The payment processing unit 12 performs CPM code payment by cooperating with the code payment application on the terminal side and the code payment application on the store side.

The payment history recording unit 13 records a history of code payments performed by the payment processing unit 12 for each user (user identification information (user ID)).

The privilege provision processing unit 14 performs privilege provision processing. In the present embodiment, a privilege using NFT is granted to the user who used the code payment by the privilege granting process.

Next, an information processing method according to this embodiment will be described with reference to FIG. FIG. 3 is a sequence diagram showing an example of the procedure of the information processing method according to this embodiment. When a user purchases a product at a store, the user pays for the product by code payment.

(Step S101) A user purchases a product at a store. The user activates the code payment application on the user terminal 2 and performs an operation to display the payment code on the user terminal 2 when paying at the store.

(Step S102) When the user terminal 2 accepts the operation for displaying the payment code, the user terminal 2 transmits the user ID and the payment code issuance request (code issuance request) for the user to pay at the store to the information processing device. Send to 1. The user ID that the user terminal 2 transmits to the information processing device 1 is a user ID registered in the code payment application in the user terminal 2 in advance.

The payment processing unit 12 in the information processing device 1 receives from the user terminal 2 a user ID and a payment code issuance request (code issuance request) for the user to make a payment at a store.

(Step S103) Upon receiving the user ID and the code issuance request from the user terminal 2, the payment processing unit 12 generates code information for generating a payment code. The payment code is generated as a one-time (disposable) code. Therefore, code information is also one-time information.

(Step S104) The payment processing unit 12 causes the storage unit 11 to store the generated code information in association with the user ID received from the user terminal 2 that issued the code issue request.

(Step S105) The payment processing unit 12 transmits the generated code information to the user terminal 2 that has issued the code issue request.

(Step S106) Upon receiving the code information from the information processing device 1, the user terminal 2 generates a settlement code by a predetermined code generation method using a code settlement application based on the received code information. The user terminal 2 displays the generated settlement code on the display screen of its own user terminal 2 .

(Step S107) The user presents the payment code displayed on the display screen of the user terminal 2 when paying for the product at the accounting place of the store. The store terminal 3 reads the settlement code displayed on the display screen of the user terminal 2 by, for example, an operation by a store clerk.

(Step S108) Upon reading the payment code, the store terminal 3 generates payment information. The payment information is information including shop identification information (shop ID), payment amount, and accounting date and time. The store ID is registered in advance in the code payment application at the store terminal 3 . The settlement amount is the total amount of products purchased by the user. The accounting date and time is the current date and time in the shop terminal 3 . The payment information may include identification information (product ID) of the product purchased by the user.
Also, the store ID may be information including identification information of a business operator that operates the store and identification information unique to each store. For example, if there are X town store and Y station-front store as stores operated by P company, the store ID of X town store is common to both stores, "identification information of P company" and "unique to X town store". On the other hand, the store ID of Y station-front store includes "identification information of P business" common to both stores and "identification information specific to Y station-front store".
Also, the accounting date and time may be the date and time when the store terminal 3 transmits the payment information to the information processing device 1 .

(Step S<b>109 ) The store terminal 3 transmits the generated payment information and the code information indicated by the payment code read from the user terminal 2 to the information processing device 1 . The payment processing unit 12 in the information processing device 1 receives payment information and code information from the store terminal 3 .
The information processing device 1 may use the date and time when the payment information is received from the store terminal 3 as the accounting date and time.

(Step S<b>110 ) Upon receiving the payment information and the code information from the store terminal 3 , the payment processing unit 12 determines whether the received code information matches the code information stored in the storage unit 11 . If the received code information and the code information stored in the storage unit 11 match, the payment processing unit 12 makes a payment based on the user ID associated with the code information and the payment information received from the shop terminal 3. payment.

