<Compliance with legal matters>
Note that the disclosure provided herein is subject to compliance with the legal requirements of the implementing country required for the practice of this disclosure, such as confidentiality of communications.

Embodiments for implementing a program, an information processing method, a display method, a terminal, a server, etc. according to the present disclosure will be described with reference to the drawings.

<Overview>
In recent years, as applications (application software) related to network services, there are applications such as applications for making payments and settlements using electronic money (payment applications/settlement applications) and applications for sending/receiving electronic money (remittance applications). In addition, applications that integrate some or all of these applications' functions are becoming popular, and users of the terminal 20 can use these applications to receive various services related to electronic money. is coming.

“Electronic money” is electronic money that is distinguished from physical money, and means electronic money owned by the terminal 20 or the user of the terminal 20 managed by the various applications described above.

Note that electronic money may be expressed as “electronic money” or “digital currency (digital currency)”, or may not be expressed as such.
Also, as "electronic money (electronic money)" or "digital currency (digital currency)", a legal currency may be used, or a virtual currency may be used.
Also, "electronic currency (electronic money)" and "digital currency (digital currency)" may include cryptocurrency (cryptographic assets).
Virtual currency may also include physical money such as coupons.

In this specification, the expression "by communication I/F" is appropriately used. This indicates that the device transmits and receives various types of information and data via the communication I/F (via the communication unit) based on the control of the control unit (processor, etc.), as an example and not a limitation. .

Further, in this specification, "payment" means electronic payment (electronic payment). An example of this is electronic payment using electronic money.

Further, in this specification, "processing related to payment" is, as an example and not a limitation, a process related to payment executed by the terminal 20, which is a process of acquiring code information for making payment from a server or the like (code information and processing to receive the generated code information from the server, etc.), processing to display the acquired code information, payment results (including payment notification) from the server, etc. It includes processing that is somehow related to making a payment, such as processing to acquire, more specifically, general processing that is executed by the terminal 20 as processing that is related to making a payment.

In this specification, "code information" includes a code image, information stored in the code image by encoding or the like (stored information), or information to be stored (stored information). . The stored information and information to be stored include, by way of example and not limitation, tokens, which will be described in detail below.

In addition, in this specification, the code payment, which is a payment method/settlement method using a code (code information), is not limited to but an example,
(1) User presentation type (2) Store presentation type Two types are exemplified.

In the user presentation type, as an example and not a limitation, a user (user of the terminal 20) presents a payment code displayed on the display unit 24 of the terminal 20 to a store clerk (as an example, not a limitation, a member store). The code is then read by the code reader 58 of the store code reader device 50 to make the payment.
The store presentation type is, for example and not limitation, a payment store code presented or posted at a store (as an example, but not limited to, a member store) when the user uses the camera 27 of the terminal 20 or a code reader (a code reader of the payment application). including.) to read and make payments.

In the following description, the code presented by the user and displayed on the display unit 24 of the terminal 20 is referred to as "payment code", but may be referred to as "user presented code" or the like.
Also, hereinafter, the code read by the terminal 20 in the store presentation type is referred to as the "payment store code", but it may be referred to as the "store presentation type code" or the like.

Also herein, as account-based payments, by way of example and not limitation:
(A) Common account settlement (B) Account linked settlement Two types are exemplified.
An “account” is an account of an application (payment application/settlement application) for performing payment/settlement using electronic money as an example and not as a limitation.

Common account settlement is a method of making settlement based on an account that can be used commonly by a plurality of users (hereinafter referred to as "common account"). This settlement is called "common account settlement". Common account settlement is realized by using a common wallet. A "common wallet" is a form of electronic money account set up by a plurality of users, and constitutes one virtual wallet.
A common account settlement can also be regarded as a settlement by a user using an account common to a plurality of users (one common account).
The common account payment may be expressed as a common wallet payment.

Account linkage settlement is a method of settlement by linking multiple accounts. Linking accounts means linking multiple accounts so that they can be used for payment. Linking accounts is called "account linking", and settlement using account linking is called "account linking settlement".
In this case, a plurality of accounts of one user may be linked, or accounts of a plurality of users may be linked. In other words, other people's accounts are not necessarily required for linking, and it is possible to link multiple accounts of one's own as an example and not as a limitation.

In order to realize account-linked settlement, as a non-limiting example, multiple accounts are associated, and as a non-limiting example, the process of setting settlements to be made in equal installments from each linked account ( account linkage process).
Account-linked settlement can also be understood as settlement using a different account (your own account or someone else's account) in addition to your own account.
Account linkage may also be expressed as wallet linkage. Also, account-linked settlement may be expressed as wallet-linked settlement.

In the following, as an example only, an embodiment will be described on the assumption that a plurality of users, such as friends or associates, all make payments for shopping or the like.

Common account settlement basically involves making a settlement from one account that is assumed to be shared by a plurality of users. It also describes a method for settlement based on

Also, account linkage can be performed either (B-1) before making a payment or (B-2) when making a payment, as an example and not a limitation.
(B-1) Prior to making a payment, as an example, not a limitation, it can be applied when post-payment (adjustment by splitting the bill as an example, not a limitation) is troublesome.
(B-2) When making a payment, as an example, not as a limitation, if the balance of the account set as the account for settlement at the time of payment (your account as an example, not as a limitation) is insufficient. can be applied to In this case, as an example and not a limitation, settlement can be performed by linking accounts with other users' accounts.

In common account settlement, since a common account is used for multiple users, the details will be described later, but if one user pays for another user's payment and settles, ex post settlement (liquidation ) may be required. In other words, at some point after the payment is completed, it may be necessary to adjust the amount of money for each user, such as remittance processing/receipt processing.
On the other hand, in account linked settlement, after obtaining the permission of the user of the linked account or obtaining permission on the spot, the amount will be consumed from each account, so that the settlement will be made after the fact. processing is basically unnecessary.

Based on the above, each embodiment of "common account settlement" and "account linked settlement" will be described.

Note that "collaboration" includes the meaning of doing things together for one purpose. Therefore, in the sense that a plurality of users make a payment together, it can be said that the common account payment and the account linked payment have the same purpose.

Each user management data stores, by way of example and not limitation, a payment application ID and an electronic money account balance.

Here, the common wallet will be described in detail with reference to the common wallet management database 157. FIG.

A common wallet is a form of electronic money account pre-established by multiple users of a payment application prior to making a payment.

A common wallet allows multiple users to make payments using the balance. A user who can use the common wallet is hereinafter referred to as a "common wallet member".

In order to use the common wallet, the user first performs an operation to generate the common wallet. This generation requires, by way of example and not by way of limitation, information identifying the co-wallet member's electronic money account (by way of example and not by way of limitation, payment application ID).

The common wallet management database 157 is a database for the server 10 to manage common wallets, and an example of the data configuration of the first common wallet management database 157A is shown in FIG. 1-7.
Common wallet management data is stored in the first common wallet management database 157A as management data for each common wallet ID for uniquely identifying a common wallet.

The common wallet balance is the balance of electronic money used for payment using the common wallet identified by the common wallet ID.
The common wallet member ID is the payment application ID of the common wallet member, specified when creating the common wallet.

It is also possible to add a new common wallet member by adding the payment application ID to the common wallet member ID after the common wallet is generated. Also, multiple payment application IDs owned by the same user may or may not be stored in the common wallet member ID.

When a common wallet is created, its common wallet balance is "0". Before making payments, common wallet members transfer electronic money from their respective electronic money accounts to the common wallet to increase the common wallet balance.

The common wallet member can also charge the common wallet (convert to electronic money and remit) from an external financial institution account registered with the payment service (as an example, not a limitation, a bank account).

