Embodiment 1.
FIG. 1 is a block diagram showing the configuration of an information processing system 1 according to Embodiment 1. As shown in FIG. In FIG. 1 , an information processing system 1 is a system in which a client terminal 2 A 1 , a client terminal 2 A 2 , a server 3 and a store terminal 4 are connected via a network 5 . The information processing system 1 is used for settlement of commercial transactions performed by the user A1 using the prepaid card B1, and is used for settlement of commercial transactions performed by the user A2 using the prepaid card B2.

An existing electric communication line can be used for the network 5 . Network 5 is, for example, the Internet. The client terminals 2A1 and 2A2 are terminal devices capable of communicating with the server 3 via the network 5, and are, for example, smart phones, tablet terminals, or PCs (Personal Computers). In the following, it is assumed that the client terminals 2A1 and 2A2 are smartphones.

The server 3 performs processing for opening a prepaid card account. The server 3 is owned or used by, for example, a settlement operator that provides settlement services using prepaid cards.
Accounts opened by the server 3 include personal accounts and shared accounts. A personal account is an account that can only be used by one user. A shared account is an account that can be shared by multiple users. Both personal and shared accounts are available only to verified users.

Any user who does not have a personal account can request the server 3 to open a new personal account. For example, when a user A1 whose identity has not been verified attempts to open a personal account, the user A1 can transmit identity verification information about himself/herself to the server 3 through a so-called eKCY (electronic Know Your Customer) procedure. When the server 3 acquires the personal identification information about the user A1, the server 3 performs processing for opening a personal account for the user A1. It should be noted that the user A1 can also send, by mail or the like, an identity verification document in the form of a paper medium containing items that can be used to verify the identity of the user A1 to the settlement company.

When the server 3 opens a personal account for the user A1, the user A1 is issued a prepaid card for the personal account. The prepaid card to be issued is either a real card or a virtual card installed in the client terminal as an application program, or both. The server 3 associates and stores the identification information that can identify the user A1, the card number of the prepaid card for the personal account, and the identification information of the personal account. As a result, the user A1 who opened the personal account becomes a verified user whose identity verification information is managed by the server 3 .

When user A1, whose identity has not been verified, receives an invitation to open a shared account from another user according to the procedure for opening a shared account, which will be described later, the identity verification procedure is performed, and the account is shared with the other user. Some may only have a joint account for use with In this case as well, the user A1 is a verified user whose identity verification information is managed by the server 3 .

A new personal account opening request to the server 3 can be made by any user who does not have a personal account. It can only be done by users who have at least one, i.e. users whose identity has been verified.

For example, assume that user A1 already has a personal account and is about to open a new shared account that can be used in common with user A2 who is an acquaintance. The user A1 whose identity has been verified is the first user who can request the server 3 to open a shared account. It is a first terminal that can be used by one user. User A2 is a second user with whom the first user intends to share a shared account, and client terminal 2A2 is a second terminal that can be used by the second user.

When user A1 intends to open a shared account with user A2, user A1 uses client terminal 2A1 to transmit a shared account opening request to server 3 . At this time, a management screen provided by a management application for managing the account used by the user A1 is displayed on the display unit 2D (described later) provided in the client terminal 2A1. The management application is, for example, an application pre-installed in the client terminal 2A1 and executed in the client terminal 2A1. Alternatively, the management application is, for example, a management application executed in the server 3 to provide the client terminal 2A1 with an account management function through the network 5. FIG. The user A1 transmits a request for opening a shared account to the server 3 by operating the management screen displayed on the screen of the client terminal 2A1. When the server 3 acquires a shared account opening request from the client terminal 2A1 on which the management screen is displayed, the server 3 transmits basic information for generating invitation information for opening a shared account to the client terminal 2A1. The basic information includes information indicating that user A1 has requested to open a shared account. The basic information is generated by the server 3 as a so-called token consisting of a predetermined character string, for example, and transmitted to the client terminal. Tokens generated as basic information are unique and are issued for each shared account opening request, and even if the same user requests opening, a token consisting of an individual character string is generated each time.

The client terminal 2A1 uses the basic information received from the server 3 to generate invitation information for opening a shared account. The invitation information includes information for accessing a specific URL provided by the server 3 . The invitation information is generated in the form of a code image such as a two-dimensional barcode such as a QR code (registered trademark) or a one-dimensional barcode, or a code represented by a character string. The client terminal 2A2 accesses the server 3 based on the invitation information generated by the client terminal 2A1.

When the server 3 is accessed from the client terminal 2A2 based on the invitation information for opening a shared account, the server 3 determines whether the user It is determined whether or not A2 has been verified. When the server 3 determines that the identity of the user A2 has been verified, the server 3 transmits display control information to the client terminals 2A1 and 2A2. The display control information in this case is control information for displaying an approval confirmation screen for opening a shared account on a display unit 2D (described later) provided in each of the client terminals 2A1 and 2A2.

The client terminals 2A1 and 2A2 display an approval confirmation screen on each display unit 2D (described later) based on the display control information. The approval confirmation screen displayed on the client terminal 2A1 used by the user A1 contains at least information about the user A2, and thus the user A1 knows that he/she is going to open a shared account with the user A2. Based on the information displayed on the approval confirmation screen, the user A1 determines whether or not to approve the opening of the shared account with the user A2. The approval confirmation screen displayed on the client terminal 2A2 used by the user A2 includes at least information about the user A1, and it can be understood that the user A1 is about to open a shared account with the user A2. It is preferable that the information about user A1 includes the personal name confirmed when user A1 is authenticated, and the same applies to information about user A2. Based on the information displayed on the approval confirmation screen, the user A2 determines whether or not to approve the opening of the shared account with the user A1. The user A1 who approves the opening of the shared account uses the client terminal 2A1 to transmit approval information indicating that the opening of the shared account is approved to the server 3 . Similarly, user A2 who approves opening a shared account transmits approval information to server 3 using client terminal 2A2. Each approval confirmation screen includes, for example, an approval button (refer to the "to card issuance" column S7 in FIG. 8 described later) and a disapproval button (refer to the "cancel opening of shared account" column S6 in FIG. 8 to be described later). , and users A1 and A2 can use these buttons to send approval information or disapproval information to the server 3, respectively.

