Description

The present invention relates to an information processing device and an information processing method.

Conventionally, code payments using one-dimensional barcodes or two-dimensional codes such as QR Codes (registered trademark) have been known (see, for example, Patent Document 1). Code payments can be broadly divided into two types: CPM (Consumer Presented Mode) and MPM (Merchant Presented Mode). In the CPM method, payment is made by the store, which is the sales company, reading a payment code displayed on the terminal of the user, who is the purchaser. In the MPM method, payment is made by the user's terminal reading a payment code displayed by the store.

FIG. 13 is a diagram showing an example of the configuration of a benefit management table according to an embodiment;

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 is a block diagram showing an example of the configuration of a payment system according to an embodiment. In Fig. 1, an information processing device 1 mainly executes a process related to code payment (code payment process) and a process related to awarding a bonus (bonus award process). In this embodiment, the CPM method is used for code payment. The payment code used in the CPM method may be a one-dimensional barcode or a two-dimensional code.

The information processing device 1 transmits and receives data via a communication line between the terminal (user terminal) 2 used by the user. The user terminal 2 is a portable terminal device such as a smartphone or a tablet computer (tablet PC). A terminal-side code payment application compatible with the CPM method is installed on the user terminal 2. By starting the code payment application on the user terminal 2, the user can use the user terminal 2 to pay for products using code payment under the CPM method. The product may be anything that is intended for sale, including goods and services. The product may also be a financial product.

The information processing device 1 transmits and receives data via a communication line to and from a terminal (store terminal) 3 installed in the store. The store terminal 3 is, for example, a Point-Of-Sales (POS) terminal. A store-side code payment application compatible with the CPM method is installed in the store terminal 3. By starting the code payment application on the store terminal 3, the store can use the store terminal 3 to execute code payment under the CPM method.

The information processing device 1 transmits and receives data to and from the NFT management system 4 via a communication line. The NFT management system 4 is an information processing system for managing NFTs (non-fungible tokens). The holders of the NFTs managed by the NFT management system 4 are managed on a blockchain 5. The blockchain 5 records the history of the NFTs managed by the NFT management system 4. This blockchain 5 certifies the holders of the NFTs managed by the NFT management system 4.

The NFT management system 4 may also have the functionality of an NFT marketplace. The functionality of the NFT marketplace is related to the distribution of NFTs, such as the purchase and sale of NFTs, for example, presenting sales information for NFTs, accepting requests to purchase and sell NFTs, and settling the price of NFTs.

FIG. 2 is a block diagram showing an example of the configuration of an information processing device according to this embodiment. In FIG. 2, the information processing device 1 includes a memory unit 11, a payment processing unit 12, a payment history recording unit 13, and a bonus granting processing unit 14.

Each function of the information processing device 1 is realized by the information processing device 1 having computer hardware such as a CPU (Central Processing Unit) and memory, and the CPU executing a computer program stored in the memory. The information processing device 1 may be configured using a general-purpose computer device, or may be configured as a dedicated hardware device. For example, the information processing device 1 may be configured using a server computer connected to a communication network such as the Internet. Each function of the information processing device 1 may be realized by cloud computing. The information processing device 1 may be realized by a single computer, or may be realized by distributing the functions of the information processing device 1 among multiple computers. The information processing device 1 may also be configured to open a website, for example, by using a WWW system or the like.

The memory unit 11 stores various data such as the bonus management table 11T.

The payment processing unit 12 performs code payment processing. In this embodiment, the code payment processing realizes CPM code payment. The payment processing unit 12 performs CPM code payment by coordinating with a code payment application on the terminal side and a code payment application on the store side.

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

The reward granting processing unit 14 performs a reward granting process. In this embodiment, the reward granting process grants a reward using NFT to a user who has used code payment.

Next, the information processing method according to this embodiment will be described with reference to FIG. 3. 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 in a store, the user pays for the product by code payment.

(Step S101) The user purchases an item at a store. When making a payment at the store, the user launches a code payment application on the user terminal 2 and performs an operation to display a payment code on the user terminal 2.