When the common wallet becomes unnecessary, a common wallet destruction operation is performed to cancel the existing common wallet. When the common wallet destruction operation is executed, the amount obtained by dividing the common wallet balance by the number of common wallet members (equal division) is transferred to each electronic money account of the common wallet members. After the common wallet balance becomes "0", the record of the common wallet management data is deleted from the first common wallet management database 157A.

<Processing>
(1) User Presented Code Payment FIGS. 1-8 and 1-9 are flowcharts showing an example of the flow of processing executed by each device in this embodiment. From the left side, the payment processing executed by the control unit 21 of the terminal A (as an example, not limitation, the terminal 20 of the user A.A), the payment management processing executed by the control unit 11 of the server 10, the store POS system (in the limitation As an example, an example of the store payment processing executed by the control unit 51 of the store code reader device 50, which is a component of the store POS system 40) of the member store S1, is shown. This processing is an example of processing related to user-provided code payment.

As an example, user A. A's terminal 20 (terminal A) and user B.A. An electronic money account that can be used with B's terminal 20 (terminal B) will be described as a common wallet. Actually, the number of terminals that can pay using the common wallet is not limited to two, but the processing is the same as that of terminal B, so the illustration is omitted in this specification.

Note that this processing is merely an example of processing for realizing the technique of the present disclosure, and is not limited to this processing. Another step may be added to this process, or some steps may be omitted (deleted).
This is the same for each flowchart (process) described below.

Serial numbers of processes executed by each device are described in the drawings, but are omitted in the specification. The same applies to the following examples.

First, the control unit 21 of terminal A transmits common wallet creation/selection information to the server 10 via the communication I/F 22 (A100).

Specifically, information for selecting a common wallet that can be used from terminal A (as a non-limiting example, a common wallet ID) is transmitted to the server 10 via the communication I/F 22 . A selectable common wallet ID may be received from the server 10 via the communication I/F 22 in this step, or may be previously stored in the storage unit 28 .

Also, if there is no common wallet that can be used from terminal A, information for creating a new common wallet is sent to the server 10 via the communication I/F 22 . Here, the information for creating a new common wallet includes, as a non-limiting example, the account information of the members that make up the common wallet (as a non-limiting example, the payment applications of users A.A. and B.B.). ID), the name of the common wallet, and the initial remittance amount to the common wallet.

When information for selecting a common wallet or information for newly creating a common wallet is received from terminal A via communication I/F 14, control unit 11 of server 10 receives the requested common wallet ID or creates a new common wallet. and generates a payment token that authorizes payment from the wallet based on a common wallet ID that is uniquely assigned (without duplication) by the control unit 11 .

Hereinafter, a payment token that authorizes payment from a common wallet balance linked to a common wallet ID is referred to as a "common wallet payment token". Here, the common wallet payment token is identified, by way of example and not limitation, by an integer value of a predetermined number of digits (12 digits as an example and not limitation). Also, the common wallet payment token may or may not be a token with an expiration date that allows authorization only within a predetermined period of time after generation (eg, "5 minutes", not as a limitation).

When the common wallet payment token is generated, the control unit 11 of the server 10 generates common wallet code information, which is code information including the common wallet payment token. The common wallet code information includes, by way of example and not limitation, a payment code (image information) that encodes the identifier of the common wallet payment token as a one-dimensional code (barcode, etc.) or a two-dimensional code (QR code, etc.).

Note that if the common wallet payment token has an expiration date, the common wallet code information may include the expiration date. It may also include the name of the common wallet from which the common wallet payment token was generated.

After that, the control unit 11 of the server 10 transmits the common wallet code information to the terminal A through the communication I/F 14 (S100a).

Upon receiving the common wallet code information from the server 10 through the communication I/F 22, the control unit 21 of terminal A displays the received common wallet code information on the display unit 24 (A110a). Specifically, as the common wallet code information, the payment code is displayed on the display unit 24 as an example and not as a limitation.
When the common wallet code information includes the identifier and expiration date of the common wallet payment token, the control unit 21 of terminal A may or may not display the identifier and expiration date.

Also, if the common wallet payment token expires while the payment code is being displayed, the control unit 21 of terminal A transmits information requesting regeneration of the common wallet payment token to the server 10 via the communication I/F 22. may or may not.
In this case, the control unit 21 of the server 10 regenerates the common wallet payment token and the common wallet code information, and transmits the common wallet code information to the terminal A via the communication I/F 14 . When the common wallet code information regenerated from the server 10 is received by the communication I/F 22, the control unit 21 of the terminal A can cause the display unit 24 to redisplay the payment code and the expiration date. can.

Next, the control unit 11 of the server 10 transmits common wallet information, which is information about the common wallet in which the common wallet payment token is generated, to the terminal A via the communication I/F 14 (S110). Common wallet information includes, by way of example and not limitation, common wallet balances.

When the common wallet information is received from the server 10 through the communication I/F 22, the control unit 21 of terminal A displays the received common wallet information on the display unit 24 (A120). Specifically, as the common wallet information, the common wallet balance is displayed in addition to the display unit 24 as an example and not as a limitation.

The control unit 51 of the store code reader device 50 executes store payment processing, and based on the operation of the input/output unit 52 of the store code reader device 50, a predetermined planned settlement amount (not limited to, but as an example "3,000 yen") ) is input to the control unit 51 . Then, the control section 51 of the store code reader device 50 uses the code reader 58 to read the payment code displayed on the display section 24 of the terminal A (P140). In this case, since the payment code displayed on the display unit 24 is associated with the common wallet payment token, the reading result of the code reader 58 includes the common wallet payment token as the payment token.

The control unit 51 of the shop code reader device 50 receives the payment request information including the shop ID, the planned payment amount, and the payment token (in this case, the common wallet payment token) by way of the communication I/F 54 as an example and not limitation. Send to server 10 (P150).

When payment request information is received from the store code reader device 50 via the communication I/F 14, the control unit 11 of the server 10 retrieves the common wallet ID from the requested common wallet payment token, and sends the common wallet to the store. A settlement process is executed to pay the scheduled settlement amount with the member store specified by the ID (S170a).

The control unit 11 of the server 10 transmits payment result information including the success or failure of the payment processing and the common wallet balance after the payment processing to the terminal A and the store code reader device 50 via the communication I/F 14 as an example and not limitation. It transmits (S180a) and ends the process.
Upon receiving the payment result information from the server 10 via the communication I/F 22, the control unit 21 of terminal A causes the display unit 24 to display the payment result information (A180), and ends the process.
Further, upon receiving payment result information from the server 10 via the communication I/F 54, the control unit 51 of the store code reader device 50 causes the display unit 53 to display the payment result information (P160), and ends the process.

(2) Store presentation type code payment In the following, "payment store code" is used as an example, not a limitation, as member store identification information for identifying a member store (a store uniquely assigned to a member store as an example, not a limitation). It will be described as a code (one-dimensional code or two-dimensional code) including an ID).

On the other hand, if the settlement fails in the settlement process (S260a: NO), the control unit 11 of the server 10, as an example, not as a limitation, informs the user that the settlement has failed and the insufficient settlement balance in the common wallet in that case. Insufficient settlement balance information including the payment balance is transmitted to the terminal A and the shop code reader device 50 via the communication I/F 14 (S270a).

After A130, when payment balance shortage information is received from the server 10 via the communication I/F 22 (A270a: YES), the control unit 21 of terminal A causes the display unit 24 to additionally display the received payment balance shortage information ( A280). Further, the control unit 21 of the terminal A causes the storage unit 28 to store the amount of insufficient payment balance included in the received insufficient payment balance information (A290).

