1 may be transmitted from another device such as the management server 40 via a network.

The second acquisition unit 111 acquires management information DI from the management server 40.

The reception unit 113 receives operations on the store device 10. A user may operate the store device 10, or a store employee may operate the store device 10.

Based on the management information DI, the display control unit 112 displays on the display device 130 an image for allowing the user to select a two-dimensional code corresponding to the payment service used for payment of the payment amount from among the plurality of two-dimensional codes. let Hereinafter, two types of modes of images displayed by the display control unit 112 on the display device 130 will be described.

1-4-1: First Display Mode In the first display mode, the display control unit 112 causes the display device 130 to display a plurality of icons A based on the icon information a and a payment amount based on the management information DI. When the reception unit 113 receives an operation in which one icon A is selected from among the plurality of icons A, the display control unit 112 displays a QR code C corresponding to the selected icon A based on the management information DI. is displayed on the display device 130. The person who selects icon A may be the user or a store employee who has received instructions from the user.

FIG. 7 is a flowchart showing the operation of the processing device 110 according to the first display mode. FIG. 8 is an explanatory diagram showing the transition of images displayed on the display device 130 in the first display mode. In step S10 shown in FIG. 7, the processing device 110 places the payment amount in the area W, and places three icons A1, A2, and A3 in the area V based on the icon information a1, a2, and a3. image information indicating the first image is generated. The processing device 110 causes the display device 130 to display the first image by supplying the generated image information to the display device 130.

In step S11 shown in FIG. 7, the processing device 110 determines whether a tap operation for selecting one of the icons A1, A2, and A3 has been received, and repeats the process of step S11 until the determination result becomes affirmative. If the process in step S11 is affirmative, in step S12, the processing device 110 places the payment amount in area W, places the QR code C corresponding to icon A that has received the tap operation in area X, and places icon A in step S12. is placed in area Y, and image information indicating a second image in which five indicators are placed in area Z is generated. The processing device 110 causes the display device 130 to display the second image by supplying the generated image information to the display device 130.
For example, the first image is displayed on the store device 10 on the left side of FIG. Here, when the user's tap operation on the icon A1 of the first image is received, the processing device 110 generates an image showing an image including the icon A1 and the QR code C1 corresponding to the icon A1, as an example of the second image. Generate information. In the store device 10 shown on the right side of FIG. 8, the payment amount is placed in the area W, the QR code C1 is placed in the area X, the icon A1 is placed in the area Y, and five indicators are placed in the area Z. The image is displayed. In the example of FIG. 8, four indicators are lit. The user recognizes the approximate time until the display of the second image is switched, based on the number of lit indicators.

Next, the processing device 110 determines whether a predetermined time has elapsed since the start of displaying the second image (step S13), and repeats the process of step S13 until the determination result becomes affirmative. The predetermined time is, for example, 30 seconds. In this case, the five indicators go out every six seconds. If the determination result in step S13 is affirmative, the processing device 110 returns the process to step S20.

In this way, by tapping the icon A corresponding to the payment service that the user wishes to use, the QR code C corresponding to the icon A is displayed on the display device 130, and the payment service that the user wishes to use is displayed on the display device 130. The user device 20 can be made to read the QR code corresponding to the QR code. Therefore, the space around the POS register 30 can be effectively utilized. In addition, even if the QR code is tampered with by pasting a sticker on the store device 10, the QR code is pasted in the area where the icon A should originally be displayed, so fraud can be easily recognized. Furthermore, upon reading the QR code C, the user device 20 uses the access information represented by the QR code C to transmit a payment request to the payment server. Therefore, the user does not have to input the payment amount, and the user's input effort can be reduced. Furthermore, since the user does not have to input the payment amount, the payment system 1 can relieve the user from worrying about inputting the wrong payment amount.

1-4-2: Second Display Mode In the second display mode, the display control unit 112 displays a plurality of QR codes C in order on the display device 130.

FIG. 9 is a flowchart showing the operation of the processing device 110 according to the second display mode. FIG. 10 is an explanatory diagram showing the transition of images displayed on the display device 130 in the second display mode. In step S20 shown in FIG. 9, the processing device 110 generates image information indicating the third image and supplies the generated image information to the display device 130, thereby displaying the third image on the display device 130. The display device 130 that is displaying the third image is shown on the left side of FIG. The processing device 110 places the payment amount in the area W based on the amount information PI, places the QR code C1 in the area X based on the QR code information c1, and places the icon A1 in the area Y based on the icon information a1. Furthermore, image information indicating a third image in which five indicators are arranged in area Z is generated.

