Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, for example, when registering an account of an employee working at a store such as a convenience store, it is customary for a manager such as a store manager to approve and register that the employee is a legitimate employee working at the store. In such a case, the workload of a store manager or the like increases, and approval waiting is likely to occur. When approval waiting occurs, there is a risk that problems such as a delay in the start of work of the employee may occur.

[0006] This invention was made to solve the above-mentioned problems, and one of its objectives is to provide an account registration system and an account registration method that can reduce the effort required to register an account. [Means for solving the problem]

[0007] An account registration system according to one aspect of the present invention includes: an initial registration number transmission unit that transmits an initial registration number, which is different for each store and employee, and the system's telephone number to an employee terminal that has logged into the system; and an account registration unit that registers an employee's account on the employee terminal when the telephone number of a telephone terminal that has made a call to the system's telephone number matches the store telephone number registered in association with the employee's store identification information on the employee terminal, and the input number transmitted from the telephone terminal matches the initial registration number transmitted to the employee terminal.

[0008] Another aspect of the present invention relates to an account registration method performed by a processor, comprising the steps of: sending a unique initial registration number for each store and employee, as well as the system's telephone number, to an employee terminal logged into the system; and registering the employee's account on the employee terminal if the telephone number of a telephone terminal that has made a call to the system's telephone number matches the store telephone number registered in association with the employee's store identification information on the employee terminal, and the input number transmitted from the telephone terminal matches the initial registration number transmitted to the employee terminal.

[0009] According to these configurations, if the phone number of the phone terminal that made a call to the system's phone number notified to the employee terminal logged into the system matches the employee's store's phone number, and the input number transmitted from the phone terminal that made the call to the system's phone number matches the initial registration number notified to the employee terminal logged into the system, the system can authenticate that the employee logged into the system is a legitimate employee and register an account.

[0010] In the above embodiment, the system may further include an authentication code transmission unit that, upon receiving a login ID and password, transmits an authentication code to the employee's telephone number previously obtained from the employee terminal to which the login ID was assigned. The initial registration number transmission unit may transmit the initial registration number and the system's telephone number to the employee terminal if the input code received after the authentication code has been transmitted by the authentication code transmission unit matches the authentication code.

[0011] In this configuration, when a login request is received, an authentication code is sent from the employee's terminal to the employee's telephone number, which has been obtained in advance. When the authentication code is returned from the terminal that made the login request, the employee on that terminal is authenticated as a legitimate employee, and the initial registration number and the system's telephone number can be notified.

[0012] In the above embodiment, the device further includes: a receiving unit that receives information identifying the store, the employee's telephone number, and password from the employee terminal; a pre-authentication code transmitting unit that sends a pre-authentication code to the employee's telephone number received by the receiving unit; and a login ID transmitting unit that issues a login ID and sends it to the employee terminal if the input code received after the pre-authentication code has been sent by the pre-authentication code transmitting unit matches the pre-authentication code. The authentication code transmitting unit may also send an authentication code to the employee's telephone number if it receives the login ID and password after the login ID has been sent by the login ID transmitting unit.

[0013] According to this embodiment, when information necessary for account registration is received, a pre-authentication code is sent to the employee's phone number included in the received information. When the pre-authentication code is returned from the device that sent the information necessary for account registration, the employee on that device is authenticated as a legitimate employee, and the issued login ID is assigned. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide an account registration system and an account registration method that can reduce the labor required for account registration.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same elements are denoted by the same reference numerals, and redundant descriptions are omitted.

[0017] [Overview of Information Processing System] In this embodiment, a system is described, as an example, for registering employee accounts, including delivery personnel and store clerks, who deliver goods ordered by customers from physical stores to a location specified by the customer using a virtual store on a network. The stores in this embodiment include, for example, convenience stores that also provide delivery services, which sell goods in-store and also deliver ordered goods.

[0018] Referring to Figure 1, the configuration of an information processing system including an account registration system 1 according to an embodiment will be described. The information processing system includes, for example, an account registration system 1, an employee terminal 2 used by an employee, and a store telephone terminal 3 owned by a store.

[0019] The account registration system 1 consists of a server device that manages store information and employee information for each store, and performs processing to support employee account registration.