In the settlement performed by the settlement processing unit 12, the settlement processing unit 12 executes a process of withdrawing the settlement amount indicated by the settlement information from the account of the user identified by the user ID associated with the code information in the storage unit 11. The settlement processing unit 12 also executes processing for depositing the settlement amount into the account of the store specified by the store ID indicated by the settlement information. Here, the settlement processing unit 12 may deposit the amount obtained by deducting a predetermined fee from the settlement amount into the account of the store.

(Step S111) When the payment is completed, the payment processing unit 12 transmits a payment completion notice indicating that the payment for the product has been completed to each of the user terminal 2 and the shop terminal 3. FIG.

(Step S112) Upon receiving the payment completion notification from the information processing device 1, the user terminal 2 causes the display screen of the own user terminal 2 to display that the payment for the product has been completed. Thereby, the user recognizes that the payment for the product has been completed. Upon receiving the payment completion notification from the information processing device 1, the shop terminal 3 causes the display screen of the own shop terminal 3 to display that the payment for the product has been completed. Thereby, the store clerk recognizes that the payment for the product has been completed.

(Step S113) In the information processing device 1, when the payment processing unit 12 completes the payment, the payment history recording unit 13 records the history of the code payment performed by the payment processing unit 12 regarding the payment. The history of code settlement includes user ID, store ID, accounting date and time, and settlement amount. As a result, the number of purchases per store, the total amount of payments, and the like can be totaled for each user.
Note that the payment history recording unit 13 may record various types of user attribute information (for example, age, address, etc.) for the user corresponding to the user ID in the code payment history. The attribute information of each user is registered in the information processing apparatus 1 in association with the user ID, for example, at the time of user registration.

(Step S201) The privilege granting processing unit 14 in the information processing device 1 determines whether or not the information regarding the payment completed in step S110 (hereinafter referred to as target payment information) satisfies a predetermined privilege granting condition. . The privilege provision conditions include conditions regarding at least one of the store and the product. The privilege provision conditions are registered in advance in the privilege management table 11T.

The privilege granting processing unit 14 determines whether there is a privilege granting condition satisfied by the target payment information among the privilege granting conditions included in the privilege management table 11T. As a result of this determination, if there is a privilege giving condition that the target payment information satisfies in the privilege management table 11T, the privilege identification information (privilege ID) associated with the target payment information is specified, and the processing of the next step S202 is executed. . On the other hand, if there is no privilege giving condition that the target payment information satisfies in the privilege management table 11T, the procedure of FIG. 3 is terminated.

Now, with reference to FIG. 4, a privilege provision condition according to the present embodiment will be described. FIG. 4 is a diagram showing a configuration example of a privilege management table according to this embodiment. In the example of FIG. 4, for each privilege provision condition, information indicating the privilege provision condition and privilege identification information (privilege ID) are stored in association with each other in the privilege management table 11T. Also, in the example of FIG. 4, a privilege is indicated for each privilege ID. Examples of privilege provision conditions are shown below.

(Example 1 of privilege provision conditions)
Example 1 of privilege provision conditions is conditions regarding a store. In the example of FIG. 4, as an example of the condition regarding the store, the privilege provision condition "store A" is registered in the privilege management table 11T. Also, in the privilege management table 11T, the privilege ID "privilege ID_A" is associated with the privilege provision condition "store A". The privilege specified by the privilege ID “privilege ID_A” is “the NFT of the mascot doll of the store A”. If the store ID indicated by the target payment information matches the store ID of "store A", the privilege granting processing unit 14 determines that there is a privilege granting condition "store A" that the target payment information satisfies in the privilege management table 11T. . In this case, the privilege granting processing unit 14 acquires the privilege ID "privilege ID_A" associated with the privilege granting condition "store A" in the privilege management table 11T, and associates the acquired privilege ID "privilege ID_A" with the target payment information. .

