Description

[Technical Field]

[0001] The present invention relates to an information processing device, an information processing method, and a program. [Background technology]

[0002] BACKGROUND ART A system is known that notifies a user of usage information by email when a credit card is used (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-213491 Summary of the Invention [Problem to be solved by the invention]

[0004] It is common for vouchers to be exchanged to be standardized and exchanged electronically, but when users of such services receive vouchers by email when using a credit card, as with the technology described in Patent Document 1, data conversion is required when processing the vouchers received by email, which creates a problem of being more time-consuming than receiving vouchers in a standardized format.

[0005] The present invention has been made in consideration of these points, and aims to enable evidence data when a credit card is used to be processed in the same way as other evidence data, thereby simplifying the processing after the evidence data is received. [Means for solving the problem]

[0006] The information processing device of the first aspect of the present invention has a memory unit that stores user information that associates a registered card number, which is a card number for identifying a credit card, with user identification information, which is information for identifying the recipient user corresponding to the registered card number in an invoice network, which is a network for exchanging transaction data; an acquisition unit that acquires payment data indicating that a payment has been made by credit card, which includes at least a payment card number, which is the card number of the credit card used for the payment, from a terminal used at the affiliated store where the payment has been made with the credit card; an identification unit that identifies the user identification information corresponding to the payment card number in the user information; and a transmission unit that, when the user identification information corresponding to the payment card number is identified, transmits supporting data indicating that the transaction indicated by the payment data has been made to the user corresponding to the identified user identification information via the invoice network.

[0007] In the user information, each registered card number is further associated with a user destination indicated by the registered card number in a payment data transmission means different from the invoice network, and if user identification information corresponding to the payment card number is not identified, the transmission unit may transmit the supporting document data via the transmission means to the destination corresponding to the payment card number in the user information.

[0008] The system further includes a judgment unit that judges whether the supporting document data can be transmitted over the invoice network, and the user information further associates, for each registered card number, the destination of the user indicated by the registered card number in a supporting document data transmission means that is different from the invoice network, and if the judgment unit judges that the supporting document data cannot be transmitted over the invoice network, the transmission unit may transmit the supporting document data to the destination corresponding to the payment card number using the transmission means.

[0009] The user information may further be associated with registered member store identification information, which is identification information for identifying the member store that accepts credit card use, for each registered card number, and the payment data may further include payment member store identification information, which is identification information for identifying the member store where the credit card payment was made, and the identification unit may identify the user identification information in the user information that corresponds to the payment card number and payment member store identification information.

[0010] The acquisition unit acquires the method of transmitting supporting data selected by the credit card user when payment is made by credit card, in association with the payment data, and the transmission unit may transmit the supporting data via the invoice network to the user corresponding to the identified user identification information if (1) the transmission method associated with the acquired payment data indicates transmission via the invoice network, and (2) user identification information corresponding to the payment card number is identified.

[0011] An information processing method of a second aspect of the present invention includes the steps of: executing a computer; acquiring payment data from a terminal used at the affiliated store where the payment was made, the payment data including at least a payment card number, which is the card number of the credit card used for the payment, and indicating that the payment was made using the credit card; referencing user information stored in a memory unit that associates a registered card number, which is a card number for identifying a credit card, with user identification information, which is information for identifying the destination user corresponding to the payment card number in an invoice network, which is a network for exchanging transaction data, and identifying the user identification information corresponding to the payment card number in the user information; and, when the user identification information corresponding to the payment card number is identified, sending supporting data indicating that the transaction indicated by the payment data was made to the user corresponding to the identified user identification information via the invoice network.