[0020] In this embodiment, for the sake of explanation, we will describe the case where the account registration system 1 is configured with a single server device. However, the server device that constitutes the account registration system 1 does not necessarily have to be a single device, and may be configured with multiple server devices depending on their functions and roles.

[0021] Employee terminal 2 may, for example, be a smartphone, but is not limited to this; any portable terminal with telephone functionality and a display will suffice.

[0022] As the store telephone terminal 3, for example, a push-button landline telephone can be used, but it is not limited to this, and a portable terminal with telephone functionality capable of transmitting tone signals may also be used.

[0023] The account registration system 1, employee terminal 2, and store telephone terminal 3 are configured to communicate via network N. Network N may be any of the following: the internet, LAN, dedicated line, telephone line, corporate network, mobile communication network, Bluetooth®, WiFi (Wireless Fidelity), other communication lines, or a combination thereof, and may be wired or wireless.

[0024] [Configuration of the account registration system] As shown in Figure 2, the account registration system 1 includes, for example, a processor 11, a storage device 12, and a communication unit 13.

[0025] The processor 11 is, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The processor 11 functions as a control unit that realizes various functions of the account registration system 1 by executing the program 121 stored in the storage device 12.

[0026] The storage device 12 is, for example, a computer-readable recording medium such as a disk drive or semiconductor memory. This storage device 12 stores, for example, a program 121 and data 122 used in the program 121.

[0027] Data 122 includes, for example, store information and employee information for each store's employees. Store information includes, for example, a store number to identify the store and the store's main telephone number. Employee information may also be included in the store information and managed together.

[0028] The communication unit 13 is an interface that connects to the network N and communicates with other devices and terminals on the network N.

[0029] [Employee terminal configuration] As shown in Figure 3, the employee terminal 2 includes, for example, a processor 21, a storage device 22, a communication unit 23, a display unit 24, and an input unit 25.

[0030] The processor 21 is, for example, a CPU or MPU. The processor 21 functions as a control unit that realizes various functions of the employee terminal 2 by executing the program 221 stored in the storage device 22.

[0031] The storage device 22 is, for example, a computer-readable recording medium such as a semiconductor memory or a disk drive. This storage device 22 stores, for example, the program 221 and the data used in the program 221.

[0032] Program 221 may include, for example, an employee application (hereinafter also referred to as the "employee app") to support employees' work. Employees can register an account, for example, using the screen displayed by running the employee app on employee terminal 2. Details of account registration will be described later.

[0033] Furthermore, the present invention can also be applied even if the employee application is not installed on the employee terminal 2. In this case, for example, it is preferable to support the employee's work by exchanging data between the employee terminal 2 and the account registration system 1 using a screen displayed on the employee terminal 2 when the employee terminal 2 connects to a designated site of the account registration system 1.

[0034] The communication unit 23 is an interface that connects to network N and communicates with other terminals and devices on network N.

[0035] The display unit 24 is, for example, a display with a touch panel, which displays images, screens, etc.

[0036] The input unit 25 is, for example, a touch panel, a pen tablet, a keyboard, or a microphone, and accepts input such as operating instructions from employees.

[0037] [Account Registration System Features] Referring to Figure 4, the functions realized by executing the program 121 of the account registration system 1 will be explained. The account registration system 1 has, functionally speaking, a receiving unit 111, a pre-authentication code transmission unit 112, a login ID transmission unit 113, an authentication code transmission unit 114, an initial registration number transmission unit 115, and an account registration unit 116. In this embodiment, it is assumed, for illustrative purposes, that the employee application is installed on the employee terminal 2.

[0038] The receiving unit 111 receives store identification information, employee telephone numbers, and employee passwords from the employee terminal 2. Store identification information, employee telephone numbers, and employee passwords are necessary for account registration and are preferably temporarily stored in the storage device 22 until account registration is complete. A detailed explanation will be provided with reference to Figure 5.

[0039] Figure 5 shows an example of an account creation screen 5a used by employees when they enter information that identifies the store, their phone number, and their password.

[0040] The account creation screen 5a includes, as an example, input fields 5b for entering the employee's name, 5c for entering the employee's phone number, 5d for entering the employee's employee number, and 5f for entering the employee's password. In the input field 5d for entering the employee's employee number, the employee may either directly enter their employee number, or they may press the "Barcode Reading" button 5e to activate the camera and scan the barcode on their name tag to enter their employee number. The employee number includes the store number, which is information that identifies the store, and a number that identifies the employee within that store. When the employee presses the "Create Account" button 5g, the information entered in each input field on the account creation screen 5a is sent to the account registration system 1.

