[0009] Hereinafter, with reference to the drawings, an embodiment of an information processing device, an information processing method, and a program of the present invention will be described. Various devices for providing services to users and performing internal analysis, such as the "server" that will be described below, may be realized by a group of distributed devices, and each device may be operated by a different business operator. Furthermore, the owner of the hardware of the device (the provider of the cloud server) and the business that actually operates the device may also be different. The application program and the payment server work together to provide an electronic payment service. 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 and 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 may be 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. Alternatively, processing such as payment may be performed between the user and the store.

[0010] [Electronic payment service] FIG. 1 is a diagram showing an example of the configuration of an electronic payment system in which an electronic payment service is realized. The electronic payment service is realized mainly by a payment server 100. The electronic payment system that realizes the electronic payment service includes, 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, the payment server 100, and an information providing device 200. These devices communicate with each other, for example, 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. Some or all of the functional configuration included in the electronic payment system may be distributed in any form among multiple devices, or may be integrated into any device.

[0011] [User terminal device] 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] [First store terminal device] 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] [Second store terminal device] 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 app for affiliated stores or a browser. The interface 72 for affiliated stores accepts coupon settings and the like made 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 the 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 the app for affiliated stores.

[0014] [Information providing device] The information providing device 200 provides telephone number information 178, which will be described later, to the payment server 100. The telephone number information 178 may be information obtained by the payment server 100 itself instead of being provided by the information providing device 200.

[0015] [Payment server] 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.

[0016] 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.

[0017] 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.

[0018] 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 (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).

[0019] 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.

[0020] [Payment server functional configuration] 4 is a configuration diagram of the payment server 100. The payment server 100 includes, for example, a communication unit 110, a content providing unit 120, a payment processing unit 130, an information management unit 140, an information processing unit (processing unit) 150, and a storage unit 170. The components other than the communication unit 110 and the storage unit 170 are realized by, for example, 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), a GPU (Graphics Processing Unit), or a SOC (System On Chip), 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.

[0021] The storage unit 170 is a HDD, a flash memory, a RAM (Random Access Memory), or the like. 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, content information 174, affiliated store / shop information 176, and phone number information 178. Some of this information may be stored in the storage unit of the user terminal device 10. Details of each piece of information will be described later.

[0022] 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.

[0023] The 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 content providing unit 120 reads out necessary content from the content information 174 as appropriate 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. The above content may be generated by the payment application 20. In this case, the content providing unit 120 provides the payment application 20 with information required for generating the content.

[0024] 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.

[0025] [User information] 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, for example, a user URL, an account ID, a telephone number, a password, as well as information associated with an email address, a user ID, a name, an address, a date of birth, a registration date, a charge balance, a credit payment setting, a credit payment limit, a credit payment amount used, a credit payment available amount, a payment method setting, a bank account, a credit card number, charge history information, and payment history information. The user URL is used for a remittance process between users. When registering for the 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 can be set by the user at will (does not have to be set). Similarly, the email address, and the name, address, and date of birth are information that can be set by the user at will (does not have to be set). The registration date is the date on which the user registered for 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 an account.

[0026] The charge balance is information indicating the balance of electronic money set by a user by transferring money to an account in advance. Means of transfer include transfer from an ATM (Automatic Teller Machine) of a designated business (bank) and transfer from a registered bank account. The credit payment setting is information indicating whether or not the setting for enabling electronic payment by credit payment using the payment application 20 has been completed, and is set to either "completed" or "not completed". The credit payment limit is the credit payment limit that can be used each month, the credit payment usage amount is the amount of credit payment already used in the current month, and the credit payment available amount is the amount of credit payment that can be used in the current month, which is calculated by subtracting the credit payment usage amount from the credit payment limit. Although only one credit payment limit is shown in the figure, in reality, there is also a daily upper limit, and the lower of these may be set as the credit payment limit. Further details of the credit payment will be described later. The payment method setting is setting information indicating whether the user will perform electronic payment using the charge balance or payment by credit 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 used to deposit funds into an electronic payment service. Charge history information is a history of the user's previous transfers to the electronic payment service to increase the charge balance. Payment history information is information that indicates the details of payments made by the user for each payment (date and time, store ID of the store where the purchase was made, payment amount, payment method, etc.).

[0027] [Affiliated store / store information] 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.

[0028] The information management unit 140 acquires information provided by other server devices. 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.

[0029] The information management unit 140 acquires the phone number information 178 at a predetermined interval (for example, once a month) from the information providing device 200. The information management unit 140 stores the acquired phone number information 178 in the storage unit 170 and manages it.