[0012] In a third aspect of the program of the present invention, a computer is caused to execute the following steps: acquiring payment data from a terminal used at the affiliated store where the payment was made, the payment data including at least a payment card number, which is the card number of the credit card used for the payment, and indicating that the payment was made using the credit card; referencing user information stored in a memory unit that associates a registered card number, which is a card number for identifying a credit card, with user identification information, which is information for identifying the destination user corresponding to the payment card number in an invoice network, which is a network for exchanging transaction data, and identifying the user identification information corresponding to the payment card number in the user information; and, when the user identification information corresponding to the payment card number is identified, sending supporting data indicating that the transaction indicated by the payment data was made to the user corresponding to the identified user identification information via the invoice network. [Effects of the Invention]

[0013] According to the present invention, it is possible to process evidence data when a credit card is used in the same manner as other evidence data. [Brief explanation of the drawings]

[Figure 2] 1 is a block diagram showing a configuration of an information processing device 1. FIG. [Figure 3] 3 is a diagram showing an example of a data structure of user information stored in a storage unit 12. FIG. [Figure 4] 3 is a diagram showing an example of a data structure of user information stored in a storage unit 12. FIG. [Figure 5] 3 is a flowchart showing a processing flow in the information processing device 1. DETAILED DESCRIPTION OF THE INVENTION

[0015] [Outline of Information Processing System S] 1 is a diagram illustrating an overview of an information processing system S according to an embodiment. The information processing system S is a system for performing payments using a credit card and notifying a computer that performs accounting processing of supporting data indicating that a transaction has been made. The credit card is a credit card that is approved for use in purchasing products that are expenses of an organization such as a company, and is, for example, a corporate credit card.

[0016] The information processing system S has an information processing device 1, a store terminal 2, and an accounting processing device 3. The information processing device 1 and the accounting processing device 3 are communicatively connected via an invoice network N. The invoice network N is a network for sending and receiving transaction data. The invoice network N is, for example, Peppol (Pan European Public Procurement Online).

[0017] The information processing device 1 processes payments and notifies the accounting processing device 3 that made the payment of supporting data showing the transaction results. The information processing device 1 may also include the functions of the accounting processing device 3.

[0018] The store terminal 2 is a terminal used in a store and accepts payments. The store terminal 2 is, for example, a Point of Sale (POS) cash register. The store terminal 2 reads a credit card presented by a user U in the store and transmits payment data indicating the details of the payment to the information processing device 1.

[0019] The accounting processing device 3 is a device that manages the accounting of the organization to which user U belongs. The accounting processing device 3 acquires documents related to transactions via the invoice network N, performs accounting processing for the acquired documents, and issues transaction documents. The accounting processing device 3 is assigned a user ID issued for the organization whose accounting it manages. The user ID is an ID used to identify a user in the invoice network N (for example, the organization to which user U belongs). One example of the user ID is a Peppol ID.

[0020] User U is provided with a credit card associated with a user ID by the organization to which he belongs. User U uses the provided credit card to purchase items necessary for work.

[0021] The processing in the information processing system S will now be described. A user U presents a product to be purchased to a store clerk, and the store clerk reads the barcode attached to the product with a barcode reader, and inputs information about the product to be purchased by the user (for example, product name, product code, quantity, etc.) and information about the price of the product into a store terminal. The user U presents his / her credit card at the store ((1) in FIG. 1). At the store that accepts the presentation of the credit card, the store terminal 2 reads the presented credit card.

[0022] The store terminal 2 transmits payment data to the information processing device 1 ((2) in FIG. 1). The payment data is information indicating that payment has been made by credit card. The payment data includes at least the payment card number. The payment card number is a number used to identify the credit card used for payment.

[0023] Based on the payment data, the information processing device 1 determines whether the credit card is valid, and determines whether a user ID (Identification) (also called "user identification information") corresponding to the payment card number included in the payment data exists in the storage unit, and if so, identifies the user ID ((3) in FIG. 1). A user ID may be issued for each payment card number, or may be issued for each organization.

[0024] The information processing device 1 sends the supporting evidence data to the accounting processing device 3 via the invoice network N, addressed to the identified user ID ((4) in Figure 1). The supporting evidence data is information indicating that the transaction indicated by the payment data has taken place. The supporting evidence data includes the date and time of the payment, the store where the payment was made, the credit card number, and the payment amount. More specifically, the information processing device 1 sends the supporting evidence data to a relay device (not shown) corresponding to the identified user ID on the invoice network N. The relay device is a device for relaying the transmission of the supporting evidence data on the invoice network N.

[0025] In the above description, an example has been described in which the information processing device 1 transmits supporting document data to the accounting processing device 3, but this is not limiting. As an example, the information processing device 1 may transmit the supporting document data to an information terminal used by the user U.