After that, as an example and not a limitation, based on an operation input (an operation input to the input/output unit 23) for the user account information displayed on the display unit 24 together with the insufficient settlement balance information, the control unit 21 of the terminal A communicates payment request information requesting the server 10 to pay the shortfall from his (user AA's) electronic money account balance and settle from the common wallet balance and his own electronic money account balance. /F22 to send to the server 10 (A295).

Upon receiving payment request information from terminal A through communication I/F 14, control unit 11 of server 10 executes payment processing (S170c). Specifically, as a non-limiting example, the common wallet balance is reduced to "0", and the shortfall is transferred to user A. Subtract from A's electronic money account balance.

After that, the control unit 11 of the server 10 sends the payment result information including various information included in the payment completion screen of FIG. (S180c), and the process ends.

On the other hand, if the payment balance shortage information is not received from the server 10 (A270a: NO), the control unit 21 of terminal A receives the payment result information from the server 10 via the communication I/F 22, and shifts the process to A180.

After P110, when payment balance shortage information is received from the server 10 via the communication I/F 54 (P120: YES), the control unit 51 of the shop code reader device 50 causes the display unit 53 to display the payment balance shortage information (P130). . After receiving the payment result information from the server 10, the control unit 51 of the store code reader device 50 shifts the processing to P160.

<Display of payment balance shortage information>
"Insufficient payment balance information is displayed" means "after the insufficient payment balance information is displayed" or "when the insufficient payment balance information is displayed once", and does not necessarily mean that the insufficient payment balance information is still displayed. It does not require that it has been done.
In other words, "the input to the display unit 24 where the insufficient balance information is displayed" is
(1) After the insufficient payment balance information is displayed, input is made to the display unit 24 while the insufficient payment balance information is being displayed. (2) After the insufficient payment balance information is displayed, the insufficient payment balance information is displayed. is hidden, and an input is made to the display unit 24 after that.
This also applies to the embodiments described below.

<Input to terminal>
In the above process, an example is shown in which the selection of whether or not to pay the shortfall from the user account (electronic money account) of the user of the terminal 20 is realized based on the operation input to the input/output unit 23 of the terminal 20. It is not limited to this. This may be achieved by sound input (including voice input) to the microphone 25 of the terminal 20, or may not be implemented.

The integrated account management database 159 is a database for the server 10 to manage integrated accounts, and an example of its data configuration is shown in FIG. 5-2.
The integrated account management database 159 stores integrated account management data as management data for each integrated account.

Each integrated account management data includes, as a non-limiting example, an integrated account ID that is an example of identification information for identifying the integrated account, and an integrated account member ID that indicates the user's account included in the integrated account. is stored. The integrated account member ID stores the account of the payment application integrated with the integrated account (including the user's payment application ID, common wallet ID, etc.).

In Figure 5-2, by way of example and not limitation, the unified account identified by "UN0001" consists of "U0001" (i.e. user A.A) and "S0001" (i.e. common wallet "Camp Funds"). shown to be

<Display screen example>
FIG. 5-3 shows that the icon indicated as "code payment" on the camp fund payment screen of FIG. It is a figure which shows an example of the code|cord payment screen (before integration) displayed when touch operation is carried out by A. FIG.
The screen in FIG. 5-3 is almost the same as the screen in FIG. 3-4, but a part of the display in the camping fund code payment area 2421 is different.

In the camp fund code payment area 2421 in FIG. 3-4, the checkmark button CN2 and the words "Remittance from own wallet" are displayed, and the balance ("25,000 yen" in this example) is displayed next to it. However, in the camp fund code payment area 2421 in FIG. 5-3, as information for integrating the common wallet of the camp fund with your own wallet, you can execute the integration along with the words "integrate with your own wallet". A slide button CN7 for selecting (switching) whether or not is arranged. Underneath it, the characters "my wallet" are newly displayed, and next to it, your electronic money account balance ("25,000 yen" in this example) is displayed.

The slide button CN7 is an image having an ellipse and a circle inside the ellipse. For example, when the circle is touched or slid, the state changes to the state where the circle is positioned at the right end of the ellipse (“ON” in this example), and the color inside the ellipse is displayed in reverse.

FIG. 5-4 is a diagram showing an example of the code information updating screen displayed when the slide button CN7 is operated on the code payment screen (before integration) of FIG. 5-3.
FIG. 5-4 differs from FIG. 5-3 in that the slide button CN7 in the camping fund code payment area 2421 is in the "ON" state, and the code information is being updated in the camping fund code payment area 2421. Updating information CJK indicating that there is an update is superimposed on the display. In the updating information CJK, two rotating arrows indicating that the code information is being updated are displayed in the center, and the characters "Code information is being updated..." are displayed below them.

That is, at the top of the camping fund code payment area 2421, a wallet image, the name of the common wallet (camping fund), "+" indicating addition, and the wallet image and characters of own wallet are displayed. Along with this, the balance after the integration ("26,000 yen" in this example) is displayed by adding and integrating the common wallet (camping fund) and the own wallet.

Also, the payment code displayed in the camp fund code payment area 2421 in FIG. 5-5 is different from the payment code in FIG. 5-3 due to account integration.

User A. of terminal 20 . As described above, A presents the code payment screen to the store clerk at the code register, and makes the code payment by having the store code reader read the payment code. When the payment processing by the server 10 is completed, a code payment completion screen similar to that shown in FIG. 3-7 is displayed.

<Processing>
5-6 to 5-7 are flowcharts showing an example of the flow of processing executed by each device in the embodiment. From the left side, the payment processing executed by the control unit 21 of the terminal A (as an example, not limitation, the terminal 20 of the user A.A), the payment management processing executed by the control unit 11 of the server 10, the store POS system (in the limitation As an example, an example of the store payment processing executed by the control unit 51 of the store code reader device 50, which is a component of the store POS system 40) of the member store S1, is shown. This processing is an example of processing related to user-provided code payment.

The control unit 21 of terminal A controls, by way of example and not by way of limitation, user A . When the electronic money account balance of user A is displayed in addition to the display unit 24 (A130), user A.A. A button having a function of selecting whether or not to execute payment by an integrated account summing the electronic money account balance of A and the common wallet balance is displayed on the display unit 24 (A450a).

Based on the user's operation on the input/output unit 23 of terminal A, when execution of payment by the integrated account is selected (A450a: YES), the control unit 21 of terminal A sends the account integration request information to the communication I/F 22. to the server 10 (A460).
If execution of payment by the integrated account is not selected (A450a: NO), the control unit 21 of terminal A receives payment result information from the server 10 via the communication I/F 22, and performs step A180 in FIG. 1-9. Run.

When account integration request information is received from terminal A via communication I/F 14 (S470a: YES), control unit 11 of server 10 executes account integration processing (S480).
If the account integration request information is not received (S470a: NO), the control unit 11 of the server 10 receives payment request information from the store code reader device 50, and executes step S170a in FIG. 1-9.

In the account integration process, the control unit 11 of the server 10 adds a record of integrated account management data having a unique integrated account ID to the integrated account management database 159, and adds user A.A. to the integrated account member ID of the record. Store A's payment application ID and the common wallet ID of the common wallet.

Then, the control unit 11 of the server 10 generates a payment token that authorizes payment from the balance of the integrated account linked to the integrated account ID. Hereinafter, this token will be referred to as the "integrated account payment token".
Here, the balance of the integrated account is the total balance of electronic money associated with the payment application ID and common wallet ID stored in the integrated account member ID.
Also, the Integrated Account Payment Token, like the Common Wallet Payment Token, is identified by an integer value of a predetermined number of digits (12 digits by way of example and not limitation) by way of example and not limitation. An integration account payment token may or may not be a token with an expiration date.