When the server 3 acquires the approval information from both the client terminals 2A1 and 2A2, it performs processing to open a shared account shared by the users A1 and A2. When a shared account shared by users A1 and A2 is opened by the server 3, a prepaid card B1 for the shared account is issued to the user A1, and a prepaid card B2 for the shared account is issued to the user A2. be done. The prepaid card to be issued is either a real card or a virtual card installed in the client terminal as an application program, or both. For example, the server 3 associates and stores the identification information of the user A1, the identification information of the user A2, the card number of the prepaid card B1, the card number of the prepaid card B2, and the identification information of the shared account. In this way, the server 3 establishes a shared account shared by users A1 and A2. This newly opened shared account is an account different from both the existing personal account and existing shared account used by user A1 and the existing personal account and existing shared account used by user A2. The prepaid cards B1 and B2 for the shared account are cards independent of the prepaid cards for the existing accounts as described above, and the card numbers of the prepaid cards B1 and B2 are issued with a number different from the card number of the prepaid card. Further, although the card number of the prepaid card B1 for the shared account and the card number of the prepaid card B2 for the shared account are also issued as different numbers, they are issued in association with each other and payments are made from one shared account.

The store terminal 4 is a terminal device installed in a store of a member store that allows settlement using a prepaid card. For example, assume that prepaid cards B1 and B2 are prepaid cards issued for a shared account shared by users A1 and A2, as described above. In addition to the function of opening an account, the server 3 has a function of managing settlement of commercial transactions using prepaid cards. When a user A1 settles a commercial transaction using a prepaid card B1 at a store, the store terminal 4 reads the card information stored in the prepaid card B1 and transmits the settlement information to the server 3 via the network 5. - 特許庁The payment information includes the identification information of the member store where the payment was made, the payment amount, and the card information. The card information includes the card number of the prepaid card B1.

When the server 3 receives the payment information transmitted from the shop terminal 4, it identifies the shared account of the prepaid card B1 corresponding to the card number. Next, the server 3 pays the amount indicated by the settlement amount to the affiliated store from the specified balance of the shared account. At this time, the server 3 stores, for example, the date and time when the server 3 processed the payment to the member store, calculates the balance of the shared account after the payment processing, and stores it together with the date and time.

In addition, when the store terminal 4 transmits the payment information to the server 3 via the network 5, it may go through one or a plurality of other servers (not shown in FIG. 1) other than the server 3. FIG. Another server is, for example, a server provided by a credit card company.
Also, the commercial transactions using the prepaid cards B1 and B2 have been described as commercial transactions in the case where the store is a real store, but they may be commercial transactions with stores on the Internet by operating the client terminal 2A1 or 2A2.

In the information processing system 1, an identity-verified user A1 uses the client terminal 2A1 to request the server 3 to open a shared account, generate invitation information, and approve the opening of the shared account. However, by using the client terminal 2A2 to access the server based on the invitation information and approve the opening of the shared account, the shared account of the users A1 and A2 is opened. Therefore, the server 3 can provide a procedure for easily opening a shared account between intended users.

FIG. 2 is a block diagram showing the configuration of client terminals 2A1 and 2A2. As shown in FIG. 2, the client terminals 2A1 and 2A2 are provided with a communication section 2B, a calculation section 2C, a display section 2D, an operation section 2E and a photographing section 2F.

The communication unit 2B is, for example, a communication device capable of mobile communication by a communication method such as LTE, 3G, 4G or 5G, and a server 3 connected to the network 5 via the network 5. , etc. (only the server 3 is shown in FIG. 2). Also, the communication unit 2B may include short-range wireless communication means such as Bluetooth (registered trademark). The calculation unit 2C controls the overall operations of the client terminals 2A1 and 2A2. Further, for example, when a management application is installed in the client terminal 2A1 or 2A2, the calculation unit 2C realizes various functions by executing a management application for managing accounts for prepaid cards. For example, when the management application is executed by the server 3, the calculation unit 2C implements various functions by receiving instructions from the server 3. FIG.

The display unit 2D is a display device provided in each of the client terminals 2A1 and 2A2. The display unit 2D is, for example, an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence) display device. The operation unit 2E is an input device that receives operations for the screen display of the display units 2D of the client terminals 2A1 and 2A2. For example, when the client terminals 2A1 and 2A2 are smartphones or tablet terminals, the operation unit 2E is a touch panel provided integrally with the screen of the display unit 2D. Moreover, when the client terminals 2A1 and 2A2 are PCs, the operation unit 2E is, for example, a mouse or a keyboard.

The photographing unit 2F is a photographing device provided in each of the client terminals 2A1 and 2A2. When the client terminals 2A1 and 2A2 are smart phones, the imaging unit 2F is a photographic device having an image sensor, which is standardly installed in smart phones. Further, for example, when the client terminals 2A1 and 2A2 are tablet terminals or laptop PCs, the imaging unit 2F is a photographing device having an image sensor, which is standardly installed in the tablet terminal or laptop PC. . If the client terminals 2A1 and 2A2 are, for example, desktop PCs not equipped with a photographing device as standard equipment, the photographing unit 2F has an image sensor additionally connected to the desktop PC. It is a photographing device. A CMOS image sensor or a CCD image sensor can be used for the image sensor.