[0026] By configuring the information processing system S in this manner, it becomes possible for supporting document data to reach the accounting processing device 3 via the invoice network N, and supporting document data in a format that can be processed by a computer can reach the accounting processing device 3.

[0027] [Configuration of information processing device 1] 2 is a block diagram showing the configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. The control unit 13 has an acquisition unit 131, an identification unit 132, a transmission unit 133, and a determination unit 134.

[0028] The communication unit 11 is a communication interface for transmitting and receiving data to and from other devices via a network. The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), an SSD (Solid State Drive), a hard disk drive, etc. The storage unit 12 stores in advance a program to be executed by the control unit 13.

[0029] The memory unit 12 stores user information that associates a registered card number, which is a card number for identifying a credit card, with a user ID, which is information for identifying the recipient user corresponding to the registered card number in the invoice network N. Figure 3 is a diagram showing an example of the data structure of user information stored in the memory unit 12. In the user information, a "registered card number," a "user ID," an "email address," and a "delivery address" are associated. The "user ID" indicates the user ID assigned to the organization that uses the credit card. The user information may also be associated with the user ID of the issuer of the supporting document data (the credit card company).

[0030] "Email address" is the address for sending supporting document data by email to the accounting officer of the organization corresponding to the "Registered card number," and is the address for sending supporting document data by email to the accounting processing device 3. "Shipping address" is the address for mailing a notice indicating the transaction details to the accounting officer. If there is no value in "User ID," this indicates that a user ID corresponding to the registered card number has not been registered, and therefore payment data cannot be sent via the invoice network N.

[0031] In the user information, for each registered card number, the destination of the user indicated by the registered card number in a means of transmitting supporting data that is different from the invoice network N is further associated. In other words, in the user information, an "email address" and a "delivery address" are associated as destinations in a means of transmitting that is different from the invoice network N. In addition, the user information may be associated with a fax number for sending a notification by fax indicating the transaction details indicated by the supporting data.

[0032] The control unit 13 is a processor such as a CPU (Central Processing Unit), etc. The control unit 13 executes a program stored in the storage unit 12, thereby functioning as an acquisition unit 131, an identification unit 132, a transmission unit 133, and a determination unit 134.

[0033] The acquisition unit 131 acquires the payment data from the terminal used at the affiliated store where the credit card payment was made. The acquisition unit 131 acquires the payment data from the store terminal 2.

[0034] The identification unit 132 identifies the user ID corresponding to the payment card number in the user information. The identification unit 132 refers to the user information stored in the storage unit 12 and identifies the user ID corresponding to the payment card number included in the payment data.

[0035] The transmitting unit 133 converts the payment data into a data format that can be transmitted over the invoice network N, and generates supporting data. When a user ID corresponding to the payment card number is identified, the transmitting unit 133 transmits the supporting data to the user corresponding to the identified user ID via the invoice network N. Specifically, the transmitting unit 133 inquires of a device that manages user IDs in the invoice network N about the address of a relay device corresponding to the user ID identified by the identifying unit 132, and identifies the destination relay device. The transmitting unit 133 transmits the supporting data to the identified relay device.

[0036] By configuring the information processing device 1 in this way, it becomes possible to easily process the evidence data when a credit card is used in the same way as other evidence data.

[0037] However, if the user information indicates that the user corresponding to the credit card number included in the payment data is a user who cannot obtain supporting data via the invoice network N, the information processing device 1 may be configured to send the supporting data to the user by another means.

[0038] If the sending unit 133 cannot identify a user ID corresponding to the payment card number included in the payment data, it sends the supporting document data to a destination in a sending means that corresponds to the payment card number in the user information and that is different from the invoice network N. As an example, if the specifying unit 132 does not have a user ID value that corresponds to the payment card number included in the payment data in the user information, it specifies a destination in another sending means.

[0039] If an email address corresponding to the payment card number included in the payment data is registered in the user information, the identification unit 132 identifies the email address in the user information corresponding to the payment card number included in the payment data as the destination.The sending unit 133 then sends the supporting document data to the identified email address.If neither a user ID nor an email address is registered, the sending unit 133 performs processing to mail a notification of the transaction details indicated in the supporting document data to the address corresponding to the payment card number in the user information.