When the integrated account payment token is generated by the account integration process, the control unit 11 of the server 10 generates integrated account code information, which is code information including the integrated account payment token. Integrated account code information includes, by way of example and not limitation, a payment code (image information) that encodes the identifier of the integrated account payment token as a one-dimensional code (barcode) or two-dimensional code (QR code).
In addition, when the integrated account payment token has an expiration date, the expiration date may be included in the integrated account code information.

Then, the control unit 11 of the server 10 transmits the integrated account code information to the terminal A through the communication I/F 14 (S490a).

When the account integration request information is not received from the terminal A via the communication I/F 14 (S470a: NO), the control unit 11 of the server 10 receives the payment request information from the store code reader device 50 via the communication I/F 14, The step of S170a in FIG. 1-9 is executed.

When the integrated account code information is received from the server 10 via the communication I/F 22, the control unit 21 of terminal A updates and displays the payment code on the display unit 24 based on the received integrated account code information (A470a).
If the integrated account code information includes the identifier and expiration date of the integrated account payment token, the control unit 21 of terminal A may update and display the identifier and expiration date.

The control section 51 of the shop code reader device 50 uses the code reader 58 to read the payment code displayed on the display section 24 of the terminal A (P140). In this case, since the payment code displayed on the display unit 24 is associated with the integrated account payment token, the read result of the code reader 58 includes the integrated account payment token as the payment token.

Control unit 51 of store code reader device 50 receives settlement request information including, for example and not limitation, a store ID, an estimated settlement amount, and a payment token (integrated account payment token in this case) via communication I/F 54. Send to server 10 (P150).

Upon receiving payment request information from the store code reader device 50 via the communication I/F 14, the control unit 11 of the server 10 executes integrated account payment processing (S500a).
In the integrated account settlement process, the control unit 11 of the server 10 retrieves the integrated account ID from the requested integrated account payment token. The control unit 11 of the server 10 further points to the integrated account member ID based on the integrated account member ID (here, the payment application ID of user A.A and the common wallet ID of the common wallet) linked to the integrated account ID. User A.I. Using the total amount of A's electronic money account balance and common wallet balance, a settlement process is executed to pay the scheduled settlement amount with the member store specified by the store ID to the integrated account.

If the settlement with the integrated account succeeds, the control unit 11 of the server 10 reduces the common wallet balance by the expected settlement amount. If the balance of the common wallet is less than the planned settlement amount, the balance of the common wallet is reduced to "0" and the shortfall is paid to user A. Subtract from A's electronic money account balance.

It should be noted that if the settlement with the integrated account is successful, the control unit 11 of the server 10 confirms that the user A. A's electronic money account balance is reduced by the planned settlement amount, and if user A.A. If the electronic money account balance of user A is less than the expected settlement amount, user A. A's electronic money account balance may be reduced to "0" and the shortfall may be deducted from the common wallet balance, or not.

Next, the control unit 11 of the server 10 transmits payment result information including the success or failure of the payment processing and the integrated account balance after the payment processing to the store code reader device 50 via the communication I/F 14 as an example and not limitation. (S510).

In addition, the control unit 11 of the server 10, as an example and not a limitation, determines the success or failure of the payment process, the electronic money account/common wallet balance that constitutes the integrated account after the payment process, and the payment amount in the electronic money account/common wallet. is sent to terminal A via the communication I/F 14 (S520), and the process ends.

Upon receiving the payment result information from the server 10 via the communication I/F 54, the control unit 51 of the store code reader device 50 causes the display unit 53 to display the payment result information (P160), and ends the process.

Upon receiving the integrated account settlement result information from the server 10 via the communication I/F 22, the control unit 21 of terminal A causes the display unit 24 to display the integrated account settlement result information (A480), and ends the process.

<Seventh Modification (1)>
In the seventh embodiment, the code settlement presented by the user has been described, but the present invention is not limited to this. Specifically, a code payment presented at a store may be used.

FIG. 7B is a flowchart showing an example of the flow of processing executed by each device in this modified example. From the left side, an example of payment processing executed by the control unit 21 of the terminal A (as an example, not limitation, the terminal 20 of the user A.A) and an example of payment management processing executed by the control unit 11 of the server 10 are shown. .
Note that the second half of the process can be executed in the same manner as in FIG. 5-12 as an example, not as a limitation, so detailed description will be omitted.

After executing steps A610 to A130, the control unit 21 of terminal A executes steps after A190.
After executing each step of S480 to S120, the control unit 11 of the server 10 receives the payment request information from the terminal A through the communication I/F 14, and executes steps after S500b.

In this modification, the terminal 20 integrates a first account that can be settled by the user of the terminal 20 itself and a user account of the user of the terminal 20 (not a limitation, but an example of a second account). Based on the account code reader information, the code reader screen for reading the payment store code (not limited but an example of the first code reader information) is displayed on the display unit 24 . Then, the terminal 20 has a configuration in which the control unit 21 executes processing related to payment based on the payment store code being read by the terminal 20 whose code reader screen based on the integrated account code reader information is displayed on the display unit 24. showing.

Also, based on the code information being read by the terminal on which the first code reader information is displayed, settlement can be easily realized.

<Seventh Modification (2)>
We used the account consolidation process to link multiple accounts to a single code, but that doesn't have to be the case. By way of example and not limitation, payments may be made by using multiple accounts in parallel.

FIG. 7-3 is a flowchart showing an example of the flow of processing executed by each device in this modified example. From the left side, an example of payment processing executed by the control unit 21 of the terminal A (as an example, not limitation, the terminal 20 of the user A.A) and an example of payment management processing executed by the control unit 11 of the server 10 are shown. .
Note that the second half of the process can be executed in the same manner as in FIG. 5-15 as an example, not as a limitation, so detailed description will be omitted.

First, as a non-limiting example, the control unit 21 of the terminal A sends information for selecting parallel use of the common wallet available from the terminal A and its own electronic money account to the server via the communication I/F 22. 10 (A620).
Information for choosing to parallelize accounts includes, by way of example and not limitation, a common wallet ID, user A. A's payment application ID.

Upon receiving information for selecting account parallel use from terminal A via communication I/F 14, control unit 11 of server 10 executes step S540 based on the information for selecting account parallel use. Then, the control unit 11 of the server 10 executes steps S550 to S120, and when payment request information is received from the shop code reader device 50, executes steps after S570.

When receiving the first parallel code information and the second parallel code information from the server 10 by the communication I / F 22, the control unit 21 of the terminal A executes each step of A510 to A130, and from the server 10 by the communication I / F 22 When the account parallel settlement result information is received, steps after A520 are executed.

As described above, the integrated account code information (not limited, but an example of the first code information) includes the payment application ID to be integrated (not limited, but an example of information about the second account) and the common wallet ID (example, not limitation, of information about common accounts) is said to include or be associated with.

In this modification, integrated account code information (not limited, but an example of first code information) includes second code information and third code information, and the second code information is a common wallet ID (not limited to , an example of a common account), the third code information is associated with a payment application ID to be integrated (an example of a second account, not limitation), and the second code information is different from the third code information It shows the configuration displayed in the area.
As an example of the effect obtained by such a configuration, settlement can be realized based on individual code information displayed in different areas.

<Seventh modification (3)>
In the seventh embodiment, a failure to pay with the integrated account that initially presented the code terminates the process, but that need not be the case.
As an example and not by way of limitation, if a payment fails on an integrated account, it may charge its own account, increase the balance of the integrated account to make up for the insufficient balance, and make another payment.