The calculation unit 2C includes a management screen display unit 20, an opening request transmission unit 21, a basic information acquisition unit 22, an invitation information generation unit 23, an output unit 24, a display control information acquisition unit 25, an approval confirmation screen display unit 26, and an approval confirmation result. A transmission unit 27 , a reading function activation unit 28 , and an identity verification complete information transmission unit 29 are provided. For example, by executing the management application for managing the prepaid card account, the calculation unit 2C executes the management screen display unit 20, the opening request transmission unit 21, the basic information acquisition unit 22, the invitation information generation unit 23, Functions of an output unit 24, a display control information acquisition unit 25, an approval confirmation screen display unit 26, an approval confirmation result transmission unit 27, a reading function activation unit 28, and an identity verification completed information transmission unit 29 are realized.

The management screen display unit 20 displays a management screen for managing existing prepaid card accounts on the display unit 2D. The management screen is provided by a management application for managing prepaid card accounts. For example, when the user A1 installs a management application on the client terminal 2A1, the user A1 operates the client terminal 2A1 to download the management application from the application purchase store and install it on the client terminal 2A1. When the management application is installed in the client terminal 2A1, the user A1 can register as a user for the prepaid card service provided by the information processing system 1 using the function provided by the management application. Further, when the user A1 logs in to the management application and uses the function provided by the management application to transmit the personal identification information to the server 3, the server 3 stores the prepaid card account used by the user A1. A prepaid card for the account is issued to the user A1. When an account used by user A1 is opened and a number identifying the issued prepaid card is entered into the management application installed in client terminal 2A1, the prepaid card is validated and the management application allows user A1 to prepaid. It becomes possible to provide a management screen for managing card accounts. That is, the management screen display unit 20 realized by executing the management application can display the management screen for managing the account on the display unit 2D. For example, the management screen includes an icon for accepting a request to open a shared account. When the user A1 operates the icon on the management screen using the operation unit 2E, the opening request transmission unit 21 is activated.

The opening request transmission unit 21 transmits a request for opening a shared account to the server 3 that performs prepaid card account opening processing based on the operation performed on the management screen. For example, when the opening request transmission unit 21 is activated based on an operation performed on the management screen, it generates a request for opening a shared account, and transmits the generated opening request to the server 3 via the network 5 by the communication unit 2B. Send to For example, an opening request from the client terminal 2A1 displaying a management screen provided by a management application for managing the prepaid card account used by the user A1 (hereinafter referred to as "user A1's request to open a shared account"). , the shared account opening request includes the identification information of the requesting user A1.

The basic information acquisition unit 22 acquires from the server 3 basic information for generating invitation information for opening a shared account. When the server 3 receives a shared account opening request from the user A1, the server 3 uses the identification information of the user A1 included in the opening request to generate a token used to generate the invitation information for opening the shared account, The generated token is sent to the client terminal 2A1. The basic information acquisition unit 22 acquires the token received by the communication unit 2B and outputs the acquired token to the invitation information generation unit 23 .

The invitation information generation unit 23 generates invitation information using the basic information based on the operation performed on the management screen. Information for accessing the server 3 is included in the invitation information. The information for accessing the server is, for example, a parameter-added URL (Uniform Resource Locator) for accessing a service dedicated to opening a shared account with user A1 provided by the server 3, and the parameter is the communication unit 2B. contains the token received by Also, the information for accessing the server may be, for example, the token itself, that is, the basic information itself. The invitation information generation unit 23 generates invitation information in the form of a code image or a character string. For example, the invitation information generation unit 23 generates a QR code, which is a code image representing invitation information. Also, for example, the invitation information generation unit 23 may generate a one-dimensional barcode indicating the invitation information, or may generate a character string indicating the invitation information.

The output unit 24 outputs the invitation information in a form that can be used by an external terminal such as the client terminal 2A2. For example, when the invitation information generated by the invitation information generation unit 23 of the client terminal 2A1 is a code image such as a QR code, the output unit 24 of the client terminal 2A1 displays the invitation information on the display unit 2D of the client terminal 2A1.

Images can be read.

Also, the output unit 24 may transmit the invitation information to the external terminal. For example, when the invitation information for opening a shared account by the user A1 is in the form of a code image or a character string, the output unit 24 of the client terminal 2A1 sends the invitation information to the client terminal 2A2, which is an external terminal, using the communication unit 2B. Send. The output unit 24 of the client terminal 2A1 can transmit the invitation information to the client terminal 2A2 via the network 5, for example, by e-mail, chat, or the like. Also, the communication unit 2B of the client terminal 2A1 may transmit the invitation information to the client terminal 2A2 using short-range wireless communication such as Bluetooth. The client terminal 2A2 that has acquired the invitation information transmitted from the client terminal 2A1 can read the invitation information as a code image or character string displayed on the display unit 2D of the client terminal 2A2 using a known reading technique. can.

The display control information acquisition unit 25 acquires from the server 3 display control information for displaying the approval confirmation screen for opening a shared account. When the server 3 determines that the identity of the user A2 has been verified in the process of opening the shared account of the users A1 and A2, the server 3 transmits display control information to the client terminals 2A1 and 2A2. The display control information in this case is control information for displaying an approval confirmation screen for opening a shared account on the display units 2D of the client terminals 2A1 and 2A2.