[0040] By configuring the information processing device 1 in this manner, the supporting data can reach the organization to which the user U belongs even when the invoice network N is not available, allowing, for example, an accounting staff member to check and process the supporting data.

[0041] However, for example, if supporting evidence data that does not conform to the standards of the invoice network N is transmitted to the invoice network N, unexpected problems may occur. Therefore, if the supporting evidence data is not suitable for transmission over the invoice network N, the information processing device 1 may be configured to transmit it by a means other than the invoice network N.

[0042] The determination unit 134 determines whether the supporting document data can be transmitted over the invoice network N. As an example, the determination unit 134 determines whether the supporting document data meets the criteria established for information to be transmitted over the invoice network N. As an example, the determination unit 134 determines that the supporting document data cannot be transmitted over the invoice network N if the supporting document data does not include the date on which the supporting document data was issued or if the supporting document data does not include information indicating the consumption tax rate.

[0043] If the user ID of the user who sent the evidence data cannot be identified, the determination unit 134 may determine that the evidence data cannot be transmitted over the invoice network N. The identification unit 132 refers to the user information based on the payment card number and identifies the user ID of the issuer of the evidence data. If the identification unit 132 cannot identify the user ID of the issuer, the determination unit 134 determines that the evidence data cannot be transmitted over the invoice network N.

[0044] When the determination unit 134 determines that the supporting document data cannot be transmitted over the invoice network N, the transmission unit 133 transmits the supporting document data to a destination on a transmission means different from the invoice network N that corresponds to the payment card number in the user information. When the determination unit 134 determines that the supporting document data cannot be transmitted over the invoice network N, the transmission unit 133 may transmit the supporting document data by email to an email address that corresponds to the payment card number in the user information, or may perform processing to mail a notification of the transaction details indicated in the supporting document data to the address that corresponds to the payment card number.

[0045] However, there may be cases where the supporting document data cannot be transmitted via the invoice network N due to a network failure or the like. Therefore, the information processing device 1 may be configured to transmit the supporting document data by other transmission means when it detects that the supporting document data cannot be transmitted via the invoice network N due to a failure of the invoice network N or the like.

[0046] Specifically, the determination unit 134 inquires whether or not the voucher data can be transmitted to a relay device that relays the voucher data in the invoice network N. When the determination unit 134 acquires information indicating that the voucher data can be transmitted from the relay device, the determination unit 134 causes the transmission unit 133 to transmit the voucher data via the invoice network N.

[0047] If the determination unit 134 obtains information indicating that the evidence data cannot be transmitted from the relay device or if the determination unit 134 cannot obtain information from the relay device, it determines that the evidence data cannot be transmitted via the invoice network N. If an email address is registered in the user information as the destination corresponding to the payment card number included in the payment data, the transmission unit 133 transmits the evidence data by email to that email address.

[0048] If the determination unit 134 determines that the supporting document data cannot be sent via the invoice network N and no destination for another transmission means is registered in the user information, the determination unit 134 records a log indicating that the supporting document data cannot be sent. This allows the accounting staff to refer to the log to identify the supporting document data that was not sent and to perform processing such as obtaining a paper receipt from the user U.

[0049] In this way, when the information processing device 1 detects that it is unable to send supporting document data via the invoice network N, it sends the supporting document data without going through the invoice network N, thereby achieving the effect of being able to notify the organization to which the user U belongs of the supporting document data even if a failure occurs in the invoice network N.

[0050] Meanwhile, companies may want their employees (users U) to use credit cards for specific purposes or at specific stores. There is also a need to send supporting data when a credit card is used for specific purposes or at specific stores via the invoice network N, automatically process the supporting data, and have the supporting data sent by email for unauthorized stores to be checked by an accounting staff member. Therefore, sending supporting data via the invoice network N on the condition that the credit card was used at a specific affiliated store improves convenience for companies (users).

[0051] Figure 4 is a diagram showing an example of the data structure of user information stored in memory unit 12 in this case. In this user information, a registered member store ID is further associated with each registered card number. The registered member store ID is identification information for identifying a member store that accepts credit card payments. When a card with a registered card number is used at a member store indicated by the registered member store ID, evidence data is sent to the member store and the user ID, etc., corresponding to the card.