Furthermore, the processing device 110 turns off the five indicators displayed in the area Z over time. Next, the processing device 110 advances the process to step S21 and determines whether a predetermined time has elapsed since the start of displaying the first image.

If the determination result is negative, the processing device 110 repeats the determination in step S21. If the determination result in step S21 is affirmative, the processing device 110 generates image information indicating the second image and supplies the generated image information to the display device 130, thereby displaying the fourth image on the display device 130. (Step S22). The display device 130 that is displaying the fourth image is shown in the center of FIG. The processing device 110 places the payment amount in the area W based on the amount information PI, places the QR code C2 in the area X based on the QR code information c2, places the icon A2 in the area Y, and further places the payment amount in the area Z Image information indicating a fourth image in which five indicators are arranged is generated. Similarly to the third image, the processing device 110 turns off the five indicators displayed in the area Z in the fourth image as time passes.

Thereafter, the processing device 110 determines whether a predetermined time has elapsed since the start of displaying the fourth image (step S23), and repeats the process of step S23 until the determination result becomes affirmative. If the determination result in step S23 is affirmative, the processing device 110 causes the display device 130 to display the fifth image by generating image information indicating the fifth image and supplying the generated image information to the display device 130. (Step S24). The display device 130 that is displaying the fifth image is shown on the right side of FIG. The processing device 110 places the payment amount in the area W based on the amount information PI, places the QR code C3 in the area X based on the QR code information c3, places the icon A3 in the area Y, and further places the payment amount in the area Z Image information indicating a fifth image in which five indicators are arranged is generated.

Next, the processing device 110 determines whether a predetermined time has elapsed since the start of displaying the fifth image (step S25), and repeats the process of step S25 until the determination result becomes affirmative. If the determination result in step S25 is affirmative, the processing device 110 returns the process to step S20. The processing from step S20 to step S25 is realized by the display control unit 112 described above.

In this way, the user can use the QR codes C1, C2, and C3, which correspond one-to-one to the first payment service, the second payment service, and the third payment service, by sequentially displaying them on the display device 130. The user device 20 can be made to read the QR code corresponding to the payment service. Further, when the user device 20 reads the QR code C1, C2, or C3, it uses the access information represented by the QR code C to transmit a payment request to the payment server. Therefore, the user does not have to input the payment amount, and the user's input effort can be reduced. Furthermore, since the user does not have to input the payment amount, the payment system 1 can relieve the user from worrying about inputting the wrong payment amount.

The payment request generation unit 212 causes the payment server corresponding to the QR code C imaged using the communication device 240 to transmit a payment request including payment information.

1-6: Operation of payment system 1 FIG. 12 is a sequence chart showing an example of the operation of payment system 1. In the example shown in FIG. 12, the case where the display mode of the display control unit 112 is the first display mode and the user selects to use the first payment service will be described as an example.

The POS register 30_x reads the barcode of the product and calculates the payment amount to be paid by the user (step Sa1). The POS cash register 30_x transmits the amount information PI indicating the payment amount and the cash register ID [30_x] to the management server 40 (step Sa2).

The management server 40 acquires the amount information PI and the cash register ID [30_x] from the POS cash register 30_x (step Sb1). The management server 40 generates management information DI based on the amount information PI (step Sb2). The management server 40 transmits the management information DI to the store device 10_y corresponding to the cash register ID [30_x] (step Sb3).

The store device 10_y acquires management information DI from the management server 40 (step Sc1). Next, the store device 10_y displays the plurality of icons A and the payment amount based on the management information DI (step Sc2). The store device 10_y accepts a tap operation to select one of the plurality of icons A (step Sc3). When the store device 10_y receives the tap operation, the store device 10_y causes the display device 130 to display the QR code C corresponding to the icon A selected by the tap operation (step Sc4).