The approval confirmation screen display section 26 of each of the client terminals 2A1 and 2A2 displays the approval confirmation screen on each display section 2D based on the display control information. The approval confirmation screen displayed on the client terminal 2A1 used by the user A1 includes at least information on the user A2 who is invited to open a shared account. Further, the approval confirmation screen displayed on the client terminal 2A2 used by the user A2 includes at least information regarding the user A1 who is the inviter of opening a shared account. For example, information about user A1 includes text information indicating the name of user A1, and information about user A2 includes text information indicating the name of user A2. The user A1 refers to the information indicating the user A2 on the approval confirmation screen, and uses the operation unit 2E to determine whether or not to approve the opening of the shared account with the user A2. Similarly, the user A2 refers to the information indicating the user A1 on the approval confirmation screen, and uses the operation unit 2E to determine whether or not to approve the opening of the shared account with the user A1.

The approval confirmation result transmission unit 27 transmits to the server 3 information indicating whether or not to approve the opening of the shared account based on the operation performed on the approval confirmation screen. Approval confirmation screens displayed on the display units 2D of the client terminals 2A1 and 2A2 include, for example, an approval button (refer to the "to card issuance" column S7 in FIG. 8 described later) and a disapproval button (see FIG. 8 described later). (see S6), and users A1 and A2 can select these buttons to transmit approval information or disapproval information to the server 3. For example, when the user A1 approves opening a shared account with the user A2, the approval confirmation result transmission unit 27 of the client terminal 2A1 transmits approval information to the server 3 through the communication unit 2B. Similarly, when the user A2 approves opening a shared account with the user A1, the approval confirmation result transmission unit 27 of the client terminal 2A2 transmits approval information to the server 3 through the communication unit 2B.

The reading function activation unit 28 activates a reading function for reading invitation information based on an operation performed on the management screen. The reading function activated by the reading function activation unit 28 is, for example, a code image reading function using the imaging unit 2F. For example, when the client terminal 2A2 reads the invitation information as a QR code displayed on the display unit 2D of the client terminal 2A1, the reading function activation unit 28 of the client terminal 2A2 uses the operation unit 2E to read the management screen. The imaging unit 2F is activated based on the read operation performed, and the imaging unit 2F is made to read the QR code. Further, the reading function activated by the reading function activation unit 28 is, for example, a function of reading a code image or character string displayed on the display unit of the client terminal (hereinafter referred to as "display screen reading function"). For example, when the client terminal 2A2 reads the invitation information as a QR code displayed on the display unit 2D of the client terminal 2A1, the reading function activation unit 28 of the client terminal 2A2 uses the operation unit 2E to read the management screen. Based on the read operation performed, the display screen reading function is activated to read the QR code displayed on the display unit 2D of the client terminal 2A2.

When the invitation information is read using the reading function activated by the reading function activation unit 28, the identity-confirmed information transmitting unit 29 transmits information indicating that the identity of the user using the existing prepaid card has been confirmed. Send to server 3.
As described above, the reading function activation unit 28 activates the reading function by an operation performed on the management screen. Then, for example, when the client terminal 2A2 can display the management screen, it means that the user A2 who uses the client terminal 2A2 is also the user who uses the existing prepaid card account managed using the management screen. means that That is, in this case, the user who "uses an existing prepaid card" is user A2, and user A2 has already been verified. The management application can then recognize that the currently logged-in user is user A2. Therefore, the identity verification completion information transmitting unit 29 of the client terminal 2A2 can transmit to the server 3 a token indicating that the identity of the user A2 has been verified.

In this way, for example, when the imaging unit 2F of the client terminal 2A2 reads the invitation information as a QR code, the client terminal 2A2 accesses the server 3 based on the read information, 29 uses the communication unit 2B to transmit to the server 3 information indicating that the identity of the user A2 has been verified. Information indicating that the identity has been verified is transmitted in the form of a token, for example.

As a method for the client terminal 2A2 to access the server 3 based on the invitation information, as described above, there is a method for the client terminal 2A2 to read the invitation information as a code image or a character string. If the included information for accessing the server 3 is the basic information itself sent from the server 3 as described above, that is, the token itself, for example, the user A2 displays on the display unit 2D of the client terminal 2A2 There is also a method of accessing the server 3 by entering character information indicated by the token on the displayed dedicated screen.

FIG. 3 is a block diagram showing the configuration of the server 3. As shown in FIG. As shown in FIG. 3, the server 3 includes a communication section 3A, a calculation section 3B and a storage section 3C. The communication unit 3A communicates with the client terminal 2A1, the client terminal 2A2, or the shop terminal 4 via the network 5 (the shop terminal is not shown in FIG. 3). For example, the communication unit 3A can communicate via the network 5 with the client terminal 2A1 or 2A2 having the communication unit 2B, which is a communication device capable of mobile communication using a communication method such as LTE, 3G, 4G or 5G. is. The calculation unit 3B controls the overall operation of the server 3. FIG. The calculation unit 3B implements various functions by executing an account opening application for opening an account for a prepaid card.

The storage unit 3C stores an application for opening an account, and stores data used for arithmetic processing of the arithmetic unit 3B. The storage unit 3C stores identification information of user A1, identification information of user A2, the card number of prepaid card B1 used by user A1 in the shared account, the card number of prepaid card B2 used by user A2 in the shared account, and shared account identification information are stored in association with each other. When the server 3 executes a management application to provide the client terminals 2A1 and 2A2 with an account management function through the network 5, the storage unit 3C also stores the management application.