[0030] The information processing unit 150 executes various processes using the telephone number information 178. The details of these processes will be described later.

[0031] [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.

[0032] The payment processing unit 130 performs electronic payment for users whose "setting information" is set to "credit payment (credit payment using code information)" as follows. Credit payment is a payment method 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 credit payment limit. In order to receive the credit payment service, a credit card provided by the operator of the electronic payment service may be required. The amount used in the credit 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 credit payment amount and subtracting the same amount from the available credit 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 credit payment amount at the time of provisional payment, an error notification is returned to the payment application 20.

[0033] [overview] The information processing unit 150 judges whether or not the telephone number has been determined to have changed from valid to invalid in the history information showing the history of the telephone number usage. When the information processing unit 150 judges that the telephone number has changed from valid to invalid in the history information, it notifies the user terminal device 10 (payment application 20) corresponding to the identification information of the user of the electronic payment service associated with the telephone number registered in the electronic payment service, regarding the telephone number.

[0034] The telephone number is, for example, a telephone number registered in user information 172. The telephone number is a telephone number required when using an electronic payment service. The telephone number is a telephone number used for SMS (Short Message Service) authentication of the electronic payment service. The user can change the telephone number by operating payment application 20.

[0035] [Flowchart (1)] 7 is a flowchart showing an example of the flow of processing executed by the information processing unit 150. First, the information processing unit 150 refers to telephone number information (S100). Next, the information processing unit 150 extracts subjects who satisfy a condition (S102). Next, the information processing unit 150 notifies the extracted subjects (S104). This ends one routine of the processing of this flowchart.

[0036] The conditions are, for example, that (1), (2), and (3) are satisfied. Note that (2) or (3) may be omitted. The information processing unit 150 determines whether the above conditions are satisfied. (1) The flag of the telephone number information 178 at a first time point is valid, and the flag of the telephone number information 178 at a second time point after the first time point is invalid.

[0037] FIG. 8 is a diagram for explaining the determination of condition (1). Phone number information 178 is information in which, for example, a time such as date and time, a phone number, and a flag indicating the status of the phone number are associated with each other. In the example of FIG. 8, "1" is a flag indicating that the phone number is valid, and "0" is a flag indicating that the phone number is invalid. "Valid" means that the phone number is in use. "Invalid" means that the phone number is not in use. FIG. 8 shows the state of the phone number flag for each month.

[0038] For example, the information processing unit 150 extracts, from among the telephone numbers registered in the user information 172, telephone numbers whose flags have changed from valid "1" to invalid "0" at the two most recent time points. For example, the information processing unit 150 extracts telephone numbers whose flags are valid "1" for July at the first time point in the most recent first predetermined period and whose flags are invalid "0" for August at the second time point. The extracted telephone numbers are telephone numbers that are registered in the user information 172 but are presumed not to be in use. For this reason, it is necessary to inquire of the user as to whether they have changed their telephone number and encourage them to do so.

[0039] In the above process, the determination may be made using three or more time points instead of two time points. For example, the information processing unit 150 may determine that the condition (1) is satisfied when the most recent time point (e.g., August in FIG. 8) is invalid "0" and two or more time points prior to that (e.g., June and July in FIG. 8) are valid. Also, the condition (1) may be that the most recent two or more time points are invalid "0".

[0040] (2) The telephone number registered with the electronic payment service has not been changed. For example, the information processing unit 150 determines whether or not the telephone number registered with the electronic payment service has not been changed during a second predetermined period based on the second time point. The second predetermined period may be, for example, a period including the first time point and the second time point, or a period not including the first time point and including the second time point. The second predetermined period may be, for example, the above-mentioned two months of July and August, or may be August.

[0041] The timing to start this process is a predetermined timing after obtaining the latest telephone number information 178. In the case where telephone number information 178 is obtained every month as in Fig. 8, this is the timing when the latest telephone number information 178 for August 2024 is obtained and before obtaining telephone number information 178 for September 2024. This process is performed, for example, every time updated telephone number information 178 is obtained.

[0042] (3) The account for the electronic payment service that is associated with the identification information of the user of the electronic payment service is in an available state. An available state refers to a state in which the user has not cancelled the registration for the electronic payment service, such as a state in which the account is available (active state) or a state in which it is temporarily unavailable (suspended state).

[0043] When it is determined that the above conditions are satisfied, the information processing unit 150 cooperates with the content providing unit 120 to provide a notification regarding the telephone number. The notification regarding the telephone number includes a notification to prompt the user to change the telephone number, a notification to prompt the user to confirm the registered telephone number, and the like.