[0052] The payment data further includes a payment member store ID (also referred to as "member store identification information"), which is identification information for identifying the member store where the credit card payment was made. The acquisition unit 131 acquires payment data from the store terminal 2, which further includes the member store ID indicating the store where the store terminal 2 is installed.

[0053] The identification unit 132 identifies a user ID in the user information that corresponds to the payment card number and payment affiliated store ID included in the payment data. The transmission unit 133 then transmits the supporting document data via the invoice network N to the identified user ID as the destination. Note that if the identification unit 132 cannot identify a user ID in the user information that corresponds to the payment card number and payment affiliated store ID, the transmission unit 133 may transmit the supporting document data using a destination in another transmission means that corresponds to the payment card number included in the payment data.

[0054] By configuring the information processing device 1 in this manner, it becomes possible to transmit supporting data over the invoice network N when used at a specific affiliated store, automating the processing of specific supporting data and making it easier to encourage checking of supporting data that does not meet the conditions, thereby improving convenience for the user company.

[0055] Incidentally, when user U uses a credit card, there are cases where it is desired to change the subsequent processing flow, such as whether or not to automate processing or check, depending on the location and purpose of use. For example, if user U cannot determine whether or not the transaction can be processed as an expense, it may be better not to transmit supporting document data via invoice network N. Therefore, the information processing device 1 may be configured so that user U can select the method of transmitting payment information when accepting payment using a credit card at a store.

[0056] The acquisition unit 131 acquires the method of transmitting the supporting document data selected by the credit card user when payment is made by credit card, in association with the payment data. When reading the credit card presented at the store, the user U operates the store terminal 2 and inputs the method of transmitting the supporting document data. As an example, the transmission method can be selected from transmission via the invoice network N, transmission by email, and paper mail. The store terminal 2 transmits payment data that further includes the input transmission method to the information processing device 1, and the acquisition unit 131 acquires this data. Note that the method of transmitting the supporting document data selected by the user U may be notified to a store employee, who then operates the store terminal 2 to input the method.

[0057] The identification unit 132 identifies an address that corresponds to the payment card number in the user information and that corresponds to the transmission method selected by the user U. The transmission unit 133 transmits the evidence data to the address identified by the identification unit 132.

[0058] As an example, when the following two conditions are met, the transmission unit 133 transmits the supporting document data via the invoice network N to the user indicated by the user ID in the user information corresponding to the payment card number included in the payment data. The first condition is when the transmission method associated with the acquired payment data indicates transmission via the invoice network N. The second condition is when a user ID corresponding to the payment card number is identified.

[0059] By configuring the information processing device 1 in this way, it is possible to transmit the evidence data based on the method selected by the user U. As a result, when the user U uses a credit card, it becomes possible to flexibly change the processing flow at the time of payment.

[0060] [Processing flow in information processing device 1] Fig. 5 is a flowchart showing the flow of processing in the information processing device 1. The flowchart shown in Fig. 5 starts from the point at which payment data is acquired.

[0061] The acquisition unit 131 acquires payment data (S01). The identification unit 132 references user information and identifies a destination corresponding to the payment card number included in the payment data (S02). The transmission unit 133 generates evidence data based on the payment data (S03).

[0062] The transmission unit 133 determines whether or not a user ID has been specified as the destination (S04). If a user ID has been specified as the destination (YES in S04), the transmission unit 133 transmits the evidence data via the invoice network N (S05). Then, the information processing device 1 ends the processing.

[0063] If the user ID is not specified as the destination (NO in S04), the transmission unit 133 transmits the evidence data to the specified destination (S06). Then, the information processing device 1 ends the process.

[0064] [Effects of information processing device 1] By configuring the information processing device 1 in this way, the evidence data when a credit card is used can be transmitted via the invoice network N and can be processed in the same way as other evidence data. As a result, the information processing device 1 can simplify the processing after receiving the evidence data.

[0065] The present invention has been described above using embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, all or part of the device can be configured by functionally or physically distributing or integrating any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiments resulting from the combination also have the effects of the original embodiments. [Explanation of symbols]