The calculation unit 3B includes a basic information transmission unit 31, a determination unit 32, a display control information transmission unit 33, and an account opening unit . The functions of the basic information transmission section 31, the determination section 32, the display control information transmission section 33, and the account opening section 34 are realized by the calculation section 3B executing the application for opening an account. The account opening application is activated in response to acquisition of an account opening request by the server 3 .

The basic information transmission unit 31 acquires a request for opening a shared account from a client terminal on which a management screen provided by a management application for managing accounts used by users is displayed, and generates invitation information for opening a shared account. Basic information for doing so is sent to the client terminal. For example, when the client terminal 2A1 can display a management screen for managing the account used by the user A1, it means that the user A1 using the client terminal 2A1 can use the management screen to manage the account. It means that the user is already using it. In this case, the user A1 is a verified user. For example, when the user A1 whose identity has been verified uses the client terminal 2A1 to make a request to open a shared account, the basic information transmission unit 31 receives the request to open a shared account from the client terminal 2A1. The communication unit 3A transmits a token for generating the invitation information for the client terminal 2A1 to the client terminal 2A1.

When the client terminal accesses the server 3 based on the invitation information, the determining unit 32 determines whether or not the user of the client terminal has been verified according to whether or not information indicating that the user of the client terminal has been verified is acquired. It is determined whether or not the For example, when the client terminal 2A2 accesses the server 3 based on the invitation information, the determination unit 32 determines whether the communication unit 3A has received a token indicating that the identity of the user A2 has been verified from the client terminal 2A2. It is determined whether or not the user A2 has been verified. The determination unit 32 determines that the identity of the user A2 has been verified when the token is received, and determines that the identity of the user A2 has not been verified when the token is not received.

When the determination unit 32 determines that the identity of the user A2 has been verified, the display control information transmission unit 33 transmits display control information for displaying an approval confirmation screen for opening a shared account to the client terminal 2A1 and the client terminal 2A2. do. For example, the storage unit 3C stores information about users whose identity has been verified. Therefore, when the users A1 and A2 have been verified as described above, information on each of the users A1 and A2 is stored in the storage unit 3C. When it is determined that the user A2 has been verified, the display control information transmission unit 33 generates display control information using the information regarding the user A1 and the information regarding the user A2 read from the storage unit 3C, and transmits the generated display control information. are transmitted to the client terminals 2A1 and 2A2 by the communication unit 3A.

The account opening unit 34 acquires personal identification information regarding the user A1, and performs processing for opening an account used by the user A1. Further, when the account opening unit 34 acquires approval information indicating approval for opening a shared account from both the client terminal 2A1 and the client terminal 2A2 on which the approval confirmation screen is displayed, the user A1 and the user A2 share the approval information. Open the shared account to be used. For example, when the account opening unit 34 opens a shared account shared by user A1 and user A2, the identification information of user A1, the identification information of user A2, and the prepaid card B1 used by user A1 in the shared account. number, the card number of the prepaid card B2 used by the user A2 in the shared account, and the identification information of the shared account are associated and stored in the storage unit 3C.

FIG. 5 is a timing chart showing opening of a prepaid card shared account according to the first embodiment. The first terminal in FIG. 5 is the client terminal 2A1, the second terminal in FIG. 5 is the client terminal 2A2, and the server in FIG. Further, it is assumed that user A1 is an inviting user who invites user A2 to open a shared account, and user A2 is an invited user invited by user A1 to open a shared account.

In the client terminal 2A1, the opening request transmission unit 21 transmits a shared account opening request to the server 3 using the communication unit 2B based on the operation performed on the management screen using the operation unit 2E (step ST1 ). FIG. 6 is a screen diagram showing an overview of operations on the management screen 2D1 of the client terminal 2A1. The management screen display unit 20 of the client terminal 2A1 displays the management screen 2D1 on the display unit 2D. The management screen 2D1 is a screen for receiving various settings for managing accounts for prepaid cards. For example, when the user A1 uses the operation unit 2E to select and operate the "open a shared account" field S1 on the management screen 2D1, the opening request transmission unit 21 uses the communication unit 2B to request opening of a shared account. to the server 3.

When the server 3 receives the shared account opening request from the user A1, the server 3 uses the identification information of the user A1 included in the opening request to transfer the token used for generating the invitation information for opening the shared account to the client terminal 2A1. (step ST2). In the client terminal 2A1, the basic information acquisition unit 22 outputs the token acquired from the server 3 using the communication unit 2B to the invitation information generation unit 23. FIG. The management screen display unit 20 displays the management screen 2D2 on the display unit 2D when the opening request transmission unit 21 requests to open a shared account.

The management screen 2D2 is a screen for receiving operations related to opening a shared account, and is provided with, for example, a "display your QR code" column S3. For example, the user A1 uses the operation unit 2E of the client terminal 2A1 to operate the "display your QR code" field S3 on the management screen 2D2, so that the invitation information generation unit 23 The token is used to generate a QR code showing invitation information for opening a shared account.

The output unit 24 of the client terminal 2A1 outputs the invitation information generated by the invitation information generation unit 23 (step ST3). For example, as shown in FIG. 6, the output unit 24 of the client terminal 2A1 displays a small screen 2D3 including the QR code C indicating the invitation information on the management screen 2D2 on the display unit 2D of the client terminal 2A1.

In addition to the QR code C indicating the invitation information, the small screen 2D3 is provided with a "Send QR code as an image" field S4. The user A1 uses the operation unit 2E to operate the "Send QR code as an image" field S4 on the small screen 2D3, thereby inputting the information necessary to specify and transmit to the client terminal 2A2 (not shown). Via the screen, the output unit 24 uses the communication unit 2B to transmit an image including the QR code C to the client terminal 2A2. When the communication unit 2B of the client terminal 2A2 receives the image including the QR code C from the client terminal 2A1, the client terminal 2A2 displays the management screen 2D2 on the display unit 2D.