[0041] Let's return to the explanation of Figure 4. The pre-authentication code sending unit 112 in Figure 4 sends an authentication code to the employee's phone number, which was received by the receiving unit 111. This authentication code will be called a pre-authentication code to distinguish it from the authentication code sent during login, which will be described later. The pre-authentication code can be sent to the employee's phone number using, for example, Short Message Service (SMS). This will be explained in detail with reference to Figure 6.

[0042] Figure 6 shows an example of a phone number authentication screen 6a used when an employee enters a pre-authentication code sent to their phone number. The phone number authentication screen 6a includes an input field 6b for entering the pre-authentication code, as an example. The employee enters the pre-authentication code sent to their phone number into this input field 6b. When the employee presses the "Authenticate" button 6c, the information entered in input field 6b is sent to the account registration system 1.

[0043] Let's return to the explanation of Figure 4. In Figure 4, the login ID transmission unit 113 issues an employee login ID and sends it to the employee terminal 2 if the input code received from the employee terminal 2 after the pre-authentication code transmission unit 112 has sent a pre-authentication code to the employee's telephone number matches the pre-authentication code. The employee login ID is stored in the storage device 22, linked to the employee number, employee name, employee telephone number, and employee password. A detailed explanation will be given with reference to Figure 7.

[0044] Figure 7 shows an example of a screen 7a used to notify employees of their login ID. This screen 7a is displayed as a pop-up above the phone number authentication screen 6a in Figure 6 when an employee presses the "Authenticate" button 6c on the phone number authentication screen 6a. This screen 7a has a field 7b that displays the new employee login ID assigned to the employee. When an employee presses the "Go to Login Screen" button 7c, they are redirected to the login screen described later.

[0045] Let's return to the explanation of Figure 4. The authentication code transmission unit 114 in Figure 4 sends an authentication code to the employee's phone number associated with the received login ID when it receives the login ID and password from the employee terminal 2 after the login ID transmission unit 113 has sent the login ID. The authentication code can be sent to the employee's phone number using, for example, the Short Message Service. This will be explained in detail with reference to Figures 8 and 9.

[0046] Figure 8 shows an example of a login screen 8a used by employees when they enter their login ID and password. The login screen 8a is a screen that requests the user to log in to the system. The login screen 8a includes, as an example, an input field 8b for entering the login ID and an input field 8c for entering the password. When an employee presses the "Login" button 8d, the login ID and password entered in each input field of the login screen 8a are sent to the account registration system 1.

[0047] Figure 9 shows an example of a two-factor authentication screen 9a used when an employee enters an authentication code sent to the employee's phone number after submitting their login ID and password. The two-factor authentication screen 9a includes an example input field 9b for entering the authentication code. The employee enters the authentication code sent to their phone number into this input field 9b. When the employee presses the "Authenticate" button 9c, the information entered in input field 9b is sent to the account registration system 1.

[0048] Returning to the explanation of Figure 4, the initial registration number transmission unit 115 in Figure 4 transmits the initial registration number and the telephone number of the account registration system 1 to the employee terminal 2 if the input code received from the employee terminal 2 after the authentication code transmission unit 114 has sent an authentication code to the employee's telephone number matches the authentication code. A different initial registration number is issued for each store and employee. The initial registration number is then stored in the storage device 22, linked to the store number and employee number.

[0049] The account registration unit 116 registers the employee's account on employee terminal 2 in the system if the phone number of the store's telephone terminal 3, which made a call to the telephone number of the account registration system 1, matches the telephone number registered in association with the store's store number, and the input number transmitted from the store's telephone terminal 3 matches the initial registration number displayed on the employee terminal 2. The telephone number of the store's main telephone is stored in the store information and linked to the store number. The input number transmitted from the store's telephone terminal 3 is transmitted as a tone signal. A detailed explanation will be given with reference to Figure 10.

[0050] Figure 10 shows an example of the initial registration screen 10a, which illustrates the procedure for registering an account using the telephone number and initial registration number of the account registration system 1. The initial registration screen 10a is provided with, as an example, a display field 10b for displaying step 1, a display field 10c for displaying step 2, and a display field 10d for displaying step 3.