On the other hand, when the user device 20 receives an operation to start a payment application software (hereinafter simply referred to as a "payment application") by a user who intends to use a payment service, the processing device 210 executes one of the control programs PR3. The payment application program is read out from the storage device 220 to start the payment application (step Sd1). After the completion of starting the payment application, the processing device 210 acquires imaging information indicating the QR code C, which is obtained by the imaging device 260 imaging the QR code C displayed on the display device 130 (step Sd2). After the processing in step Sd2, the processing device 210 functions as the decoding section 211, and the decoding section 211 executes a decoding process to decode the imaging information (step Sd3). Through the decoding process, the URL of the payment server corresponding to the payment service used by the user is obtained. In the example of FIG. 12, since the user uses the first payment service, the URL of the first payment server 50 is specified. The processing device 210 functions as a payment request generation unit 212, and the payment request generation unit 212 generates a payment request including the payment amount and a user ID that identifies the user, and uses the URL of the first payment server 50 to complete the payment. The request is sent to the first payment server 50 (step Sd4).

The first payment server 50 that has received the payment request executes payment processing (step Se1). In the payment process, the first payment server 50 subtracts the payment amount from the balance of the user's account linked to the user ID. Thereafter, the first payment server 50 transmits a payment response indicating that the payment has been completed to the user device 20 (step Se2). In addition, the first payment server 50 transmits a payment completion notification indicating that the payment has been completed to the POS register 30_x (step Se3).

As described above, according to the present embodiment, the management server 40 includes the POS register 30 (an example of a payment terminal device) that calculates the payment amount paid by the user, and the store device 10 that displays a two-dimensional code representing the payment amount. (an example of an information processing device). The management server 40 corresponds one-to-one with a first acquisition unit 411 that acquires amount information PI indicating the payment amount from the POS register 30 and a plurality of payment services, and has a plurality of QR codes C (two-dimensional It includes a generation unit 412 that generates management information DI related to the code (an example of a code) based on amount information PI, and a transmission unit 413 that transmits the management information DI to the store device 10. According to the management server 40, since the management information DI regarding the QR code C representing the payment amount is transmitted to the store device 10, the user does not have to input the payment amount, and the user's input effort can be reduced.

Further, the payment system 1 includes a plurality of POS registers 30 and a plurality of store devices 10, and the first acquisition unit 411 further includes a POS register 30_x (an example of a first information processing device) among the plurality of POS registers 30. ) for identifying the register ID [30_x] (an example of the first identification information) from the POS register 30_x, and the transmitter 413 acquires the register ID [30_x] (an example of the first identification information) for identifying the first management table TBL1 (identifying information for identifying each of the plurality of information processing devices Based on an example of information indicating a correspondence relationship with identification information that identifies each of a plurality of payment terminal devices, the store device 10_y indicated by the store ID corresponding to the cash register ID [30_x] is selected from among the plurality of store devices 10. (an example of a first information processing device) and transmits management information DI to the specified store device 10_y. According to the management server 40, the management information DI can be sent to the store device 10 corresponding to the POS register 30 that sent the cashier ID, so the payment system 1 includes a plurality of POS registers 30 and a plurality of store devices 10. This embodiment can be applied even in cases where

The store device 10 also includes a second acquisition unit 111 that has one-to-one correspondence with a plurality of payment services and acquires management information DI regarding a plurality of QR codes C representing the payment amount paid by the user; It also includes a display control unit 112 that causes the display device 130 to display an image that allows the user to select the QR code C corresponding to the payment service used for payment of the payment amount from among the plurality of QR codes C. Since the QR code C based on the management information DI represents the payment amount, the user device 20 can obtain the payment amount by reading the QR code C. Therefore, the user does not have to input the payment amount, and the user's input effort can be reduced.

Further, in the first display mode, the display control unit 112 further includes a reception unit 113 that receives an operation, and the management information DI further includes an icon indicating a plurality of icons A in one-to-one correspondence with a plurality of QR codes C. The display control unit 112 further causes the display device 130 to display a plurality of icons A based on the icon information a and a payment amount based on the management information DI, and displays a certain one of the plurality of icons A. When the reception unit 113 receives an operation in which one icon A (an example of one icon) is selected, the QR code C corresponding to the selected icon A is displayed on the display device 130 based on the management information DI. . In the second display mode, for example, if the payment service that the user wants to use is a third payment service, the user must wait until the third image is displayed on the display device 130. On the other hand, according to the first display mode, the user only has to select the icon A corresponding to the payment service he or she wants to use, so he or she waits until an image with the QR code C corresponding to the payment service he or she wants to use is displayed. User convenience can be improved.

Furthermore, in the second display mode, the display control unit 112 causes the display device 130 to sequentially display a plurality of QR codes C based on the management information DI. The user only has to use the user device 20 to read the QR code C of the payment service to be used among the QR codes C sequentially displayed on the display device 130. Therefore, even if the display device 130 is small, multiple Can support payment services.