In the following, the operation of the above "Send QR code as an image" field S4 is not performed, and the small screen 2D3 including the QR code C indicating the invitation information is displayed on the management screen 2D2 on the display unit 2D of the client terminal 2A1. It shall be
Next, when the user A2 uses the operation unit 2E to operate the “read QR code” column S2 of the management screen 2D1 displayed on his/her own client terminal 2A2, the reading function activation unit 28 of the client terminal 2A2 The part 2F is activated and the QR code C is read.

FIG. 7 is a screen diagram showing an outline of reading the invitation information, and shows a case where the client terminal 2A2 directly reads the QR code C displayed on the client terminal 2A1. An image 2D4 processed by the image sensor of the imaging unit 2F is displayed on the display unit 2D of the client terminal 2A2, and a frame S5 is superimposed on the image 2D4. The imaging unit 2F directly reads the QR code C when the QR code C is positioned inside the frame S5.

Based on the acquired invitation information, the identity-confirmed information transmission unit 29 of the client terminal 2A2 accesses the server 3 using the communication unit 2B, and transmits to the server 3 information indicating that the identity of the user A2 has been confirmed. (step ST4). For example, in the client terminal 2A2, when the reading function provided by the management application reads the QR code indicating the invitation information, that is, the reading function activated by operating the "read QR code" field S2 on the management screen 2D1 reads the QR code, the identity verification complete information transmitting unit 29 is activated. Based on the URL included in the invitation information, the identity-verified information transmission unit 29 accesses the server 3 using the communication unit 2B and transmits to the server 3 information indicating that user A2 has been identity-verified. For example, the identity verification completion information transmitting unit 29 transmits to the server 3 a token indicating that the identity of the user A2 has been verified.

Here, the reading function activating unit 28 can activate the reading function by an operation performed on the management screen only when the identity has been verified. That is, when the client terminal 2A2 can display the management screen provided by the management application, it means that the user A2 using the client terminal 2A2 has already used the prepaid card account managed using the management screen. It means that you are also a user That is, in this case, user A2 has already been verified. Also, the management application can recognize that the logged-in user is user A2. Therefore, the identity verification completion information transmitting unit 29 of the client terminal 2A2 can transmit to the server 3 a token indicating that the identity of the user A2 has been verified.

It should be noted that when the operation in the above "Send QR code as an image" field S4 is performed and the invitation information is transmitted to the client terminal 2A2 using the communication unit 2B, the communication unit 2B of the client terminal 2A2 receives the invitation information. do. In this case as well, when the reading function is activated by an operation performed on the management screen and the invitation information is read, the identity-confirmed information transmission unit 29 of the client terminal 2A2 reads the invitation information based on the URL included in the invitation information. Then, the server 3 can be accessed using the communication unit 2B, and information indicating that the identity of the user A2 has been verified can be transmitted to the server 3. FIG.

On the other hand, the client terminal 2A2 can read invitation information such as a QR code output from the client terminal 2A1 by using a photographing function using the photographing unit 2F provided by an application other than the management application. In this case, the information indicating that the identity of user A2 has been confirmed is not immediately transmitted by the identity-confirmed information transmitting unit 29 based on the fact that the function provided by the management application is used.

As described above, when the invitation information is read using the shooting function using the shooting unit 2F provided by an application other than the management application, when the client terminal 2A2 tries to access the URL indicated by the invitation information, By the client terminal 2A2 converting the URL into a deep link and cooperating, the behavior on the client terminal 2A2 can be changed depending on whether or not the management application has been installed on the client terminal 2A2. . In addition, since the deep link itself is a well-known technology, detailed description of the technology is omitted.

As a specific behavior, for example, when it is determined that the management application is not installed in the client terminal 2A2, the client terminal 2A2 accesses a server (not shown in FIG. 1) that manages the application purchase store, The download screen of the prepaid card management application is displayed. As a result, the user A2 is guided to download the management application and perform the personal identification procedure.
Then, the user A2 downloads and installs the management application on the client terminal 2A2 according to the guidance, registers as a user for the prepaid card service provided by the information processing system 1, and performs the personal identification procedure. It is possible to return to the procedures for opening a shared account with user A1.

Further, for example, when it is determined that the management application is installed in the client terminal 2A2, the management application is activated. When the management application is started with the user A2 logged in, the management screen display unit 20 displays the management screen, after which the management application can confirm whether or not the identity of the user A2 has been verified.

As a result of the confirmation, if the identity has been confirmed, the identity-confirmed information transmission unit 29 transmits to the server 3 information indicating that the user A2 has been identity-confirmed.
On the other hand, as a result of the above confirmation, if the identity has not been confirmed, the identity-confirmed information transmitting unit 29 transmits information indicating that the user logging in to the management application installed in the client terminal 2A2 has not been identity-confirmed. do. At this point, the identity of the user A2 has not been verified, so the server 3 is not sent information on whether or not the user logging into the management application is the user A2. In the following description, it is assumed that the user logging into the management application is user A2.