7-4 and 7-5 are flowcharts showing an example of the flow of processing executed by each device in this modified example. From the left side, the payment processing executed by the control unit 21 of the terminal A (as an example, not limitation, the terminal 20 of the user A.A), the payment management processing executed by the control unit 11 of the server 10, the store POS system (in the limitation As an example, an example of the store payment processing executed by the control unit 51 of the store code reader device 50, which is a component of the store POS system 40) of the member store S1, is shown.
Note that the second half of the process can be executed in the same manner as in FIG. 6B as an example, not as a limitation, so detailed description will be omitted.

The control unit 21 of terminal A executes steps A610 to A130. Then, the control unit 11 of the server 10 executes steps S480 to S120. The control unit 51 of the shop code reader device 50 executes the processes of P100-P110.

Control unit 11 of server 10 receives payment request information from store code reader device 50 via communication I/F 14 . In this case, the payment request information includes an integrated account payment token based on the integrated account code information sent in step S490a. Therefore, the control unit 11 of the server 10 executes integrated account settlement processing (S680). The integrated account settlement process can be executed in the same manner as the step of S500a in FIG. 5-7, so the detailed description is omitted.

If the settlement is successful in S680 (S690: YES), the control unit 11 of the server 10 advances the process to step S510 in FIG. 6-2.
If the settlement fails in S680 (S690: NO), the control unit 11 of the server 10 sends information indicating that the settlement has failed and insufficient settlement balance information including the amount of the settlement balance shortage in the integrated account in that case, It is transmitted to the terminal A and the store code reader device 50 through the communication I/F 14 (S700).

Here, the payment balance shortage information in this modified example is information indicating that the balance of the integrated account is insufficient. This account is integrated with A's user account. Therefore, the payment balance shortage information in this modification includes the common wallet balance and user A. This is information indicating that A's electronic money account balance is insufficient.

Then, the control unit 11 of the server 10 further executes steps S190 to S210, and upon receiving payment request information from the shop code reader device 50 via the communication I/F 14, executes steps from S500a.

When the communication I/F 22 receives the payment balance shortage information from the server 10 (A610: YES), the control section 21 of the terminal A executes steps A280 to A290. After executing steps A210 to A230, the control unit 21 of terminal A receives integrated account settlement result information from the server 10 via the communication I/F 22, and executes step A480.
If the payment balance shortage information is not received (A610: NO), the control unit 21 of terminal A receives the integrated account payment result information from the server 10 via the communication I/F 22, and executes steps after A480.

When receiving the payment balance shortage amount from the server 10 via the communication I/F 54 (P200: YES), the control section 51 of the shop code reader device 50 executes the steps from P130 onwards. If the payment balance shortage is not received (P200: NO), the control unit 51 of the store code reader device 50 receives payment result information from the server 10 via the communication I/F 54, and executes steps from P160 onwards.

In this modification, the terminal 20 stores the estimated payment amount (not limited, but an example of the amount of the first payment), the common wallet balance (not limited, but an example of the balance of the common account), and the terminal 20 user based on the balance of the electronic money account (an example of the balance of the second account, not limited), the balance of the common wallet balance and the balance of the electronic money account of the user of the terminal 20 itself is insufficient. Insufficient balance information (not a limitation, but an example of first information regarding insufficient balances of the common account and the second account) is displayed on the display unit 24 . Then, the terminal 20 performs a process of charging the electronic money account of the user of its own terminal 20 based on the input of the payment balance shortage information by the user of its own terminal 20 (not limited to, remittance to the second account example of processing) is executed by the control unit 21. FIG.
As an example of the effect obtained by such a configuration, it is possible to inform the user of the terminal that the balances of the common account and the second account are insufficient. Also, money can be transferred to the second account based on the input of the first information by the user of the terminal.

<Seventh modification (4)>
In the seventh embodiment and the seventh modification (3), even if the balance of the common wallet is insufficient at the time of payment using the integrated account and the balance of the user's electronic money account is used to pay for the advance, the amount to be paid for the payment is paid by using the balance of the user's electronic money account. (User BB as an example and not by way of limitation), but may or may not.

In this case, the flow in FIG. 6-7 should be executed in the second half of the process instead of the flow in FIG. 6-2.

<Seventh modification (5)>
In the seventh modification (3), if the payment with the integrated account fails, the account is charged to increase the balance of the integrated account to compensate for the lack of balance, but this need not be the case.
By way of example and not limitation, other common wallet members may be requested to transfer money to the common wallet to compensate for the insufficient balance.

FIG. 7-6 is a flow chart showing an example of the flow of processing executed by each device in this modified example. From left to right: payment processing executed by control unit 21 of terminal A (terminal 20 of user A.A as an example, not limitation), control of terminal B (terminal 20 of user B.B as an example, not limitation) payment cooperation processing executed by the unit 21, payment management processing executed by the control unit 11 of the server 10, and a store code reader device which is a component of the store POS system (as an example, not a limitation, the store POS system 40 of the member store S1) 50 respectively show an example of the store payment processing executed by the control unit 51 of the control unit 50. FIG.
Note that the first half of the process can be the same as in FIG. 7-4 as an example without limitation, and the second half of the process can be the same as in FIG. 6-2 as an example without limitation, so the description is omitted here. do.

After executing step A290, control unit 21 of terminal A executes steps A360 to A380, and upon receiving integrated account settlement result information from server 10 via communication I/F 22, executes steps after A480.
The control unit 21 of terminal B executes steps B140 to B170 and terminates the process.
After executing steps S340 to S390, the control unit 11 of the server 10 receives payment request information from the store code reader device 50 via the communication I/F 14, and executes steps after S500a.
Note that each step of the process can be executed in the same manner as in FIG. 4-19, so the detailed description is omitted.

6-9 and 4-21 are executed instead of the flow of FIG. 6-2 in the second half of the process, when the balance of another user's electronic money account is used to pay is the user A. of terminal A who paid the advance. It may or may not be billed to A.

In addition, when another common wallet member is requested to transfer money to the common wallet, but the transfer to the common wallet is not approved by the common wallet member, the integrated account code information is displayed on the terminal 20 that requested the transfer. 24, or processing for subsequent payments may not be executed.

<Seventh Modification (6)>
In the seventh modification (3), if the payment with the integrated account fails, the account is charged to increase the balance of the integrated account to compensate for the lack of balance, but this need not be the case.
By way of example and not limitation, a unified account consisting of a common wallet and its own electronic money account may additionally include electronic money accounts of other common wallet members.

7-7 and 7-8 are flowcharts showing an example of the flow of processing executed by each device in this modified example. From the left side, the payment processing executed by the control unit 21 of the terminal A (as an example, not limitation, the terminal 20 of the user A.A), the payment management processing executed by the control unit 11 of the server 10, the store POS system (in the limitation As an example, an example of the store payment processing executed by the control unit 51 of the store code reader device 50, which is a component of the store POS system 40) of the member store S1, is shown.
Note that the first half of the process can be the same as that in FIG. 7-4 as an example, not as a limitation, so the description is omitted here.

When the control unit 21 of terminal A executes step A290, a screen for selecting whether or not to further integrate another electronic money account (as an example, but not limited to, the electronic money account of user B.B) into the integrated account is displayed. , is displayed on the display unit 24 (A620). In the following, the addition of additional electronic money accounts to an integrated account is referred to as "account reintegration".

If reintegration of the accounts is selected based on the user operation on the input/output unit 23 of terminal A (A620: YES), the control unit 21 of terminal A receives the integrated account ID of the integration source and the user to be added. account reintegration request information including the payment application ID is transmitted to the server 10 via the communication I/F 22 .
If reintegration of the accounts is not selected based on the user operation on the input/output unit 23 of terminal A (A620: NO), the control unit 21 of terminal A receives the integrated account from the server 10 via the communication I/F 22. Receive settlement result information and execute step A480 in FIG. 6-2.

