[0009] Hereinafter, with reference to the drawings, an information providing device, a system, an information providing method, and a program according to the present invention will be described in detail. The information providing device creates an invoice that satisfies invoice requirements and is issued by an affiliated store that uses an electronic payment service as a provider of goods or services to a user who is a purchaser in the electronic payment service. The electronic payment service is provided by cooperation between an application program and a payment server. In the following description, the application program is referred to as a payment application. The electronic payment service is a service that supports payments related to the purchase of goods or services at a store. The store is, for example, a physical store (real store) that exists in the real world, but may also include a virtual store for electronic commerce. The virtual store may include a store provided by an entity different from the operator of the electronic payment service. In that case, when making a payment for shopping at the virtual store, the screen is controlled to transition to an interface screen of the electronic payment service. In the electronic payment service, the store is treated as belonging to, for example, an affiliated store (brand), and processing such as payment when a purchase is made at the store is mainly performed between the user and the affiliated store. Hereinafter, the electronic payment service provided to the user side will be described first, and then the interface for the affiliated store will be described.

[0010] [Electronic payment service] Fig. 1 is a diagram showing an example of a configuration for realizing an electronic payment service. The electronic payment service is realized mainly by a payment server 100. The payment server 100 communicates with, for example, one or more user terminal devices 10, one or more first store terminal devices 50, one or more second store terminal devices 70, and one or more employee terminal devices 80 via a network NW. The network NW includes, for example, the Internet, a LAN (Local Area Network), a wireless base station, a provider device, and the like.

[0011] The user terminal device 10 is, for example, a portable terminal device such as a smartphone or a tablet terminal. The user terminal device 10 is a computer device having at least an optical reading function, a communication function, a display function, an input reception function, and a program execution function. In the following description, components for realizing these functions are referred to as a camera, a communication device, a touch panel, a CPU (Central Processing Unit), etc. In the user terminal device 10, a processor such as a CPU executes a payment application 20, thereby operating to provide an electronic payment service to a user in cooperation with a payment server 100. The payment application 20 is installed in the user terminal device 10 from, for example, an application store, and controls the camera, communication device, touch panel, etc.

[0012] The first store terminal device 50 is installed, for example, in a store. The first store terminal device 50 is a computer device having at least a product price acquisition function, an optical reading function, a program execution function, and a communication function. The first store terminal device 50 includes a so-called POS (Point of Sale) device, and the product price acquisition function and the optical reading function may be realized by the POS device. The store code image 60 is placed in the store, and is a code image such as a QR code (registered trademark) printed on a paper or plastic medium. The store code image 60 may be displayed on a display placed in the store (which may be the display of a terminal device such as a smartphone).

[0013] The second store terminal device 70 is used by the operator of the affiliated store. The second store terminal device 70 is a smartphone, a tablet terminal, a personal computer, or the like. An interface 72 for affiliated stores runs on the second store terminal device 70. The interface 72 for affiliated stores may be an application for affiliated stores or a browser. The interface 72 for affiliated stores accepts coupon settings and the like by the operator of the affiliated store and transmits them to the payment server 100. The second store terminal device 70, which is a smartphone, has a function of displaying a code image corresponding to a store code image and reading a code image displayed by the user terminal device 10 by executing an application for affiliated stores. Some of the second store terminal devices 70 have a function similar to that of the first store terminal device 50, that is, a function of reading a code image using a camera and transmitting payment information to the payment server 100. This will be described later. This function is called a direct payment function.

[0014] The payment server 100 realizes electronic payment based on payment information received from the user terminal device 10 or the first store terminal device 50. The first store terminal device 50 may include a POS device and an affiliated store server, in which case the payment information is sent from the POS device via the affiliated store server to the payment server 100. In the following explanation, no distinction is made between these two and it is assumed that the payment information is sent from the first store terminal device 50.

[0015] 2 and 3 are sequence diagrams illustrating the general flow of electronic payment. There may be two patterns of electronic payment: pattern 1 and pattern 2.

[0016] In the case of pattern 1 (hereinafter referred to as user scan) shown in FIG. 2, the user terminal device 10 with the payment application 20 activated decodes the store code image 60 by the optical reading function (S1). The store code image 60 includes store URL (Uniform Resource Locator) information. This store URL is an electronic payment service domain to which store-identifying information is added, and is associated with an affiliated store ID, a store ID, etc. in the payment server 100 (described later). The payment application 20 transmits the first payment information including the store URL and the account ID to the payment server 100 (S2). The payment server 100 searches for store information (described later) from the affiliated store ID and the store ID corresponding to the store URL, acquires the affiliated store name and the store name information (S3), and transmits it to the payment application 20 (S4). The user inputs the payment amount into the user terminal device 10 on the screen on which the affiliated store name and the store name are displayed (S5). Then, the user terminal device 10 generates second payment information including at least the payment amount, and transmits it to the payment server 100 (S6). The payment server 100 performs electronic payment based on the received second payment information (S7). The payment server 100 then transmits a payment completion notice (information for displaying a payment completion screen) to the payment application 20 (S8), and the payment application 20 displays the payment completion screen (S9). Note that when the store code image 60 is displayed on a display installed in the store, the store code image 60 may include not only the store URL but also information on the payment amount. In this case, the step of the user inputting the payment amount is omitted, and the information on the payment amount is included in the first payment information and transmitted to the payment server 100. Information on the affiliated store name and the store name may be included in the payment completion screen and displayed.