(Step S102) When the user terminal 2 accepts an operation to display the payment code, it transmits the user ID and a request for issuing a payment code (code issuance request) for the user to make a payment at a store to the information processing device 1. The user ID that the user terminal 2 transmits to the information processing device 1 is a user ID that has been registered in advance in the code payment application on the user terminal 2.

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

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

(Step S104) The payment processing unit 12 associates the user ID received from the user terminal 2 that requested the code issuance with the generated code information and stores them in the storage unit 11.

(Step S105) The payment processing unit 12 transmits the generated code information to the user terminal 2 that requested the code issuance.

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

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

(Step S108) When the store terminal 3 reads the payment code, it generates payment information. The payment information includes store identification information (store ID), the payment amount, and the transaction date and time. The store ID is pre-registered in the code payment application in the store terminal 3. The payment amount is the total amount of the items purchased by the user. The transaction date and time is the current date and time in the store terminal 3. The payment information may also include identification information (item ID) of the item purchased by the user.
Furthermore, the store ID may be information including identification information of the business operator that operates the store and identification information unique to each store. For example, if a P business operates stores in an X town store and a Y station store, the store ID of the X town store includes "identification information of the P business operator" common to both stores and "identification information unique to the X town store," while the store ID of the Y station store includes "identification information of the P business operator" common to both stores and "identification information unique to the Y station store."
The transaction date and time may also be the date and time when the store terminal 3 transmits payment information to the information processing device 1.

(Step S109) The store terminal 3 transmits the generated payment information and 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 the payment information and the 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 transaction date and time.

(Step S110) When the payment processing unit 12 receives the payment information and the code information from the store terminal 3, it determines whether the received code information matches the code information stored in the memory unit 11. If the received code information matches the code information stored in the memory unit 11, 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 store terminal 3.

In a payment made by the payment processing unit 12, the payment processing unit 12 executes a process of debiting the payment amount indicated by the payment information from the account of the user identified by the user ID associated with the code information in the memory unit 11. The payment processing unit 12 also executes a process of depositing the payment amount into the account of the store identified by the store ID indicated in the payment information. Here, the payment processing unit 12 may deposit the amount remaining after deducting a predetermined fee from the payment amount into the store's account.

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

(Step S112) When the user terminal 2 receives the payment completion notification from the information processing device 1, it displays on the display screen of its own user terminal 2 that the payment for the product has been completed. This allows the user to recognize that the payment for the product has been completed. When the store terminal 3 receives the payment completion notification from the information processing device 1, it displays on the display screen of its own store terminal 3 that the payment for the product has been completed. This allows the store clerk to recognize that the payment for the product has been completed.

(Step S113) When a payment is completed by the payment processing unit 12, the payment history recording unit 13 in the information processing device 1 records the history of the code payment performed by the payment processing unit 12 for that payment. The code payment history includes the user ID, store ID, transaction date and time, and payment amount. This makes it possible to tally up the number of purchases made by each store and the total payment amount for each user.
The payment history recording unit 13 may record various attribute information (e.g., age, address, etc.) of a user corresponding to a user ID in the code payment history. The attribute information of each user is registered in the information processing device 1 in association with the user ID, for example, when the user is registered.

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

The bonus granting processing unit 14 determines whether or not the bonus granting conditions contained in the bonus management table 11T include a bonus granting condition that is satisfied by the target payment information. If the result of this determination is that the bonus granting conditions are included in the bonus management table 11T and the target payment information includes a bonus granting condition, the bonus granting processing unit 14 identifies the bonus identification information (bonus ID) to be associated with the target payment information, and executes the processing of the next step S202. On the other hand, if the bonus granting conditions are not included in the bonus management table 11T and the target payment information includes a bonus granting condition, the processing unit 14 ends the procedure of FIG. 3.

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

(Example 1 of conditions for granting benefits)
Example 1 of the reward granting condition is a condition related to a store. In the example of FIG. 4, the reward granting condition "Store A" is registered in the reward management table 11T as an example of a condition related to a store. In addition, in the reward management table 11T, a reward ID "Reward ID_A" is associated with the reward granting condition "Store A". The reward specified by the reward ID "Reward ID_A" is an "NFT of Store A's mascot doll". When the store ID indicated by the target payment information matches the store ID of "Store A", the reward granting processing unit 14 determines that there is a reward granting condition "Store A" satisfied by the target payment information in the reward management table 11T. In this case, the reward granting processing unit 14 acquires the reward ID "Reward ID_A" associated with the reward granting condition "Store A" in the reward management table 11T, and associates the acquired reward ID "Reward ID_A" with the target payment information.