When account reintegration request information is received from terminal A via communication I/F 14 (S710: YES), control unit 11 of server 10 executes account reintegration processing (S720).
If the account reintegration request information is not received (S710: NO), the control unit 11 of the server 10 receives the payment request information from the store code reader device 50 via the communication I/F 14, and executes the steps after S500a. .

In the account reintegration process, the control unit 11 of the server 10 searches the integrated account management data record having the integrated account ID of the integration source from the integrated account management database 159, and assigns the user B. B's payment application ID is added and stored. The balance of the integrated account is the sum of the electronic money balance of the payment application ID added to the integrated account member ID.

Then, the control unit 11 of the server 10 transmits the reintegration account information including the electronic money balance of the reintegrated account to the terminal A via the communication I/F 14 (S730).

When receiving the reintegrated account information from the server 10 through the communication I/F 22, the control unit 21 of the terminal A updates and displays the electronic money balance of the reintegrated integrated account on the display unit 24 (A640). Then, the control section 11 of the shop code reader device 50 executes steps P140 to P160, and ends the process.

Note that, when executing the account reintegration process, the control unit 11 of the server 10 regenerates the integrated account payment token and the integrated account code information including the new integrated account payment token, and sends it to the terminal A via the communication I/F 14. You may send. In this case, when receiving the integrated account code information from the server 10 via the communication I/F 22, the control unit 21 of the terminal A updates the integrated account code information on the display unit 24 and causes the display unit 24 to display it.

Upon receiving the payment request information from the store code reader device 50 via the communication I/F 14, the control unit 11 of the server 10 executes reintegration account payment processing (S740).

In the integrated account settlement process, the control unit 11 of the server 10 retrieves the integrated account ID from the requested integrated account payment token. The control unit 11 of the server 10 further generates an integrated account member ID linked to the integrated account ID (here, the payment application ID of user A.A, the payment application ID of user B.B, and the common wallet ID of the common wallet). based on the user A. A's electronic money account balance and user B.A. Using the total amount of B's electronic money account balance and common wallet balance, a settlement process is executed to make payment of the planned settlement amount to the affiliated store specified by the store ID for the integrated account.

If the settlement with the integrated account succeeds, the control unit 11 of the server 10 reduces the common wallet balance by the expected settlement amount.
On the other hand, if the common wallet balance is less than the planned settlement amount, the control unit 11 of the server 10 preferentially uses the common wallet balance for payment, as an example and not as a limitation. (= scheduled settlement amount - common wallet balance) A's electronic money account balance and user B.A. The balance of B's electronic money account is split (divided evenly) and subtracted.

Next, the control unit 11 of the server 10, as an example and not a limitation, sends payment result information including the success or failure of the payment processing and the reintegrated integrated account balance after the payment processing to the store code reader device 50 via the communication I/F 14. (S750).

In addition, the control unit 11 of the server 10, as an example and not a limitation, determines the success or failure of the payment process, the electronic money account/common wallet balance of each user constituting the integrated account after the payment process, and the electronic money account/common wallet balance of each user. reintegration account settlement result information including the payment amount in the wallet is sent to terminal A via the communication I/F 14 (S760), and the process ends.

Upon receiving the reintegration account settlement result information from the server 10 via the communication I/F 22, the control unit 21 of terminal A causes the display unit 24 to display the reintegration account settlement result information (A650), and ends the process.

Note that in account reintegration, the electronic money account that can be added to the integrated account is not limited to the user account. You may or may not add another common wallet.

In this modification, settlement is performed by selecting the common wallet balance ( It shows a configuration in which payment is preferentially made from the common account balance (an example, not a limitation).
As an example of the effect obtained by such a configuration, since payment is preferentially made from the balance of the common account, other accounts can be used as additional accounts.

In addition, in this modification, the terminal 20 has a user account of the user of its own terminal 20 (an example of a second account, not a limitation) and the user accounts of other common wallet members. It shows a configuration in which the control unit 21 executes processing related to settlement based on an account and a common account.
As an example of the effect obtained by such a configuration, settlement can be realized based on the common account and each account of users who can settle using the common account, including the second account.

Also, this modified example shows a configuration in which the integrated account code information (not limited, but an example of the first code information) is associated with each user account of the common wallet members.
As an example of the effect obtained by such a configuration, it is possible to use the first code information associated with each account of a user who can make a payment using a common account for payment.

In addition, this modified example shows a configuration in which each user account of a common wallet member is deducted by splitting the balance of the common wallet by the shortfall (divided equally), and payment is made based on settlement.
As an example of the effect obtained by such a configuration, fair settlement can be realized because the shortfall in the balance of the common account is evenly allocated to each account of users who can settle using the common account.

<Seventh Modification (7)>
In the seventh modification (6), the account reintegration process that integrates the electronic money accounts of two or more users with the common wallet and the payment using the reintegrated account once attempted payment using the integrated account and failed Although it was decided to do it later, it is not limited to that.
By way of example and not limitation, reintegration of accounts may occur after FIG. 6-1.

<Seventh modification (8)>
When applying the user-provided code payment, the terminal 20 receives code information (payment code, etc.) associated with the user account of the user of the terminal 20 itself (not limited to, the third account associated with the second account). example of code information) is displayed on the display unit 24 . In addition, the terminal 20 displays, as a non-limiting example, information related to the common wallet (a common wallet ID, etc.) (not a limitation, but an example of common account information) on the same screen. Then, as a non-limiting example, the common account and the user account of the user of the terminal 20 of the terminal 20 are associated with each other based on the input by the user of the terminal 20 of the terminal 20 of the information about the shared wallet displayed by the terminal 20. The account code information (not limited, but an example of the first code information) may be displayed on the display unit 24, or may not be displayed.

Similarly, when applying store presentation type code payment, the terminal 20 displays a code reader screen for reading the payment store code based on the code reader information associated with the user account of the user of the terminal 20 itself (limited to (an example of a third code reader screen associated with the second account) is displayed on the display unit 24 . In addition, the terminal 20 displays information about the common wallet (common wallet ID, etc.) on the same screen as an example and not a limitation. Then, as a non-limiting example, the common account and the user account of the user of the terminal 20 of the terminal 20 are associated with each other based on the input by the user of the terminal 20 of the terminal 20 of the information about the shared wallet displayed by the terminal 20. A code reader screen for reading the payment store code based on the account code reader information (not limited, but an example of the first code reader screen) may be displayed on the display unit 24, or may not be displayed. good.

As an example of the effect obtained by such a configuration, the third code information or the third code reader information associated with the second account can be displayed on the display area of the terminal and used for payment. Also, first code information in which a first account that can be settled by the terminal user and a second account different from the first account are associated based on input by the terminal user to the common account information, or code information The first code reader information, which is a display related to reading, can be displayed on the display area of the terminal and used for payment.

In addition, in the above, when the user-presented code payment is applied, the terminal 20 replaces the code information (payment code, etc.) associated with the user account of the user of the terminal 20 itself, as an example and not as a limitation , the common wallet code information associated with the common account (one example, without limitation, of the third code information associated with the first account) may or may not be displayed.
In addition, in the above, when applying store presentation type code payment, the terminal 20 displays the code reader screen for reading the payment store code based on the code reader information associated with the user account of the user of the terminal 20 itself. Alternatively, by way of example and not limitation, to display a code reader screen for reading a payment merchant code (an example, but not a limitation, of third code information associated with a first account) based on common wallet code reader information. You may or may not.

As an example of the effect obtained by such a configuration, the third code information or the third code reader information associated with the first account can be displayed on the display area of the terminal and used for payment. Also, first code information in which a first account that can be settled by the terminal user and a second account different from the first account are associated based on input by the terminal user to the common account information, or code information The first code reader information, which is a display related to reading, can be displayed on the display area of the terminal and used for payment.