[0017] In the case of pattern 2 (hereinafter referred to as store scan) shown in FIG. 3, when the payment application 20 is started, when a payment operation is performed in the payment application 20, when an automatic update timing (e.g., every minute) occurs, and at other timings, the payment application 20 transmits a request for issuing a one-time code to the payment server 100 (S11). The payment server 100 generates a one-time code (S12) and transmits it to the payment application 20 (S13). The payment application 20 displays a code image such as a QR code or a barcode generated based on the one-time code (S14). The user holds (presents) the display surface of the user terminal device 10 over the first store terminal device 50, and the first store terminal device 50 decodes the code image by an optical reading function and obtains the one-time code, etc. (S15). The first store terminal device 50 then generates payment information including the one-time code, payment amount, affiliated store ID, store ID, etc., and transmits it to the payment server 100 via the POS gateway device as described later (S16). The payment amount information is acquired in advance by reading a barcode or manually entering it. The payment server 100 identifies the user corresponding to the one-time code based on the received information and performs electronic payment (S17). The payment server 100 then transmits a payment completion notice to the payment application 20 (S18), and the payment application 20 displays a payment completion screen (S19).

[0018] Note that electronic payment may be performed using only one of the above patterns. Furthermore, the "account ID" described in FIG. 2 may be other information (e.g., a phone number) that can be used as user identification information. Furthermore, issuance of a one-time code may be omitted in the store scan, and the payment application 20 may display a code image generated based on the user's account ID. In this case, the payment server 100 identifies the user corresponding to the account ID instead of identifying the user corresponding to the one-time code.

[0019] [Payment server] FIG. 4 is a configuration diagram of the payment server 100 according to the first embodiment. The payment server 100 includes, for example, a communication unit 110, a payment content providing unit 120, a payment processing unit 130, an information management unit 140, a content providing unit for affiliated stores 150, and a storage unit 170. The content providing unit for affiliated stores 150 includes an acquisition unit 152 and a processing unit 154. The components other than the communication unit 110 and the storage unit 170 are realized, for example, by a hardware processor such as a CPU executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by cooperation between software and hardware. The program may be stored in advance in a storage device (a storage device with a non-transient storage medium) such as an HDD (Hard Disk Drive) or flash memory, or may be stored in a removable storage medium (non-transient storage medium) such as a DVD or CD-ROM, and installed in the storage device by inserting the storage medium into a drive device.

[0020] The storage unit 170 is a HDD, a flash memory, a RAM (Random Access Memory), etc. The storage unit 170 may be a NAS (Network Attached Storage) device that the payment server 100 can access via a network. The storage unit 170 stores information such as user information 172, payment content information 174, affiliated store / shop information 176, and payment details information 178 for each affiliated store.

[0021] The communication unit 110 is a communication interface for connecting to the network NW. The communication unit 110 is, for example, a network interface card.

[0022] The payment content providing unit 120 has, for example, a function of a Web server, and provides information (content) for displaying various screens of the electronic payment service to the user terminal device 10. The payment content providing unit 120 appropriately reads necessary content from the payment content information 174 and provides it to the user terminal device 10. The user terminal device 10 accepts various inputs by the user while the content is being played by the payment application 20, and transmits the above-mentioned payment information and the like to the payment server 100.

[0023] The payment processing unit 130 performs payment processing based on the payment information transmitted by the user terminal device 10 or the first store terminal device 50. The payment processing unit 130 performs payment processing while referring to the user information 172.

[0024] FIG. 5 is a diagram showing an example of the contents of the user information 172. The user information 172 is an example of the registration information of a user. The user information 172 is associated with information such as a user URL, an account ID, a corporate / individual business owner flag, a telephone number, a password, an email address, a user ID, a name or a name, an address, a date of birth, a registration date, a charge balance, a deferred payment setting, a deferred payment limit, a deferred payment usage amount, a deferred payment available amount, a payment method setting, a bank account, a credit card number, charge history information, and payment history information. The corporate / individual business owner flag is a flag indicating whether the user is a corporate or individual business owner, and is set to 1 if the user is a corporate or individual business owner, and is set to zero if the user is not a corporate or individual business owner. The user URL is used for remittance processing between users. When registering for a new electronic payment service, it is necessary to register a telephone number and a password. The account ID is issued to the user by the payment server 100, and the user ID is an ID that the user can set at will (or does not have to set). Similarly, email address, name, address, and date of birth are also information that the user can set at will (but do not have to set). The registration date is the date on which the user registered with the electronic payment service (the date on which the account was created). Hereinafter, the user's instance (electronic payment account) to which this information is associated will be referred to as the account.