When the determination unit 32 of the server 3 acquires information indicating that the identity of the user A2 who has logged in to the management application has not been verified, it determines that the identity of the user A2 has not been verified. When the determination unit determines that the user A2 has not been verified, the display control information transmission unit 33 causes the client terminal 2A2 to display a guidance screen for guiding the user A2 to perform the verification procedure. Send display control information. The client terminal 2A2 sends information indicating that the identity of the user logged in to the management application has not been verified to the server 3 by the identity verification completion information transmission unit 29, and the above guidance is performed by the function of the management application itself. A screen may be displayed. In this case, the display control information for displaying the guidance screen is not transmitted from the server 3 . Then, after that, when the user A2 transmits the personal identification information to the server 3 according to the guidance of the guidance screen, the display control information transmission unit 33 acquires the personal identification information regarding the user A2 from the client terminal 2A2, Returning to the processing after step ST5 in FIG. 5, the client terminals 2A1 and 2A2 are sent display control information for displaying the approval confirmation screen for opening a shared account.

As described above, the management application has been started, but if the management application is started without the user A2 logging in, the management application displays the login screen. After that, when the user A2 logs in, the same processing as when the management application is started while logged in is performed.
Although the example in which the invitation information is in the form of a QR code has been shown so far, the invitation information may be in the form of a one-dimensional bar code or a character string. Regardless of the format of the invitation information, the client terminal 2A1 displays the invitation information on the display unit 2D of the client terminal 2A1 and outputs it, or transmits and outputs the invitation information to the client terminal 2A2. can do. In addition, the client terminal 2A2 utilizes a reading function provided by the management application or a reading function provided by an application other than the management application according to the format of the invitation information and the format of output of the invitation information by the client terminal 2A1. It may be possible to read the invitation information.

Further, when the client terminal 2A2 accesses the server 3 after a certain period of time has passed since the basic information (for example, token) was transmitted from the server 3 to the client terminal 2A1, the process of opening the shared account is canceled. . For example, the fixed time is one hour, and after one hour or more has passed since the server 3 sent the token to the client terminal 2A1, the client terminal 2A2 sends the server 3, the processing after transmission of information indicating that user A2 has been verified is interrupted. Even if the invitation information is illegally leaked, when the expiration date of the basic information passes, the process of opening the shared account is stopped, so that the invitation information can be prevented from being illegally used.
If the shared account opening process is canceled for the above reasons, the display control information transmission unit 33 of the server 3 notifies the client terminals 2A1 and 2A2 that the shared account has been opened because a certain period of time has passed since the start of the shared account opening process. Display control information for displaying a screen indicating that the process has been canceled may be transmitted.

Next, when the display control information transmission unit 33 of the server 3 acquires the information indicating that the identity of the user A2 has been verified, which is received by the communication unit 3A, the client terminals 2A1 and 2A2 confirm approval of opening a shared account. Display control information for displaying the screen is transmitted (step ST5). The client terminal 2A1 displays the approval confirmation screen on the display unit 2D based on the display control information (step ST6-1), and the client terminal 2A2 displays the approval confirmation screen on the display unit 2D based on the display control information ( Step ST6-2).

FIG. 8 is a screen diagram showing an overview of approval processing using the approval confirmation screen 2D5 for opening a shared account. The approval confirmation screen display unit 26 of the client terminal 2A1 displays, for example, an approval confirmation screen 2D5 shown in FIG. 8 on the display unit 2D based on the display control information. The approval confirmation screen 2D5 includes information indicating that user A1 (Mr. A) is in the process of opening a shared account with user A2 (Mr. B). There is provided a column S6 with a description and a column S7 with a description of "to card issuance".

When the user A1 operates the "Cancel shared account opening" field S6 using the operation unit 2E, the approval confirmation screen display unit 26 displays the small screen P1 on the approval confirmation screen 2D5. The small screen P1 is a screen for confirming the cancellation of account opening, and is provided with an "execute" button S8 and a "cancel" button S9. Subsequently, when the user A1 operates the "execute" button S8 using the operation unit 2E, the approval confirmation result transmission unit 27 of the client terminal 2A1 transmits to the server 3 information indicating that the opening of the shared account is not approved (hereinafter " “Disapproval Information”). When the server 3 acquires the disapproval information from the approval confirmation result transmission unit 27 of the client terminal, it stops the process of opening the shared account, and the display control information transmission unit 33 of the server 3 sends the shared account display control information for displaying a screen indicating that the opening process of the has been canceled. The client terminal 2A1 that has acquired this display control information displays, for example, a screen 2D6 including the small screen P2 on the display section 2D. The small screen P2, as shown in FIG. 8, is a screen indicating that the opening of the shared account has been cancelled. On the other hand, the client terminal 2A2 that has acquired the above display control information also displays a screen indicating that the opening of the shared account has been canceled, for example, "Opening of the shared account has been canceled. Canceled by the other party." A screen (not shown) containing the message is displayed on the display unit 2D.

The user A1 uses the operation unit 2E to operate the "to card issuance" field S7 on the approval confirmation screen 2D5, or operates the "cancel" button S9 on the small screen P1 and "cancel card" on the approval confirmation screen 2D5. When the "to issuance" column S7 is operated, the approval confirmation result transmission unit 27 of the client terminal 2A1 transmits to the server 3 the approval information indicating that the user A1 has approved the opening of the shared account with the user A2 (step ST7- 1). Similarly, when user A2 approves opening a shared account with user A2, the approval confirmation result transmission unit 27 of client terminal 2A2 transmits approval information indicating that user A2 has approved opening a shared account with user A1 to the server. 3 (step ST7-2).

When the account opening section 34 of the server 3 acquires the approval information from both the client terminals 2A1 and 2A2, it opens a shared account shared by the users A1 and A2 (step ST8). For example, the account opening unit 34 uses user A1's identification information, user A2's identification information, the card number of the prepaid card B1 used by user A1 in the shared account, and user A2 in the shared account as the shared account information of users A1 and A2. and the identification information of the shared account are associated with each other and stored in the storage unit 3C.