(Example 2 of conditions for granting benefits)
The second example of the bonus condition is a condition related to a product. In the example of FIG. 4, the bonus condition "product B" is registered in the bonus management table 11T as an example of a condition related to a product. In the bonus management table 11T, a bonus ID "bonus ID_B" is associated with the bonus condition "product B". The bonus specified by the bonus ID "bonus ID_B" is an "NFT of a trading card of an idol appearing in an advertisement for product B". When the product ID indicated by the target payment information matches the product ID of "product B", the bonus granting processing unit 14 determines that the bonus granting condition "product B" satisfied by the target payment information exists in the bonus management table 11T. In this case, the bonus granting processing unit 14 acquires the bonus ID "bonus ID_B" associated with the bonus granting condition "product B" in the bonus management table 11T, and associates the acquired bonus ID "bonus ID_B" with the target payment information.

Note that the bonus granting conditions, examples 1 and 2 above, may be combined as the bonus granting conditions. In this case, satisfying the bonus granting conditions means satisfying both the store-related conditions and the product-related conditions. When the target payment information satisfies the bonus granting conditions "both the store-related conditions and the product-related conditions," the bonus granting processing unit 14 obtains the bonus ID associated with the bonus granting conditions in the bonus management table 11T, and associates the obtained bonus ID with the target payment information.

(Example 3 of conditions for granting benefits)
Example 3 of the bonus granting condition is a condition that combines a condition related to at least one of the store and the product with a payment period condition. The payment period condition is a condition that limits the period during which payment is made. In the example of FIG. 4, as an example of a condition that combines a store-related condition and a payment period condition, a condition "Store C, within payment period t_C" that combines a store-related condition "Store C" with a payment period condition "within payment period t_C" is registered in the bonus management table 11T. In addition, in the bonus management table 11T, a bonus ID "Bonus ID_C" is associated with the bonus granting condition "Store C, within payment period t_C". The bonus identified by the bonus ID "Bonus ID_C" is "Store C's limited-edition mascot doll NFT." The bonus granting processing unit 14 determines that the bonus granting condition "store C, within payment period t_C" is satisfied by the target payment information in bonus management table 11T when the store ID indicated in the target payment information matches the store ID of "store C" and the transaction date and time indicated in the target payment information is "within payment period t_C". In this case, the bonus granting processing unit 14 obtains the bonus ID "bonus ID_C" associated with the bonus granting condition "store C, within payment period t_C" in bonus management table 11T, and associates the obtained bonus ID "bonus ID_C" with the target payment information.

(Example 4 of the conditions for granting benefits)
Example 4 of the bonus granting condition is a condition that combines a condition related to at least one of the store and the product with a payment amount condition. The payment amount condition is a condition that limits the payment amount. In the example of FIG. 4, as an example of a condition that combines a store-related condition and a payment amount condition, a condition "Store D, payment amount p_D or more" that combines a store-related condition "Store D" with a payment amount condition "payment amount p_D or more" is registered in the bonus management table 11T. Also, in the bonus management table 11T, a bonus ID "Bonus ID_D" is associated with the bonus granting condition "Store D, payment amount p_D or more". The bonus identified by the bonus ID "Bonus ID_D" is "NFT of digital art exclusive to Store D". The bonus granting processing unit 14 determines that the bonus granting condition "Store D, payment amount p_D or more" is satisfied by the target payment information in bonus management table 11T when 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 "payment amount p_D or more." In this case, the bonus granting processing unit 14 obtains the bonus ID "Bonus ID_D" associated with the bonus granting condition "Store D, payment amount p_D or more" in bonus management table 11T, and associates the obtained bonus ID "Bonus ID_D" with the target payment information.