[0025] The charge balance is information indicating the balance of electronic money that is set by a user by transferring money to an account in advance. Methods of transfer include transfer from an ATM (Automatic Teller Machine) of a designated business (bank) and transfer from a registered bank account. The deferred payment setting is information indicating whether or not the setting for enabling deferred electronic payment has been completed, and is set to either "completed" or "not completed." The payment method setting is setting information indicating whether the user will make electronic payment from the charge balance or deferred payment at that time. The bank account and credit card number are information on a bank account or credit card number (account number, card number) that can be deposited into an electronic payment service. The charge history information is a history of the user transferring money to an electronic payment service in advance to increase the charge balance. The payment history information is information indicating the details of the payment made by the user (date and time, store ID of the store where the purchase was made, payment amount, payment method, etc.) for each payment.

[0026] 6 is a diagram showing an example of the contents of affiliated store / store information 176. The affiliated store / store information 176 includes, for example, a first table 176A in which an affiliated store ID and a store ID are associated with a store URL, a second table 176B in which an affiliated store name and sales amount (described above) are associated with an affiliated store ID, and a third table 176C in which a store ID is associated with a store name. In addition to this information, the affiliated store / store information 176 may also include information such as the category of the affiliated store or store, the location of the store, and payment patterns.

[0027] The information management unit 140 manages user information 172 and affiliated store / store information 176 based on information acquired from the user terminal device 10 and the second store terminal device 70. The information management unit 140 adds new records to, edits, and deletes the user information 172 and affiliated store / store information 176.

[0028] [Electronic payment] When payment information is acquired from the user terminal device 10 or the first store terminal device 50, the payment processing unit 130 refers to the user information 172 to acquire the "payment method setting" of the user. For a user whose "payment method setting" is set to "charge balance", the payment processing unit 130 performs electronic payment as follows. For example, the payment processing unit 130 performs electronic payment by decreasing the charge balance managed in association with the user ID and increasing the item value of the affiliated store's sales. The item value of the affiliated store's sales is not used as electronic money itself, for example, and an amount corresponding to the item value of the sales is transferred to a bank account in a cycle according to an agreement between the affiliated store and the electronic payment service.

[0029] The payment processing unit 130 performs electronic payment for users whose "setting information" is set to "deferred payment" as follows. Deferred payment is set separately from "credit payment" in cooperation with a credit card company, which is a separate entity from the operator of the electronic payment service, and the operator of the electronic payment service acts as a creditor and allows electronic payment that is not dependent on the charge balance within the deferred payment limit. In order to receive the deferred payment service, a credit card provided by the operator of the electronic payment service may be required. The amount used for deferred payment is settled on the payment date of the following month, for example, by debiting from a bank account, for one month. In this case, the payment processing unit 130 performs provisional payment by adding the payment amount to the deferred payment amount and subtracting the same amount from the available deferred payment amount, and when the closing date comes, it performs processing to debit the payment for the current month on the payment date of the following month as described above, or requests the operator of the credit card company to perform such processing. In addition, if the payment amount exceeds the available deferred payment amount at the time of provisional payment, an error notification is returned to the payment application 20.

[0030] [Services for affiliated stores] The following describes the service for affiliated stores. In this specification, the service for affiliated stores is a service that creates qualified invoices issued by affiliated stores to users (corporate accounts or sole proprietors). An example of an information providing device is the one including the affiliated store content providing unit 150 and the affiliated store-specific payment details information 178 in FIG. 4. In FIG. 4, the information providing device is a function of the payment server 100, but the information providing device may be a device separate from the payment server 100.

[0031] The affiliated store content provider 150, for example, acquires a request for issuance of a qualified invoice that meets the invoice requirements from the affiliated store via the affiliated store interface 72. The request for issuance of a qualified invoice includes the user ID of the target user, the target period, etc. Hereinafter, the request form receives a request for issuance of a qualified invoice from the target user and sends the issuance request to the payment server 100.

[0032] The acquisition unit 152 acquires payment information corresponding to the issuance request (hereinafter, referred to as "payment information for invoice creation" to distinguish it from the payment information described in Fig. 2 and Fig. 3) at a request to a payment intermediary device that mediates payments in electronic payment services. The payment information for invoice creation includes, for example, the amount excluding tax, items, tax rate, points, etc. for each payment.