Furthermore, each of the plurality of QR codes C represents access information for accessing a payment server that provides a one-to-one payment service. The user device 20 can acquire access information by decoding the captured information obtained by capturing an image of the QR code C.

2. Modifications The present disclosure is not limited to the embodiments illustrated above. Specific modes of modification are illustrated below. Two or more aspects arbitrarily selected from the examples below may be combined.

2-1: First Modification In the second display mode of the display control unit 112, the third image displays the icon A1 corresponding to the QR code information c1, and the icon A2 and the icon A3 are not displayed. However, icon A2 and icon A3 may be displayed. However, in order to indicate that the currently displayed QR code C corresponds to the first payment service, it is preferable to highlight the icon A1 corresponding to the QR code C1.

FIG. 13 is a flowchart showing the operation of the processing device 110 according to the first modification. FIG. 14 is an explanatory diagram showing the transition of images displayed on the display device 130 in the first modification. In step S30 shown in FIG. 13, the processing device 110 generates image information indicating the sixth image and supplies the generated image information to the display device 130, thereby displaying the sixth image on the display device 130. The display device 130 that is displaying the sixth image is shown on the left side of FIG. 13. The processing device 110 places the payment amount in the area W based on the amount information PI, places the QR code C1 in the area X based on the QR code information c1, and places the QR code C1 in the area Y based on the icon information a1, a2, and a3. Image information indicating a sixth image in which icons A1, A2, and A3 are placed in area Z, and five indicators are placed in area Z is generated. Further, the icon A1 corresponding to the QR code C1 being displayed is highlighted. In the example shown in FIG. 14, the outer frame of icon A is made thicker. The highlighted display allows the user to recognize that the displayed QR code C1 is the QR code C for the first payment service.

Furthermore, similarly to the second display mode, the processing device 110 turns off the five indicators displayed in the area Z over time. Next, the processing device 110 advances the process to step S31 and determines whether a predetermined time has elapsed since the start of displaying the first image.

If the determination result is negative, the processing device 110 repeats the determination in step S31. If the determination result in step S31 is affirmative, the processing device 110 causes the display device 130 to display the seventh image by generating image information indicating the seventh image and supplying the generated image information to the display device 130. (Step S32). The display device 130 that is displaying the seventh image is shown in the center of FIG. The processing device 110 places the payment amount in the area W based on the amount information PI, places the QR code C2 in the area X based on the QR code information c2, and places icons A1, A2, and A3 in the area Y. Furthermore, image information indicating a seventh image in which five indicators are arranged in area Z is generated. Further, the icon A2 corresponding to the QR code C2 being displayed is highlighted. Similarly to the sixth image, the processing device 110 turns off the five indicators displayed in the area Z in the seventh image as time passes.

Thereafter, the processing device 110 determines whether a predetermined time has elapsed since the start of displaying the seventh image (step S33), and repeats the process of step S33 until the determination result becomes affirmative. If the determination result in step S33 is affirmative, the processing device 110 causes the display device 130 to display the eighth image by generating image information indicating the eighth image and supplying the generated image information to the display device 130. (Step S34). The display device 130 is shown on the right side of FIG. 14 while displaying the eighth image. The processing device 110 places the payment amount in the area W based on the amount information PI, places the QR code C3 in the area X based on the QR code information c3, and places icons A1, A2, and A3 in the area Y. Furthermore, image information indicating an eighth image in which five indicators are arranged in area Z is generated. Furthermore, the icon A3 corresponding to the QR code C3 being displayed is highlighted.

Next, the processing device 110 determines whether a predetermined time has elapsed since the start of displaying the eighth image (step S35), and repeats the process of step S35 until the determination result becomes affirmative. If the determination result in step S35 is affirmative, the processing device 110 returns the process to step S30. The processing from step S30 to step S35 is realized by the display control unit 112 described above.

2-2: Second Modified Example In each of the above aspects, the QR code information c included in the management information DI is a QR code C that represents the payment amount and access information for accessing the payment server that provides the payment service. The image information is not limited to this. For example, the QR code information c may include access information instead of the QR code C. Note that since the amount information PI is included in the management information DI, the QR code information c does not have to include the payment amount. The store device 10 that has acquired the management information DI generates image information of the QR code C based on the amount information PI included in the management information DI and the access information included in the management information DI.