[0044] [notification] The information processing unit 150 performs the above notification on a home screen. FIG. 9 is a diagram showing an example of an interface screen IM1 on which the notification is performed. The interface screen IM1 is a home screen. The home screen is, for example, a screen that is displayed after the payment application 20 is started. The interface screen IM1 includes, for example, code information, various menu buttons, a payment button for making a payment, and information IF1 that prompts the user to change the phone number. The information IF1 that prompts the user to change the phone number is, for example, an action banner such as "Please confirm your registered phone number." This makes it possible to prompt the user to confirm the phone number.

[0045] The information processing unit 150 may perform the above notification by push notification. Fig. 10 is a diagram showing an example of a screen IM2 on which the notification has been made. The screen IM2 is, for example, a screen displayed on the display unit of the user terminal device 10. The screen IM2 includes, for example, information IF2 that prompts the user to change the phone number. The information IF2 that prompts the user to change the phone number is, for example, "Has your phone number changed?" This makes it possible to prompt the user to confirm the phone number.

[0046] The information processing unit 150 may perform the above notification by any means, such as email, automated voice call, SMS, etc. The information processing unit 150 may perform the notification by a plurality of notification means, such as email and an action banner, for example.

[0047] [User actions in response to notifications] When a predetermined operation is performed on the interface screen IM1 or screen IM2, the information processing unit 150 displays an interface screen (for example, interface screen IM3) on the display unit of the user terminal device 10. The interface screen includes a change button for instructing to change the telephone number, a non-change button for instructing not to change the telephone number, and a close button for closing the interface screen. When the close button is operated, the information processing unit 150 again issues a notification regarding the telephone number after a predetermined period has elapsed, and when the change button or non-change button is operated, it does not again issue a notification regarding the telephone number.

[0048] 11 is a diagram showing an example of an interface screen IM3. The interface screen IM3 includes, for example, the user's registered phone number, a button B1 indicating that the phone number is to be changed to a new phone number, a button B2 indicating that the phone number is not to be changed, and a close button B3 for closing the interface screen IM3.

[0049] When button B1, which indicates a change to a new telephone number, is operated, information processing unit 150 causes an interface screen for inputting a new telephone number (not shown) to be displayed on the display unit. When a new telephone number is input into the interface screen and an operation for registering the new telephone number is performed, information processing unit 150 changes the telephone number in user information 172 to the new telephone number.

[0050] When the button B2, which indicates that the telephone number is not to be changed, is operated, the information processing unit 150 completes the process related to the notification. For example, since there are rare cases where the flag of the telephone number information 178 is incorrect, when the user confirms that there is no change, the process is considered to be completed. In this case, the conditions (1)-(3) are judged at the next timing (for example, the next month), and if the judgment is affirmative, a notification is issued.

[0051] When the close button B3 is operated, the information processing unit 150 closes the interface screen IM3. In this case, the information processing unit 150 generates the notification information 180. FIG. 12 is a diagram showing an example of the notification information 180. The notification information 180 includes, for example, the date and time when the close button B3 is operated and the date and time of the next notification. When the close button B3 is operated, the information processing unit 150 determines the date and time of the next notification based on the time when the close button B3 is operated. For example, the notification date and time is set to several days later (for example, three days later). For example, when the interface screen IM3 is transitioned to, the notification action banner in FIG. 9 described above disappears once, but when the close button B3 is operated, a notification is made several days later. This allows the information processing unit 150 to remind the user to change to a new phone number.

[0052] For example, if the phone number has not been changed, the user can predict that the process will end by operating button B2, but that if the phone number has been changed and button B1 is operated, registration of a new phone number will be required. It is predicted that operations for registration will be required to register a new phone number, and depending on the situation when interface screen IM3 is displayed, it may not be possible to take the time or effort. In this case, the user may operate close button B3. Even in such a case, the information processing unit 150 will remind the user, improving convenience for the user.

[0053] The information processing unit 150 may continue the process of notifying after a few days for a predetermined period (for example, two months) and stop the process after the predetermined period. In this way, if the user continues to operate the close button for a predetermined period, the information processing unit 150 considers that the phone number has not been changed and stops the above notification.

[0054] [Flowchart (2)] 13 is a flowchart showing another example of the flow of the process executed by the information processing unit 150. This process is an example of the flow of the process in a state in which the interface screen IM3 is displayed.