[0033] 7 is a diagram showing an example of a configuration including a payment intermediary device. The payment intermediary device includes, for example, some or all of an electronic commerce server 200, a POS gateway device 300, and a second store terminal device 70A.

[0034] The electronic commerce server 200 is a transaction management device of an electronic commerce business operator that uses an electronic payment service (in cooperation with an electronic payment service) to make payments. The electronic commerce server 200 provides users with electronic commerce services via the network NW. In the electronic commerce service, when the product or service to be purchased (put into the cart) is finalized and an electronic payment service is selected when selecting the payment method, the payment process is taken over by the payment server 100 and the electronic payment is completed. The electronic commerce server 200 holds the information required as payment information for creating an invoice, and can transmit this to the payment server 100 as necessary.

[0035] The POS gateway device 300 is a device that aggregates information from multiple POS devices included in each of the multiple first store terminal devices 50 and transfers it to the payment server 100. The POS devices do not communicate with the payment server 100 independently, but transmit payment information to the payment server 100 via the POS gateway device 300. The POS gateway device 300 also holds information required as payment information for creating an invoice, and can transmit this to the payment server 100 as necessary.

[0036] As described above, the second store terminal device 70A is one of the second store terminal devices 70 that has a direct payment function similar to that of the first store terminal device 50. The second store terminal device 70A is realized, for example, by using a tablet terminal with a camera. The second store terminal device 70A is equipped with a direct payment function as one function of the interface 72 for affiliated stores. The second store terminal device 70A also holds information required as payment information for creating an invoice, and can transmit this information to the payment server 100 as necessary.

[0037] The various payment intermediary devices described above may automatically transmit payment information for invoice creation to the payment server 100 each time an electronic payment is made, rather than transmitting payment information for invoice creation to the payment server 100 in response to a request from the payment server 100.

[0038] When the acquisition unit 152 acquires the payment information for invoice creation, it registers it in the payment details information for each affiliated store 178. Figure 8 is a diagram showing an example of the content of the payment details information for each affiliated store 178. The payment details information for each affiliated store 178, for example, associates the corporate number and registration number of the affiliated store with the affiliated store ID, and further associates information such as a payment ID that can identify the payment, the date (or date and time) of the payment, the payment amount (amount excluding tax), items, tax rate, points, etc., for each account ID (see Figure 5) of the user who made the payment with the affiliated store.

[0039] The corporate number of the affiliated store is obtained from the affiliated store when subscribing to the electronic payment service. Regarding the registration number, the acquisition unit 152 acquires the corporate number from the National Tax Agency server 400 by inputting the corporate number into an API (Application Programming Interface) provided by the National Tax Agency server 400.

[0040] When the processing unit 154 receives a request to issue a qualified invoice from an affiliated store, it references the payment details information for each affiliated store 178 and creates a qualified invoice that meets the invoice requirements to be issued by the affiliated store to the user. The invoice requirements must include the name or title and registration number of the business issuing the invoice (the affiliated store in this invention), the transaction date, transaction details, the total amount of the price excluding or including tax for each tax rate and the tax rate, the amount of consumption tax broken down by tax rate (rounding must be done for each invoice), and the name or title of the business receiving the document (user).

[0041] At this time, the processing unit 154, for example, refers to the user information 172, extracts users who have made payments with the affiliated store and whose corporate / individual business owner flag is set to 1, and automatically creates qualified invoices for all extracted users. Alternatively, if the request to issue a qualified invoice contains information specifying the target users, the processing unit 154 may create qualified invoices only for the specified users.

[0042] FIG. 9 is a diagram showing an example of a qualified invoice. The qualified invoice (shown in the figure as a "payment notice") includes the user's name, the affiliated store's name, and the affiliated store's registration number. In addition, the payment amount (excluding tax) for each tax rate transcribed from the affiliated store's payment details information 178 is listed, and the total amount of consumption tax for each tax rate is listed. The processing unit 154 sends the qualified invoice to the user's email address or displays it in a downloadable form within the payment application 20.

[0043] By carrying out this process, affiliated stores that use electronic payment services can reduce the effort of issuing qualified invoices for each user, allowing them to allocate human resources to necessary business. In addition, there is no need to carry out the process of obtaining the registration number required for qualified invoices, further reducing the business burden on affiliated stores. In this way, according to the embodiment, invoice support can improve service to affiliated stores.

[0044] According to the embodiment described above, it is possible to provide suitable invoice handling for affiliated stores that use electronic payment as providers of goods or services.

[0045] The above describes the form for carrying out the present invention using an embodiment, but the present invention is not limited to such an embodiment, and various modifications and substitutions can be made within the scope that does not deviate from the gist of the present invention.