Note that the bonus granting conditions examples 3 and 4 above may be combined as bonus granting conditions. In this case, satisfying the bonus granting conditions means satisfying all of the following conditions: a condition related to at least one of the store and the product, a payment period condition, and a payment amount condition. When the target payment information satisfies the bonus granting conditions "all of the conditions related to at least one of the store and the product, a payment period condition, and a payment amount condition," the bonus granting processing unit 14 obtains a bonus ID associated with the bonus granting condition in the bonus management table 11T, and associates the obtained bonus ID with the target payment information.

Note that NFTs can be applied to a variety of different types of rewards. Rewards can include digital art, game items, trading cards, digital photographs, digital audio, digital text, and a variety of other items.

(Step S202) If the target payment information satisfies any of the bonus granting conditions contained in the bonus management table 11T, the bonus granting processing unit 14 sends the user ID and bonus ID related to the target payment information and an NFT acquisition request to the NFT management system 4.

The user ID related to the target payment information is the user ID used in the payment related to the target payment information.
When 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 resulting from conversion from the user ID used in the payment related to the target payment information to the user ID registered in the NFT management system 4 may be transmitted to the NFT management system 4. In this case, the information processing device 1 has a user ID conversion table in which the user ID registered for code payment and the user ID registered in the NFT management system 4 are associated with each other.
The privilege ID related to the target payment information is the privilege ID associated with the target payment information in step S201 above.
The benefit ID may be identification information (NFT_ID) of the NFT managed by the NFT management system 4. In this case, the NFT_ID is registered as the benefit ID in the benefit management table 11T.

The NFT acquisition request is information requesting the acquisition of NFT information (token information) indicating an NFT that corresponds to a benefit identified by a benefit ID related to the target payment information and that is recorded on the blockchain 5 as being owned by a user identified by a user ID related to the target payment information.

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

(Step S203) When the NFT management system 4 receives the user ID, the benefit ID, and the NFT acquisition request from the information processing device 1, it executes an NFT acquisition process. In the NFT acquisition process, the NFT management system 4 executes a process to change the holder of the NFT (hereinafter referred to as the target NFT) corresponding to the benefit (hereinafter referred to as the target benefit) identified by the benefit ID received from the information processing device 1 to the user (hereinafter referred to as the target user) identified by the user ID received from the information processing device 1. As a result, the holder of the target NFT managed on the blockchain 5 is changed to the target user.
The holder of the target NFT before the change is a specified party that grants the benefit. The holder of the target NFT before the change is, for example, a business operator that operates a store related to the target benefit (store operator) or a business operator that operates a code payment business (payment operator).
In addition, when the holder of the target NFT is changed from a store operator or payment service provider that is the holder of the target NFT before the change to a target user, the target NFT acquisition cost (cryptocurrency) may be paid to the store operator or payment service provider that is the holder of the target NFT before the change by a store operator or payment service provider that 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 regarding the target NFT. The metadata regarding the target NFT includes information regarding the target NFT, such as an identifier, creation date and time, an owner address indicating the owner (target user), and a bonus URL. The bonus URL is a uniform resource locator (URL) indicating the location of the object (e.g., a mascot doll for store A) whose owner the target NFT certifies.

(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 the NFT information from the NFT management system 4.

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

(Step S206) When the user terminal 2 receives the NFT information from the information processing device 1, it displays the received NFT information on the display screen of the user terminal 2. This allows the user to recognize that the target NFT, which corresponds to the target benefit and of which the user is the owner, has been acquired. The user can use the user terminal 2 to access the benefit URL indicated in the NFT information and confirm the object (e.g., store A's mascot doll) that proves the owner of the target NFT. The user can also use the user terminal 2 to access the NFT management system 4 and sell the target NFT identified by the NFT information.

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

Below, we will explain some variations of the above-mentioned embodiment.

(Variation 1)
The bonus granting processing unit 14 may acquire NFT information based on the payment history of each user recorded in the payment history recording unit 13. For example, the bonus granting processing unit 14 tally up the number of past purchases and the total payment amount at the store indicated in the bonus granting conditions for each user based on the payment history of each user recorded in the payment history recording unit 13, identifies users whose tallying results satisfy predetermined NFT information acquisition conditions, and acquires NFT information limited to the identified users.
For example, the bonus granting processing unit 14 identifies users whose attribute information meets specified NFT information acquisition conditions based on the attribute information for each user (e.g., age, address, etc.) recorded in the payment history recording unit 13, and acquires NFT information only from the identified users.