In addition, the display control information transmitting unit 33 transmits to the client terminals 2A1 and 2A2 display control information for displaying a screen indicating that the shared account has been opened. In the client terminals 2A1 and 2A2, the approval confirmation screen display unit 26 displays a screen indicating that the shared account has been opened on the display unit 2D based on the display control information. FIG. 9 is a screen diagram showing completion of establishment of a shared account. For example, the client terminal 2A1 displays a screen 2D7 indicating that the shared account has been opened on the display section 2D. The screen 2D7 indicates to user A1 (Mr. A) that the shared account with user A2 (Mr. B) has been opened.

In the shared account opening process, the server 3 issues new prepaid cards to be used in the shared account to each of the users A1 and A2. For example, when the server 3 acquires the approval information, the server 3 inquires of the client terminal 2A1 and the client terminal 2A2 about the delivery destination information and PIN (Personal Identification Number) setting, and notifies the shipping date of the prepaid card.
The delivery destination information is information indicating the delivery destination of the prepaid card, and is the address of the user of the prepaid card. The PIN is a 4- to 8-digit number individually set by the user and associated with the prepaid card by the server 3 . The PIN is used for personal authentication within the client terminal or personal authentication when using a prepaid card at an ATM.
After prepaid cards B1 and B2 of the shared account are shipped to users A1 and A2, respectively, users A1 and A2 enter numbers identifying their respective prepaid cards using management applications executed by client terminals 2A1 and 2A2. This activates the prepaid card. The processing up to this point is the processing for issuing a prepaid card.

Also, the prepaid card used in the shared account is either a real card or a virtual card installed in the client terminal 2A1 or 2A2 as an application program, or both. If the prepaid card is a virtual card, the server 3 may activate the prepaid card immediately after obtaining approval information from both client terminals 2A1 and 2A2 and opening a shared account.

Further, the account opening unit 34 either performs both the processing of opening a shared account shared by users A1 and A2 and the processing of opening a personal account used only by user A2, or the processing of opening a personal account used only by user A1 and user A2. Only the process of opening a shared account to be shared and used may be performed.
For example, if user A2 has not opened a personal account when user A1 requests to open a shared account, the display control information transmitting unit 33, in addition to the display control information for displaying the approval confirmation screen, Display control information for displaying a screen for selecting whether or not to open a personal account together with a shared account is transmitted to the client terminal 2A2.
When the account opening unit 34 acquires the approval information from both the client terminal 2A1 and the client terminal 2A2, and acquires the selection result information indicating that the personal account is to be opened together with the shared account from the client terminal 2A2, the selection result information Accordingly, processing for opening a shared account shared by users A1 and A2 and processing for opening a personal account used only by user A2 are performed. In this case, user A2 is issued both a prepaid card B1 for shared account and a prepaid card for personal account used only by user A2.
Further, when the account opening unit 34 acquires the selection result information indicating that the personal account is not to be opened together with the shared account from the client terminal 2A2, the account opening unit 34 performs only the process of opening the shared account shared by the users A1 and A2. .

FIG. 10 is a screen diagram showing an example of use of the shared account, showing how the display screen of the display unit 2D of the client terminal 2A1 changes from the left screen to the right screen in order. It is assumed that user A1 has opened both a shared account and a personal account.
The screen 2D8 on the left is a commercial transaction history list screen relating to shared accounts shared by users A1 and A2. In the commercial transaction history list shown on the screen 2D8, information on the prepaid card used for settlement of the commercial transaction history is displayed for each commercial transaction history, and the commercial transaction history by the prepaid card of user A1 and the commercial transaction history by the prepaid card of user A2 are displayed. displayed in a distinguishable manner. For example, the screen 2D8 displays, for each commercial transaction history, an icon AP1 or AP2 representing the owner of the prepaid card, which is information on the owner of the prepaid card, as information of the prepaid card used for settlement of the commercial transaction history.

For example, an icon AP is displayed on the upper part of the screen 2D8. The icon AP indicates that the account whose commercial transaction history list is currently displayed is a shared account, and the users of the prepaid card for the shared account are user A1 indicated by icon AP1 and user A2 indicated by icon AP2. there is When the icon AP is operated using the operation unit 2E, an account switching screen P3 is displayed on the screen 2D8 as shown in FIG. An icon P31 representing a personal account and an icon P32 representing a shared account are displayed on the account switching screen P3.

For example, when the icon P31 indicating the personal account is operated using the operation unit 2E, as shown in FIG. 10, the screen is switched to the screen 2D9 showing the commercial transaction history list for the personal account. At this time, an icon AP1 is displayed, for example, at the top of the screen 2D9. Icon AP1 indicates that the account whose commercial transaction history list is currently displayed is the personal account of the owner (user A1) indicated by icon AP1.

So far, the case of opening shared accounts for users A1 and A2 has been shown, but the server 3 may open shared accounts for three or more users. In this case as well, it is assumed that the user who requests to open a shared account is a user who has registered for the prepaid card service provided by the information processing system 1 and whose identity has been verified.

Also, so far, the server 3 issues the prepaid cards B1 and B2 for the shared accounts of the users A1 and A2 after acquiring the approval information from both the client terminals 2A1 and 2A2. On the other hand, the server 3 may issue a prepaid card B1 for at least the shared account of the user A1 by obtaining a shared account opening request from the client terminal 2A1. Hereinafter, the information processing system 1 including the server 3 that performs such processing will be referred to as a "modification of the first embodiment".

The account opening unit 34 of the modification of the first embodiment acquires a request for opening a shared account for use by the users A1 and A2 from the client terminal 2A1 used by the user A1, and performs processing for opening a shared account. .