<Seventh Modification (9)>
In the seventh embodiment, similarly to the fourth modified example (9), payment can be made by wireless communication (including short-range wireless communication) instead of code payment.
This can be similarly realized by applying the processing described in the fourth modified example (9) to the account integration described in the seventh embodiment.

<Eighth embodiment>
The eighth embodiment is an embodiment related to billing/remittance of the above-described out-of-pocket amount. The billing and remittance of the payment amount can be applied to any of the above-described second to seventh embodiments.
In the eighth embodiment, the terminal 20 of the common wallet member uses the payment application to execute the payment at the member store from the electronic money balance of the common wallet. When the electronic money balance of the common wallet is insufficient at the time of payment, the insufficient balance of the common wallet is compensated by remittance from the user's electronic money account to the common wallet.
In addition, in the eighth embodiment, when the common wallet is discarded, the amount paid from the user's electronic money account balance is billed.

The content described in the eighth embodiment can be applied to each of the other embodiments and modifications.
Moreover, the same code|symbol is attached|subjected about the component same as an already-appearing component, and description for the second time is abbreviate|omitted.

"Discarding a common wallet" means terminating a common wallet, more specifically, by way of example and not limitation, deleting for no further use of the common wallet.
As a non-limiting example, common wallet destruction that deletes common wallet data stored and managed by the server 10 in response to a destruction request from the terminal 20 of the representative of the common wallet member or the terminals 20 of other common wallet members. Processing is performed.

The payment processing at the terminal of the common wallet member each time can be executed in the same way as shown in FIGS. detailed description is omitted.

<Data structure>
FIG. 8-1 is a diagram showing a data configuration example of a second common wallet management database 157B, which is an example of the common wallet management database 157 stored in the storage unit 15 of the server 10 in this embodiment.
Common wallet management data is stored in the second common wallet management database 157B as management data for each common wallet ID.

In each common wallet management data, for example and not limitation, a common wallet ID, a common wallet name, a common wallet balance, a common wallet member ID, and reimbursement history data are associated and stored.

The common wallet ID, common wallet name, common wallet balance, and common wallet member ID are the same as in the first common wallet management database 157A.

The advance payment history data is executed for this common wallet when a payment is made using this common wallet and part or all of the scheduled settlement amount is paid from the user's electronic money account balance due to insufficient balance of the common wallet. This is data for recording the history of reimbursement, and for example and not limitation, a reimbursement person ID, reimbursement person name, reimbursement date and time, and reimbursement amount are stored in association with each other.

The payer ID is an identifier for identifying the executor (payer payer) who uses his own electronic money account balance to pay for the lack of balance in the common wallet. The payment application ID of the user who makes the advance payment is stored.

The payer name is the name of the payer, and as an example and not as a limitation, the user name corresponding to the payer ID is stored.

The payment date and time is an item for recording the date and time when the payment is made on behalf of the customer. As an example and not as a limitation, the date and time when the control unit 11 of the server 10 executed step S170a in FIG. 4-5 is stored.

The payment amount is the amount paid from the user's electronic money account balance due to the lack of balance in the common wallet. remembered.

Assume that payment processing (first payment processing) is executed according to FIGS. As a non-limiting example, it is assumed that the settlement process failed in step S250a in FIG.

In step S170a of FIG. 4-5, when the payment process is successful, the control unit 11 of the server 10 selects the ID of the payment application currently executing the payment process ("U0001", which is the payment application ID of user A.A in this example). ), its user name ("A.A" in this example), the date and time when the payment process was executed ("2020/5/1/**:**:**" in this example), and Fig. 4- 4, the balance shortfall amount (=advance payment amount) ("1,000 yen" in this example) transmitted in step S270a of 4 is added in association with the payment history data.

Note that if the settlement balance shortage is "0" or if the settlement process fails in step S170a in FIG.

It is also assumed that terminal B executes another payment process (second payment process) in accordance with FIGS. 4-4 and 4-5. In this case, as an example and not as a limitation, assume that the balance shortfall is "3,000 yen", and user B. If the payment process is successful by transferring money from B's electronic money account to the common wallet, the control unit 11 of the server 10 receives the payment application ID that is executing the payment process (in this example, the payment application ID of user BB). "U0002"), its user name ("B.B" in this example), and the date and time when the payment process was executed ("2020/5/5/**:**:**" in this example) , and the payment balance shortfall amount (=advance payment amount) (“3,000 yen” in this example) are added in association with the payment history data.

When one of the terminals 20 of the common wallet members (as an example, but not limited to, terminal A of user A.A) selects to discard the common wallet, the control unit 21 of terminal A sends the common wallet destruction request information is transmitted to the server 10 via the communication I/F 22 .
Upon receiving common wallet discard request information from terminal A via communication I/F 14, control unit 11 of server 10 executes billing processing for the amount of payment for each amount of payment stored in the payment history data.

As an example and not a limitation, in the second common wallet management database 157B illustrated in FIG. **” is billed for “500 yen” (=1,000 yen/2 persons). Next, terminal A is billed for "1,500 yen" (=3,000 yen ÷ 2 people), which is the advance payment amount for "2020/5/5/**:**:**". .
Individual billing processes can be executed in the same manner as in FIGS. 4-9, for example and not by way of limitation, and therefore will not be described in detail.

As an example and not a limitation, when terminal A selects to discard the common wallet and selects not to charge its own out-of-pocket amount, the control unit 11 of the server 10 causes terminal B For example, information including the fact that the advance payment amount of "2020/5/1/**:**:**" will not be charged may be transmitted to prevent the billing process from being executed.

When billing processing for all out-of-pocket amounts stored in the out-of-pocket payment history data is executed, the control unit 11 of the server 10 executes common wallet destruction processing.

The payment processing executed by the terminal is not limited to the fourth embodiment, and can be applied to any of the second to seventh embodiments.
When the account integration process is involved, the amount paid by the user's electronic money account balance may be used as the payment amount.

<Effects of the eighth embodiment>
In the eighth embodiment, the payment advance amount request information is transmitted to the second terminal 20 (the terminal 20 that receives the request) based on the destruction of the common wallet (not a limitation, but an example of the destruction of the common account). is shown.
As an example of the effect obtained by such a configuration, billing information based on payment can be transmitted to the terminal based on the cancellation of the common account.

Further, in the eighth embodiment, the above-mentioned advance payment amount billing information is payment advance amount billing information for the user of the second terminal 20 (not a limitation, but an example of first billing information). Based on the user account (not limited but an example of a second account) of the user of the second terminal 20 (invoicing terminal 20), processing related to payment (not limited but an example of processing related to the second payment) is executed. , billing information for the user of the first terminal 20 based on the settlement by the user of the second terminal 20 (an example of the second settlement, not limiting) 2 billing information example) shows the configuration sent to the first terminal 20 (an example of the first terminal, not limitation) based on the destruction of the common wallet.
As an example of the effect obtained by such a configuration, second billing information different from the first billing information based on the second payment is transmitted to the first terminal based on the cancellation of the common account. can be done.

In addition, in the present embodiment, the terminal 20 sends information (not limited to, but an example of information about changing the billing information) including the fact that no reimbursement is requested to at least one of the terminals 20 of the common wallet member. The configuration for transmission by the communication I/F 22 is shown.
As an example of the effect obtained by such a configuration, a change in billing information is notified by transmitting information regarding the change in billing information to at least one of the terminals of the user that can settle accounts using a common account. can be done.