(Example 2 of privilege provision conditions)
Example 2 of the privilege granting condition is a condition regarding merchandise. In the example of FIG. 4, as an example of the condition regarding the product, the privilege provision condition "product B" is registered in the privilege management table 11T. Also, in the privilege management table 11T, the privilege ID "privilege ID_B" is associated with the privilege provision condition "merchandise B". The privilege specified by the privilege ID “privilege ID_B” is “an idol trading card NFT appearing in the advertisement of product B”. When the product ID indicated by the target payment information matches the product ID of "product B", the privilege provision processing unit 14 determines that there is a privilege provision condition "product B" that the target payment information satisfies in the privilege management table 11T. . In this case, the privilege granting processing unit 14 acquires the privilege ID "privilege ID_B" associated with the privilege granting condition "product B" in the privilege management table 11T, and associates the acquired privilege ID "privilege ID_B" with the target payment information. .

Note that the above-described privilege granting condition example 1 and example 2 may be combined as the privilege granting condition. In this case, satisfying the privilege granting condition means satisfying both the condition regarding the store and the condition regarding the product. When the target payment information satisfies the privilege granting condition "both the store condition and the product condition", the privilege granting processing unit 14 acquires the privilege ID associated with the privilege granting condition in the privilege management table 11T. and associates the obtained privilege ID with the target payment information.

(Example 3 of privilege provision conditions)
An example 3 of privilege provision condition is a condition in which a condition relating to at least one of a store and a product and a payment period condition are combined. The payment term condition is a condition that limits the period during which payment is made. In the example of FIG. 4, as an example of a combination of a store condition and a payment period condition, a condition "store C, Within settlement period t_C" is registered in the privilege management table 11T. Also, in the privilege management table 11T, the privilege ID "privilege ID_C" is associated with the privilege provision condition "store C, within settlement period t_C". The privilege specified by the privilege ID “privilege ID_C” is “NFT of a limited-time mascot doll of store C”. If the store ID indicated by the target payment information matches the store ID of "store C" and the accounting date and time indicated by the target payment information is "within the settlement period t_C", the privilege grant processing unit 14 sets the privilege management table 11T. , it is determined that there is a privilege provision condition “store C, within payment period t_C” that the target payment information satisfies. In this case, the privilege granting processing unit 14 acquires the privilege ID “privilege ID_C” associated with the privilege granting condition “store C, within settlement period t_C” in the privilege management table 11T, and sets the acquired privilege ID “privilege ID_C” to Associate with eligible payment information.

(Example 4 of privilege provision conditions)
An example 4 of privilege provision condition is a condition in which a condition relating to at least one of a store and a product and a payment amount condition are combined. The payment amount condition is a condition that limits the payment amount. In the example of FIG. 4, as an example of a combination of a store condition and a payment amount condition, a condition "store D, payment amount p_D or more" is registered in the privilege management table 11T. Also, in the privilege management table 11T, the privilege ID "privilege ID_D" is associated with the privilege provision condition "store D, payment amount p_D or more". The privilege specified by the privilege ID “privilege ID_D” is “digital art NFT limited to store D”. If the store ID indicated by the target payment information matches the store ID of "store D" and the payment amount indicated by the target payment information is "settlement amount p_D or more", the privilege grant processing unit 14 sets the privilege management table 11T. , it is determined that there is a privilege provision condition “store D, payment amount p_D or more” that the target payment information satisfies. In this case, the privilege granting processing unit 14 acquires the privilege ID "privilege ID_D" associated with the privilege granting condition "store D, payment amount p_D or more" in the privilege management table 11T, and sets the acquired privilege ID "privilege ID_D" to Associate with eligible payment information.

In addition, the above-described privilege granting condition example 3 and example 4 may be combined as the privilege granting condition. In this case, satisfying the privilege granting condition means satisfying all of the conditions relating to at least one of the store and the product, the payment period condition, and the payment amount condition. If the target payment information satisfies the privilege granting condition "at least one of the store and the product, the settlement period condition, and the settlement amount condition", the privilege granting processing unit 14 acquires a privilege ID associated with the privilege granting condition, and associates the acquired privilege ID with the target payment information.

Note that NFT can be applied to various types of benefits. As benefits, NFTs can be applied to various types of items such as digital art, game items, trading cards, digital photographs, digital voice, digital text, and various items.