[0051] Display field 10b shows "Make a call from the store's main phone number" as step 1, and "050-XXXX-XXXX" is displayed as the phone number to call. This phone number is the system phone number specified by account registration system 1. The employee uses the store's main phone number, store phone terminal 3, to call "050-XXXX-XXXX", which is the phone number for account registration system 1.

[0052] Display field 10c shows "Enter the initial registration number" as step 2, and "123456" is displayed as the initial registration number. The employee follows the voice guidance and presses the dial buttons on the store telephone terminal 3 to enter the initial registration number "123456". The entered initial registration number is converted into a tone signal by the store telephone terminal 3 and transmitted.

[0053] Display area 10d shows "Tap the 'Complete' button" as step 3, and a "Complete" button 10da is provided. Once the employee has finished entering the initial registration number, they press the "Complete" button 10da according to the voice guidance. This registers the employee's account on employee terminal 2 into the system. For example, the employee's account information will include the employee number, employee name, employee phone number, employee login ID, and employee password.

[0054] [Operation of the Information Processing System] Referring to Figures 11 and 12, an example of the process by which an employee registers an account in an information processing system will be described.

[0055] Figure 11 is a sequence chart showing an example of the actions an employee takes from operating employee terminal 2 to displaying the initial registration screen 10a in Figure 10.

[0056] First, employee terminal 2 displays the account creation screen 5a in Figure 5 according to the employee's operation, and accepts input into each input field and the press of the “Create Account” button 5g (step S101).

[0057] Next, the employee terminal 2, upon receiving the press of the “Create Account” button 5g, transmits the information entered on the account creation screen 5a to the account registration system 1 (step S102). The information transmitted to the account registration system 1 includes the employee number including the store number, the employee's telephone number, and the employee's password. It is preferable to temporarily store the employee number including the store number, the employee's telephone number, and the employee's password in the storage device 22 until the account is registered.

[0058] Next, the pre-authentication code transmission unit 112 of the account registration system 1 sends a pre-authentication code to the employee's telephone number received by the receiving unit 111 (step S103).

[0059] Next, employee terminal 2, which has received the pre-authentication code, displays the telephone number authentication screen 6a in Figure 6 according to the employee's operation, and accepts the input of the pre-authentication code and the pressing of the "Authenticate" button 6c (step S104).

[0060] Next, the employee terminal 2, having received the press of the “Authenticate” button 6c, sends the information entered on the telephone number authentication screen 6a to the account registration system 1 (step S105). The information sent to the account registration system 1 includes the pre-authentication code entered by the employee in the input field 6b.

[0061] Next, the login ID transmission unit 113 of the account registration system 1 determines whether the pre-authentication code sent to the employee terminal 2's telephone number in step S103 matches the pre-authentication code sent from the employee terminal 2 in step S105 (step S106). If this determination is NO (step S106; NO), the account registration system 1 notifies the employee terminal 2 that there is an error (step S107).

[0062] If the determination in step S106 above determines that the pre-authentication codes of both parties match (step S106; YES), the login ID transmission unit 113 of the account registration system 1 issues a login ID for the employee and sends it to the employee terminal 2 (step S108). The issued login ID is stored in the storage device 22, linked to the employee number, the employee's telephone number, and the employee's password.

[0063] Next, employee terminal 2, having received the employee's login ID, displays the login screen 8a in Figure 8 according to the employee's instructions, and accepts input into each input field and the press of the "Login" button 8d (step S109).

[0064] Next, the employee terminal 2, having received the press of the "Login" button 8d, sends the login ID and password entered on the login screen 8a to the account registration system 1 (step S110).

[0065] Next, the authentication code transmission unit 114 of the account registration system 1 sends an authentication code to the employee's phone number associated with the login ID sent from the employee terminal 2 in step S110 (step S111).

[0066] Next, the employee terminal 2, having received the authentication code, displays the two-factor authentication screen 9a in Figure 9 according to the employee's instructions, and accepts the input of the authentication code and the pressing of the "Authenticate" button 9c (step S112).

[0067] Next, the employee terminal 2, having received the press of the “Authenticate” button 9c, sends the information entered on the two-factor authentication screen 9a to the account registration system 1 (step S113). The information sent to the account registration system 1 includes the authentication code entered by the employee in input field 9b.