(Variation 2)
3, the information processing device 1 separately notifies the user terminal 2 of the completion of payment and transmits the NFT information, but the payment completion notification and the NFT information may be transmitted simultaneously. For example, the bonus granting processing unit 14 transmits data to the user terminal 2 that displays the completion notification of the payment performed by the payment processing unit 12 and the NFT information simultaneously on the user terminal 2.
The information processing device 1 may notify a device (store-related device) related to the store where the payment for the target benefit was made that the holder of the target NFT corresponding to the target benefit has been changed to the target user (NFT holder change). This allows the store to know the remaining number of NFTs that can be granted as a benefit. The store-related device is, for example, the store terminal 3 or a store management device installed at the headquarters of the store operator. Information on the destination store-related device (for example, a communication address, etc.) is stored in advance in the information processing device 1. The information processing device 1 may send the notification of the NFT holder change, for example, only to the store terminal 3, only to the store management device, or to both the store terminal 3 and the store management device.

(Variation 3)
A reward granting condition related to the target reward may be further recorded in association with the target NFT on the blockchain 5. The reward granting processing unit 14 acquires NFT information indicating an NFT in which a reward granting condition related to the target reward is further recorded on the blockchain 5, and transmits the acquired NFT information to the user terminal 2 of the target user.

(Variation 4)
The store may bear the costs required to acquire the NFT information. Generally, a transaction fee called a "gas fee" is charged when acquiring an NFT. For this reason, the gas fee required to acquire the target NFT is charged to the store. For example, when acquiring NFT information related to the target NFT, the bonus granting processing unit 14 executes a process of debiting the gas fee required to acquire the target NFT from the account of the store identified by the store ID indicated by the target payment-related information.

In addition, when a user sells a target NFT, a specified refund amount may be returned to the store that covered the gas costs required to acquire the target NFT. For example, when the bonus granting processing unit 14 receives an NFT sale notification from the NFT management system 4 indicating that the target NFT has been sold, the bonus granting processing unit 14 executes a process of depositing the specified refund amount into the account of the store that covered the gas costs required to acquire the target NFT.

According to the above-described embodiment, an NFT corresponding to a benefit associated with the use of code payment, the NFT being held by the user who used the code payment, is acquired, and NFT information indicating the NFT is provided to the user. This has the effect of increasing purchasing motivation for users who use code payment by utilizing the NFT.

Furthermore, this will make it possible to improve the overall service quality in commercial transaction systems that use code payments, for example, and contribute to Goal 9 of the United Nations-led Sustainable Development Goals (SDGs), which is to "build resilient infrastructure, promote sustainable industrialization and foster innovation."

The above describes an embodiment of the present invention in detail with reference to the drawings, but the specific configuration is not limited to this embodiment and includes design modifications within the scope of the present invention.

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

Also, a computer program for implementing the functions of each of the above-mentioned devices may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed. Note that the "computer system" referred to here may include hardware such as an OS and peripheral devices. In addition, if a WWW system is used, the "computer system" also includes the home page providing environment (or display environment).
In addition, the term "computer-readable recording medium" refers to a storage device such as a flexible disk, a magneto-optical disk, a ROM, a writable non-volatile memory such as a flash memory, a portable medium such as a DVD (Digital Versatile Disc), or a hard disk built into a computer system.

Furthermore, the term "computer-readable recording medium" includes devices that retain a program for a certain period of time, such as volatile memory (e.g., DRAM (Dynamic Random Access Memory)) within a computer system that serves as a server or client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line.
The program may be transmitted from a computer system in which the program is stored in a storage device or the like to another computer system via a transmission medium, or by a transmission wave in the transmission medium. Here, the "transmission medium" that transmits the program refers to a medium that has a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.
The program may be a program for implementing some of the above-mentioned functions, or may be a so-called differential file (differential program) that can implement the above-mentioned functions in combination with a program already recorded in the computer system.