(Step S202) If there is a privilege granting condition that the target payment information satisfies among the privilege granting conditions included in the privilege management table 11T, the privilege granting processing unit 14 acquires the user ID and the privilege ID related to the target payment information and the NFT. request to the NFT management system 4.

The user ID related to the target payment information is the user ID used in the settlement related to the target payment information.
If the user ID registered for code payment in the information processing device 1 is different from the user ID registered in the NFT management system 4, the user ID used in the payment related to the target payment information is transferred to the NFT management system 4. A user ID resulting from conversion into a registered user ID may be transmitted to the NFT management system 4 . In this case, the information processing device 1 includes a user ID conversion table in which user IDs registered for code settlement are associated with user IDs registered in the NFT management system 4 .
The privilege ID related to the target payment information is the privilege ID associated with the target payment information in step S201.
Note that the privilege ID may be NFT identification information (NFT_ID) managed by the NFT management system 4 . In this case, NFT_ID is registered as the privilege ID in the privilege management table 11T.

The NFT acquisition request is an NFT corresponding to the privilege specified by the privilege ID related to the target payment information, and the user specified by the user ID related to the target payment information is the holder. This is information requesting acquisition of NFT information (token information) indicating the NFT.

The NFT management system 4 receives the user ID, privilege ID, and NFT acquisition request from the information processing device 1 .

(Step S203) Upon receiving the user ID, privilege ID, and NFT acquisition request from the information processing device 1, the NFT management system 4 executes NFT acquisition processing. NFT management system 4, in the NFT acquisition process, NFT corresponding to the privilege (hereinafter referred to as target privilege) specified by the privilege ID received from information processing device 1 (hereinafter referred to as target NFT) owner, A process of changing to a user specified by the user ID received from the information processing apparatus 1 (hereinafter referred to as a target user) is executed. As a result, the owner of the target NFT managed on the blockchain 5 is changed to the target user.
In addition, the holder of the target NFT before the change is a predetermined person on the side of granting the privilege. The holder of the target NFT before the change is, for example, a business operator (store business operator) that operates a store related to the target privilege, or a business operator (payment business operator) that operates a code payment business.
In addition, when the holder of the target NFT is changed from the store business operator or payment business operator who is the owner of the target NFT before the change to the target user, the store business operator who is the owner of the target NFT before the change or the payment The target NFT acquisition cost (crypto assets) may be paid to the business operator by the store operator or the payment operator who is not the holder of the target NFT before the change.

The NFT management system 4 generates NFT information indicating the target NFT whose owner has been changed to the target user on the blockchain 5 . The NFT information is information including metadata about the target NFT. The metadata about the target NFT has information such as the identifier, creation date and time, owner address indicating the owner (target user), privilege URL, etc. for the target NFT. The privilege URL is a URL (Uniform Resource Locator) indicating the location of an object (for example, a mascot doll of store A, etc.) for which the object NFT certifies the holder.

(Step S204) The NFT management system 4 transmits the generated NFT information to the information processing device 1 that has made the NFT acquisition request. The information processing device 1 receives NFT information from the NFT management system 4 .

(Step S205) In the information processing device 1, the privilege provision processing unit 14 transmits the NFT information received from the NFT management system 4 to the user terminal 2 of the target user.

(Step S<b>206 ) Upon receiving the NFT information from the information processing device 1 , the user terminal 2 displays the received NFT information on the display screen of its own user terminal 2 . Thereby, the user recognizes that the target NFT corresponding to the target privilege and of which the user is the holder has been acquired. The user can use the user terminal 2 to access the privilege URL indicated by the NFT information and confirm the object (for example, the mascot doll of the store A) that the object NFT certifies as the owner. Also, the user can use the user terminal 2 to access the NFT management system 4 and sell the target NFT specified by the NFT information.

It should be noted that, in the above-described embodiment, the data indicating the payment made by the payment processing unit 12 is not recorded on the blockchain 5 .

Modifications of the above-described embodiment will be described below.