2-3: Third Modification In each of the above-mentioned aspects, the management information DI does not need to have the amount information PI indicating the payment amount. However, the image information of the QR code C, which is the QR code information c included in the management information DI, indicates the QR code C representing the payment amount and access information. If the management information DI does not include the amount information PI, the display control unit 112 does not need to display the payment amount indicated by the amount information PI on the display device 130. Alternatively, even if the management information DI does not have amount information PI, the display control unit 112 obtains the payment amount by decoding the QR code C included in the management information DI, and displays the obtained payment amount. The amount may also be displayed.

2-4: Fourth Modification In each of the above embodiments, the management information DI includes the icon information a, but the icon information a may not be included. For example, as an initial setting when a store subscribes to a payment service, the management server 40 transmits icon information a to the store device 10. The store device 10 stores the received icon information a in the storage device 120. To explain using FIG. 12, in step Sc2, the store device 10_y displays a plurality of icons A based on the icon information a stored in the storage device 120, and displays the payment amount based on the management information DI.
In the first embodiment, icon information a is transmitted to the store device 10 every time the amount information PI is notified from the POS register 30. On the other hand, in the fourth modification, the icon information a only needs to be transmitted to the store device 10 once. Therefore, according to the fourth modification, the amount of communication between the management server 40 and the store device 10 can be suppressed compared to the first embodiment.

2-5: Fifth Modification In each of the above embodiments, the store device 10 may change the area in which the QR code C is displayed.

2-6: Sixth variation In each of the above aspects, QR code C is a static QR code that is the same for multiple payments when the payment amount and access information are the same, but the payment amount and access information are the same. Dynamic QR codes may have the same information or different dynamic QR codes. For example, the generation unit 412 encodes information that combines the payment amount indicated by the amount information PI, the URL of the payment server, and a time character string indicating the current time, and converts the image information of the obtained dynamic QR code C into a QR code. It is generated as code information c. The decoding unit 211 acquires the payment amount, the URL of the payment server, and the time character string from the dynamic QR code indicated by the QR code information c. For example, the payment request generation unit 212 generates a payment request if the value obtained by subtracting the time indicated by the time character string from the current time is within a predetermined value, and if it exceeds the predetermined value, the payment request generation unit 212 generates a payment request. Disable the dynamic QR code and do not generate payment requests.
According to the sixth modification, a dynamic QR code that is changed at any time is used, so security can be strengthened.

2-7: Seventh Modification In each of the above aspects, the payment system 1 includes a plurality of store devices 10 and a plurality of POS registers 30, but the payment system 1 includes one store device 10 and one or more POS registers 30. POS register 30 may also be provided. A payment system 1a according to a seventh modification, which includes one store device 10 and one or more POS registers 30, will be described using FIG. 15.

FIG. 15 is a diagram showing the functions of the payment system 1a according to the seventh modification. The payment system 1a includes user devices 20_1, ..., user device 20_N1, store device 10a, POS register 30a_1, ..., POS register 30a_N3, management server 40a, first payment server 50, second payment server 60, and third payment It has a server 70. N1 is an integer of 1 or more. N3 is an integer of 1 or more.

The storage device 420 according to the seventh modification does not need to store the first management table TBL1. However, the storage device 420 according to the seventh modification stores the IP address of the store device 10a. The second management table TBL2 according to the seventh modification stores a payment service ID, a payment server URL, and icon information a in association with each other for payment services that can be used by the store device 10a. The processing device 410 according to the seventh modification reads out and executes the control program PR2 according to the seventh modification from the storage device 420 according to the seventh modification, thereby controlling the first acquisition unit 411a, the generation unit 412, and , functions as a transmitter 413a.

The first acquisition unit 411a acquires amount information PI from the POS register 30a_x. The first acquisition unit 411a does not need to acquire the register ID of the POS register 30a_x. The transmitter 413a transmits the management information DI to the store device 10a.

According to the seventh modification, the user does not have to input the payment amount for the payment system 1a including one store device 10a and one or more POS registers 30a, simplifying the operation of the user device 20. Can be done.

2-8: Eighth Modification In each of the above-mentioned aspects, payment services available to the user need to be registered in advance. Therefore, the plurality of payment services displayed on the store device 10 may include payment services for which the user is not registered. Therefore, when the user reads a QR code related to an unregistered payment service, the processing device 110 of the user device 20 may display the payment services available to the user on the display device 230. Note that a message urging the user to subscribe to an unregistered payment service may be displayed on the display device 230.