<Eighth modification (1)>
In the eighth embodiment, when the common wallet is discarded, the common wallet is used to bill the amount of the advance paid up to that point, but the present invention is not limited to this.

In this modification, the terminal 20 of the common wallet member uses the payment application to make payment at the member store from the electronic money balance of the common wallet or the electronic money of the integrated account of the common wallet and the user's electronic money account. Run from your balance. Then, when performing the common wallet destruction operation, the common wallet balance is distributed to the user accounts and remitted (refunded) based on the remittance amount from the user account to the common wallet and the advance amount paid by the user account.
Hereinafter, remittance from the user account to the common wallet is referred to as "contribution to the common wallet", and the remittance amount is referred to as "contribution amount".

The payment processing at the terminal of the common wallet member each time can be executed in the same way as shown in FIGS. Therefore, detailed description is omitted here.

FIG. 8-2 is a diagram showing a data configuration example of a third common wallet management database 157C, which is an example of the common wallet management database 157, stored in the storage unit 15 of the server 10. As shown in FIG.
Common wallet management data is stored in the third common wallet management database 157C as management data for each common wallet ID.

Each common wallet management data includes, as a non-limiting example, a common wallet ID, a common wallet name, a common wallet balance, a common wallet member ID, a common wallet creation date and time, investment history data, and payment history data. are stored in association with each other.

The common wallet ID, common wallet name, common wallet balance, and common wallet member ID are the same as in the first common wallet management database 157A.

The common wallet creation date and time stores the date and time when the common wallet was created.

The investment history data is history data of investments executed for this common wallet, and as an example and not limitation, the investor ID, investor name, investment date and time, and investment amount are stored in association with each other. .

The investor ID is an identifier for identifying a performer (investor) who makes a contribution to this common wallet, and as an example and not a limitation, the payment application ID of the user who makes the contribution is stored.
The investor name is the name of the investor, and as an example and not limitation, the user name corresponding to the investor ID is stored.
The investment date and time is the date and time when the investment is made, and as an example, not as a limitation, the date and time when the investor made the investment in the common wallet is stored.
The investment amount is the investment amount per investment in this common wallet executed by the investor.

In FIG. 8-2, by way of example and not limitation, for the common wallet "camp funds", user A. A puts "3,000 yen" to "2020/3/11/**:**:**" and "3,000 yen" to "2020/4/14/**:**:**" is shown to have invested in Also, by way of example and not limitation, user B. B puts "3,000 yen" to "2020/3/12/**:**:**" and "3,000 yen" to "2020/4/14/**:**:**" is shown to have invested in

The payment history data is the history data of payments executed and completed using this common wallet. It is stored in association with a collection flag.

The payer ID is an identifier for identifying the executor (payer) who executes the payment using this common wallet at the affiliated store, and as an example, without limitation, the payment application ID of the user who makes the payment is stored. be done.
The store name is a name for identifying the member store where payment is made, and as an example, not a limitation, stores the name of the store or service that the member store registers when registering for use of the payment application.
The payment date and time is the date and time when the payer executes the payment using the payment application at the member store of the store name. The date and time of success are stored.
The amount to be paid is the scheduled payment amount to be paid by the payment application at the affiliated store of that store name. A scheduled settlement amount based on the received settlement request information is stored.
The advance amount is the amount paid from the user's electronic money account balance due to the lack of the common wallet balance when the payment is made from the electronic money balance of the account integrated with the common wallet and the user's electronic money account, and is not limited. As an example, the amount paid from the payer's electronic money account based on the results of the integrated account settlement process is stored. If the integrated account settlement process is not executed, the advance amount is set to "0".

The recovery flag is flag information for recording whether or not the payment amount is billed for each payment when the payment amount is greater than "0", and whether or not settlement is completed. The control unit 11 of the server 10 executes the settlement and remittance processing, and when it succeeds, "completed" is stored as an example and not as a limitation. If the control unit 11 of the server 10 does not execute the settlement remittance process or the settlement request process fails, "not yet" is stored as an example and not as a limitation. Also, when the amount paid is "0", there is no need to execute settlement, so "-" is stored as an example rather than as a limitation.
The billing process for the out-of-pocket amount for each payment can be executed in the same manner as in FIG. 6-7, not as a limitation, but as an example, so detailed description will be omitted.

By way of example and not limitation, in FIG. 8-2, the payment history data shows that payer "U0001" (i.e., user A.A.) uses the common wallet "Camp Funds" to pay "2020/4/5/* *:**:**” indicates that a payment of “5,000 yen” was made at the store “EE Super”. In addition, the payer "U0001" (that is, user A.A) made a payment of "3,000 yen" at "2020/4/11/**:**:**" at the store "AA Sports". and user A. It shows that "2,000 yen" has been advanced in A's electronic money account, and that the payment for the advance has not yet been completed.

As a non-limiting example, when the common wallet destruction request information is received from the terminal A via the communication I/F 14, the control unit 11 of the server 10, based on the common wallet management data of the third common wallet management database 157C, Execute wallet settlement discard processing.

In the common wallet settlement and discarding process, first, the total investment amount for each investor is calculated for each investor ID in the investment history data. Next, for each payer ID in the payment history data, the total out-of-pocket amount for each payer is calculated. In addition, in the calculation of the total amount paid, only the amounts paid with the recovery flag set to "unfinished" are included.

By way of example and not limitation, in FIG. A's total investment amount is "6,000 yen" (=3,000 yen +3,000 yen), and user B. The total investment amount of B is "6,000 yen" (=3,000 yen + 3,000 yen). Also, user A. A's total advance amount is "2,000 yen", and user B. The total advance amount for B is "6,000 yen".

Next, the sum of the total amount invested by all common wallet members and the total amount paid is calculated as the total amount invested in the common wallet "camping funds". As an example and not a limitation, in FIG. 8-2, the total investment amount is "20,000 yen" (=6,000 yen+6,000 yen+2,000 yen+6,000 yen).

After that, the average payment amount per common wallet member spent from the common wallet at the time of executing the common wallet settlement and destruction process is calculated by "(total investment amount - common wallet balance) ÷ number of common wallet members".
By way of example and not limitation, in FIG. 8-2, the average payment amount is "(20,000 yen-6,000 yen)/2=7,000 yen".

Next, for each payment application ID stored in the common wallet member ID, a scheduled refund amount for refunding the common wallet balance based on the ratio of the contribution amount is calculated. The scheduled refund amount is calculated by "(total investment amount + total advance amount) - average payment amount".
The scheduled refund amount is calculated from the sum of the amount directly invested in the common wallet by each user (total investment amount) and the amount indirectly invested in the common wallet (total advance amount). It will be the amount obtained by subtracting the amount obtained by dividing the payment amount evenly.
By way of example and not limitation, in FIG. The scheduled refund amount to user B is "6,000 yen + 2,000 yen - 7,000 yen = 1,000 yen". The scheduled refund amount to B is "6,000 yen + 6,000 yen - 7,000 yen = 5,000 yen".

Finally, the control unit 11 of the server 10 executes a refund process of transferring the scheduled refund amount using the common wallet balance to each electronic money account of the common wallet member.
If the scheduled refund amount is negative, the absolute value of the scheduled refund amount is used as the remittance amount, and settlement is performed by remittance from the user's electronic money account to the common wallet.

When the common wallet settlement discarding process is executed and the common wallet balance becomes "0", the control unit 11 of the server 10 executes the common wallet discarding process.

The payment processing executed by the terminal is not limited to the sixth embodiment, and can be applied to any of the second to seventh embodiments.
When executing the remittance process to the common wallet, it is sufficient to store the amount of insufficient settlement balance, which is the amount that at least needs to be remitted to the common wallet in order to complete the payment in the common wallet, as the advance amount. .