[0055] First, the information processing unit 150 judges whether or not an operation to change to a new telephone number has been performed (S200). If an operation to change to a new telephone number has been performed, the information processing unit 150 displays an interface screen for changing to the new telephone number on the display unit of the user terminal device (S202). When the user performs an operation to change by inputting a new telephone number, the information processing unit 150 performs a change process to change the telephone number in the user information 172 to the new telephone number (S204).

[0056] The information processing unit 150 determines whether or not an operation to change the telephone number to a new one has been performed and an operation to not change the telephone number has been performed (S206). If an operation to change the telephone number to a new one has been performed and an operation to not change the telephone number has been performed, the information processing unit 150 stores in the storage unit 170 that the telephone number has not been changed (S208).

[0057] If the operation to change to a new phone number has not been performed and the operation not to change the phone number has not been performed, the information processing unit 150 judges whether or not the operation to close the interface screen IM3 has been performed (S210). If the operation to close the interface screen IM3 has not been performed, the processing of one routine of this flowchart ends.

[0058] When an operation to close the interface screen IM3 is performed, the information processing unit 150 performs a notification after a predetermined period of time (S212). The information processing unit 150 generates notification information 180 and performs a notification of a change to a new telephone number based on the notification information 180. This ends the processing of one routine of this flowchart.

[0059] As described above, the payment server 100 can appropriately notify the user of whether or not the phone number has been changed to a new one. This makes it possible to more appropriately prompt the user to change the phone number.

[0060] [summary] For example, if a user changes his / her phone number, he / she may neglect to change the phone number registered with the electronic payment service. In this case, the user can notice the change in phone number through the above notification, and can operate the payment application 20 while logged in to perform SMS authentication or the like to change the phone number.

[0061] For example, if user A changes telephone number A to telephone number B, he or she can use the electronic payment service by updating telephone number A registered in the electronic payment service to telephone number B. If telephone number A becomes the telephone number of another user, user B, and user B registers telephone number A as user B's telephone number in the electronic payment service, user A may no longer be able to use the electronic payment service. Normally, when telephone number A that was used by another user is allowed to be used by the next user, it is allowed to be used after an idle period (2 or 3 months) has passed.

[0062] Therefore, by performing the above notification during the idle period, the information processing unit 150 can urge other users to change the registration to telephone number B before telephone number A is registered, and can cause the user to perform the operation to change the telephone number. This makes it possible to appropriately urge the user to change the telephone number before telephone number A is registered to user B (before it becomes difficult for user A to change from telephone number A to telephone number B).

[0063] [Utilization of other flags] In the above example, the process has been described with a focus on the valid flag "1" and the invalid flag "0." Other flags may also be considered, as follows. The other flags are, for example, as follows. · Temporary stop flag "3" -Error flag "4" Communication terminal flag "5"

[0064] The convenience suspension flag "3" is a flag indicating that the telephone number is unavailable due to the user's convenience. The error flag "4" is a flag indicating that there is a problem with the phone number itself (for example, the phone number is incorrect) or that the phone number is a special phone number such as a toll-free number. The communication terminal flag "5" is a flag indicating that the telephone number is a telephone number used for data communication (a telephone number assigned for data communication).

[0065] The information processing unit 150 performs a notification when the status (flag) of a telephone number changes from a predetermined state to invalid in the telephone number information 178. The status is when the telephone number cannot be used (disabled due to circumstances flag), when the telephone number is a predetermined special telephone number (error flag), or when the telephone number is a telephone number used for data communication (communication terminal flag).

[0066] Fig. 14 is a diagram for explaining the process of sending a notification in response to a change in status. When the convenience suspension flag changes from "3" to the invalid flag "0" as shown in Fig. 14, the information processing unit 150 sends a notification regarding a change in telephone number.

[0067] The information processing unit 150 may notify when the telephone number changes from valid to a predetermined status in the telephone number information 178. The status is, as above, that the telephone number is in a state where it cannot be used (disabled due to circumstances flag), that the telephone number is a predetermined special telephone number (error flag), or that the telephone number is a telephone number used for data communication (communication terminal flag).

[0068] Through the above process, the information processing unit 150 can appropriately notify the user of a change in the phone number in response to a change in the status of the phone number.

[0069] According to the embodiment described above, when the information processing unit 150 determines that the telephone number has changed from valid to invalid, it can more appropriately prompt the user to change his or her telephone number by notifying the user terminal device corresponding to the identification information of the user of the electronic payment service that is associated with the telephone number registered in the electronic payment service regarding the telephone number.

[0070] 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.