(Modification 1)
The privilege provision processing unit 14 may acquire NFT information based on the payment history for each user recorded in the payment history recording unit 13 . For example, based on the payment history of each user recorded in the payment history recording unit 13, the privilege provision processing unit 14 aggregates the number of past purchases and the total amount of payment at the store indicated in the privilege provision condition for each user. Then, a user whose tally result satisfies a predetermined NFT information acquisition condition is specified, and NFT information is acquired only for the specified user.
For example, the privilege provision processing unit 14 identifies users whose attribute information satisfies predetermined NFT information acquisition conditions based on the attribute information (for example, age, address, etc.) of each user recorded in the payment history recording unit 13 . , NFT information is acquired only for the specified user.

(Modification 2)
In the information processing method exemplified in FIG. 3 described above, the information processing device 1 separately performs payment completion notification and NFT information transmission to the user terminal 2, but the payment completion notification and NFT information transmission are performed separately. You can go at the same time. For example, the privilege provision processing unit 14 transmits to the user terminal 2 data in which the notification of completion of payment made by the payment processing unit 12 and the NFT information are simultaneously displayed on the user terminal 2 .
In addition, the information processing device 1 notifies that the owner of the target NFT corresponding to the target privilege has been changed to the target user (NFT holder change), the device (store related device). Thereby, the store side can grasp the remaining number of NFTs that can be given as a privilege. The store-related device is, for example, the store terminal 3 or a store management device provided at the headquarters of the store operator. Information (for example, a communication address, etc.) of the destination store-related device is stored in advance in the information processing device 1 . The information processing device 1 may transmit the notification of NFT owner change, for example, only to the store terminal 3, may transmit only to the store management device, or may transmit to both the store terminal 3 and the store management device You may send.

(Modification 3)
Privilege granting conditions related to the target privilege may be further recorded in the blockchain 5 in association with the target NFT. The privilege granting processing unit 14 acquires NFT information indicating the NFT in which the privilege granting condition related to the target privilege is recorded on the block chain 5, and transmits the acquired NFT information to the user terminal 2 of the target user.

(Modification 4)
The shop side may bear the cost required to acquire the NFT information. In general, when acquiring NFT, a transaction fee called "gas fee" is charged. Therefore, the store will be billed for the gas cost required to acquire the target NFT. For example, when acquiring the NFT information on the target NFT, the privilege granting processing unit 14 performs the process of withdrawing the gas fee required to acquire the target NFT from the account of the store specified by the store ID indicated by the target payment related information. Run.

Also, when the user sells the target NFT, a predetermined return amount may be returned to the store that paid for the gas cost required to acquire the target NFT. For example, when the privilege provision processing unit 14 receives an NFT sale notification indicating that the target NFT has been sold from the NFT management system 4, the gas fee required to acquire the target NFT is paid. Execute the process of depositing the amount.

According to the above-described embodiment, an NFT that corresponds to a privilege associated with the use of code payment and that is owned by the user who used the code payment is acquired, and NFT information indicating the NFT is provided to the user. be. As a result, it is possible to obtain the effect that it is possible to improve the willingness to purchase by using NFT for users who use code payment.

As a result, it will be possible to improve overall service quality in commercial transaction systems that use code payments, for example. It will be possible to contribute to the promotion of sustainable industrialization and the expansion of innovation.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes and the like are included within the scope of the present invention.

For example, in the above-described embodiment, code settlement is applied as a settlement method based on the user ID, but the present invention is not limited to this. As a settlement method based on the user ID, for example, a prepaid settlement method or a postpaid settlement method such as a credit card may be applied.

Alternatively, a computer program for realizing the functions of the devices described above may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be read and executed by the computer system. Note that the “computer system” referred to here may include hardware such as an OS and peripheral devices. The "computer system" also includes the home page providing environment (or display environment) if the WWW system is used.
In addition, "computer-readable recording medium" includes writable nonvolatile memories such as flexible discs, magneto-optical discs, ROMs and flash memories, portable media such as DVDs (Digital Versatile Discs), and computer system built-in media. A storage device such as a hard disk that