[0068] Next, the initial registration number transmission unit 115 of the account registration system 1 determines whether the authentication code sent to the employee terminal 2's telephone number in step S111 matches the authentication code sent from employee terminal 2 in step S113 (step S114). If this determination is NO (step S114; NO), the account registration system 1 notifies employee terminal 2 that there is an error (step S115).

[0069] If the determination in step S114 above determines that both authentication codes match (step S114; YES), the initial registration number transmission unit 115 of the account registration system 1 transmits the initial registration number and the telephone number of the account registration system 1 to the employee terminal 2 (step S116). The initial registration number transmitted to the employee terminal 2 is stored in the storage device 22, linked to the store number and employee number.

[0070] Next, employee terminal 2, which has received the initial registration number and the phone number of account registration system 1, displays the initial registration screen 10a in Figure 10 according to the employee's instructions (step S117).

[0071] Figure 12 is a sequence chart illustrating an example of the process from when an employee, referring to the initial registration screen 10a displayed on employee terminal 2, makes a call to the system using store telephone terminal 3 (the store's main telephone number), and is authenticated as a legitimate employee, until an account is registered.

[0072] First, the employee refers to the display field 10b of the initial registration screen 10a displayed on the employee terminal 2 in step S117 above, and then makes a call to the telephone number of the account registration system 1 from the store telephone terminal 3 (step S201).

[0073] Next, the employee follows the voice guidance of the caller, presses the dial buttons on the store's telephone terminal 3, and enters the initial registration number displayed in the display field 10c of the initial registration screen 10a (step S202).

[0074] Next, the store telephone terminal 3 into which the initial registration number has been entered transmits a tone signal corresponding to the initial registration number to the account registration system 1 (step S203).

[0075] Next, the account registration unit 116 of the account registration system 1 determines whether the telephone number of the store telephone terminal 3 that made a call to the telephone number of the account registration system 1 in step S201 matches the representative telephone number registered in association with the store number of the employee's store, and whether the initial registration number transmitted from the store telephone terminal 3 in step S203 matches the initial registration number displayed on the employee terminal 2 in step S117 (step S204). If this determination is NO (step S204; NO), the account registration system 1 notifies the employee terminal 2 that there is an error (step S205).

[0076] If the determination in step S204 above determines that both telephone numbers and initial registration numbers match (step S204; YES), the account registration unit 116 of the account registration system 1 registers the employee account of employee terminal 2 in the system (step S206). The registered employee account includes, for example, the employee number, employee name, employee telephone number, employee login ID, and employee password. Then, this operation ends.

[0077] [Effects of the Embodiment] As described above, according to the account registration system 1 of the embodiment, if the telephone number of the telephone terminal that made a call to the system's telephone number notified to the employee terminal 2 that logged into the system matches the main telephone number of the employee's store, and the input number transmitted from the telephone terminal that made the call to the system's telephone number matches the initial registration number notified to the employee terminal 2 that logged into the system, the employee on the logged-in employee terminal 2 is authenticated as a legitimate employee and an account can be registered.

[0078] Furthermore, upon receiving a login request, an authentication code is sent from the employee's terminal 2 to the employee's phone number, which has been obtained in advance. If the authentication code is returned from the terminal that made the login request, the employee on that terminal is authenticated as a legitimate employee, and the initial registration number and the system's phone number can be notified.

[0079] Furthermore, upon receiving the information required for account registration, a pre-authentication code can be sent to the employee's phone number included in the received information. If this pre-authentication code is returned from the device that sent the information, the employee on that device can be authenticated as a legitimate employee, and a login ID can be issued.

[0080] This allows employees who need to register an account to apply for registration using the store's main telephone number without requiring approval from the store manager or other supervisors.

[0081] Therefore, according to the account registration system 1 of this embodiment, it is possible to reduce the effort required for account registration while ensuring security.

[0082] It should be noted that the present invention is not limited to the embodiments described above, and can be implemented in various other forms without departing from the spirit of the invention. For this reason, the above embodiments are merely illustrative in all respects and should not be interpreted restrictively. For example, the order of each processing step described above can be arbitrarily changed or executed in parallel, as long as there is no inconsistency in the processing content.
