[0020]
Use mode # 1 is convenient when the user (customer) inserts an IC card and uses it by fixing it to a cafeteria or restaurant. In FIG. A card is inserted, and the processing contents and the like are displayed on the display unit 2. In this example, the example used in the integrated case shown in FIG. 5 is described. However, if the aesthetics and functions are ignored, it can be installed in the configuration shown in FIG. The usage pattern # 1 is a normal fixed amount subtraction type settlement apparatus, which subtracts a fixed amount set in advance from the server every time a user's IC card is inserted and releases the IC card. An ID for identifying an IC card is stored together with the date and time in a built-in memory unit, and by performing a necessary operation, a transaction log can be issued to the printer or a journal can be output. Pre-setting can be done by connecting to a host computer in the office or manually by entering the installation location. By attaching the receipt issuing unit 50, a receipt can be issued and delivered on the spot at the time of use. FIG. 7 shows an example of a system using the fixed amount subtraction method. When an IC card is inserted, the server checks whether or not the IC card with the corresponding ID can be used. Will be sent. In a simple system, only information such as how many sales per day is required, and how much the total amount is, is necessary. The total sales per day can be calculated simply by printing on receipt paper or writing data on a log IC card. It is enough. Normally, in the case of a fixed amount subtraction type checkout apparatus, it takes time to enter a personal identification number, and a customer can be queued. However, since the amount to be subtracted is small, input verification of the personal identification number is omitted.
[0021]
Usage mode # 2 is a subordinate connection as a child terminal of the POS cash register terminal. The usage mode # 1 is used to subtract the total amount settled at the POS cash register from the inserted IC card. And different. After subtracting, the IC card terminal device notifies the POS terminal that the subtraction has been made, so that the POS terminal side will withdraw the specified amount as the same non-cash processing as when paid with a gift certificate or check. Accounting can be done. The transaction log stored in the memory unit and described in the usage form # 1 can be performed. In this case, the receipt is normally issued on the POS terminal side.
[0022]
Usage mode # 3 is a case where the accounting calculation is separately completed and the settlement amount is paid by the IC card. When the IC card is inserted into the IC card terminal device, the billing amount is displayed, and the user enters the password and confirms it, and then it is withdrawn (the password may not be confirmed). Also in this case, it is possible to launch a transaction log or the like stored in the memory unit and described in the usage mode # 1. If a receipt printer is attached, it is possible to print on the receipt at the same time as payment, and then perform a split payment process.
[0023]
Usage type # 4 is a case where accounting calculation and payment are completed only by the IC terminal device. First, the store clerk inputs the usage statement amount into the input pad 10, and when the total amount is printed, the IC card is deposited from the customer and inserted into the reader / writer 20, the input pad 10 is handed over to the user and the password is entered. This is the case. In this case, the receipt issuing unit 50 and the journal printer 40 are usually connected, and the receipt is distributed to the customer. Thereafter, a split-out process can be performed.
[0024]
Usage mode # 5 is a case where the IC terminal device is also used as an order input terminal, and the store clerk carries the input pad 10 and the reader / writer 20 together and inputs the menu of the customer in front of the customer. The customer's IC card is deposited and subtracted in front of the customer.
[0025]
In the above usage mode, as shown in the state transition diagram of FIG. 6, the IC card terminal device waits for insertion of a master card when the power is first turned on, and various settings are made when the master card is inserted in this state. Processing begins. Before receiving the start command from an external POS terminal or checkout machine, download the IC card usage data (white data (usable card data), black data (unusable card data)) from the server. In addition to receiving and setting, the current time is set from the host (server), and a necessary status notification command is received from the external settlement machine or POS and sent to the host. Next, when the operation start command or manual operation mode is set, the card waits after receiving the IC card reception command from the host side, and the card check is performed when the IC card is inserted. The command is ejected to enter a command waiting state (idle state). If OK, the subtraction command is received and the IC card data is rewritten. Then, the IC card is returned by the card return command, and the idle state is entered. If a forced return command is received before the subtraction process, the IC card is returned to return to the idle state. In the idle state, the operation is returned to the operation start state by an end command from the host or a manual end operation.
[0026]
Next, in the present invention, a fixed amount subtraction method, a POS terminal method, a settlement machine terminal method, an IC card dedicated register method, and a RAS are performed depending on the transaction in which the amount of money to be updated is input mainly to the IC card. Five types of functions are available. The fixed amount subtraction method is to subtract the amount set in the device every time a transaction is made, and as a setting method, it is downloaded from a host controller using a LAN line, or is set by a price setting card or a numeric keypad of the input means 11 Is also possible. For example, in the case of a student cafeteria or employee cafeteria, the fixed amount subtraction method is 400 yen for A lunch, 550 yen for B lunch, 620 yen for C lunch, and so on. Suitable for various specifications. In addition, the POS terminal method subtracts the amount of money transmitted from the POS cash register, and either RS232 or RS422 / 485 can be selected for connection, and the calculation of purchased items is completed at a cash register such as a supermarket. It is suitable for the specification that the amount requested at the time is withdrawn from the IC card. In the same manner, the settlement machine terminal system subtracts the amount transmitted from the settlement machine. The IC card dedicated register system uses an IC card terminal device as a register, and subtracts the amount of money input from the numeric keypad of the input means 11, and a store clerk or the like carries the input pad 10 or the input pad 10 and the reader / writer 20 It is suitable for specifications that carry the department and move inside the store. The RAS function is to perform device setting and operation check of the device.
[0027]
FIG. 7 shows the connection relationship between the IC card terminal device, server, and printer in the flat-rate subtraction method. The server manages transaction logs, blacklists, etc., and communicates via LAN or modem. The printer prints the journal. FIG. 8 shows the information exchange relationship between the manager (IC card terminal device) and the customer (user). When the customer inserts his / her personal card into the card insertion slot 21 of the reader / writer 20 of the portable unit, the reader / writer 20 subtracts a fixed amount set in advance by the server or RAS function if the personal card is valid, The balance after the subtraction is written on the personal card, and after confirming the subtraction from the card, the apparatus creates a transaction log and discharges the personal card from the card insertion slot 21. Thereafter, the customer removes the personal card, and after confirming the removal of the card, the apparatus saves the transaction log.
[0028]
FIG. 9 shows the connection relationship between the IC card terminal device in the POS cash register terminal system, the server, the printer, and the POS cash register. Information exchange between the administrator and the customer is as shown in FIG. . The POS cash register is a device used when a terminal device is used as a POS cash register terminal by a communication function. That is, when a customer inserts a personal card into the card insertion slot 21 of the reader / writer 20 of the portable unit, if the personal card is valid, the customer waits for a deduction amount from the POS cash register, and the administrator inputs the money amount to the POS cash register. Thus, the balance after subtraction is written on the personal card and discharged. When the customer removes the personal card, the transaction log is saved after the card removal confirmation.
[0029]
FIG. 11 shows a connection relationship between the IC card terminal device and the payment machine, printer, and server in the payment machine terminal system, and FIG. 12 shows the exchange of information between the customer and the administrator. . In other words, when a customer inserts a personal card into the card insertion slot 21 of the reader / writer 20 of the portable unit, if the personal card is valid, it waits for the subtraction amount input from the settlement machine, and the administrator inputs the amount to the settlement machine. By doing so, the balance after subtraction is written on the personal card and discharged. When the customer removes the personal card, the transaction log is saved after the card removal confirmation.
[0030]
FIG. 13 shows the connection relationship between the IC card terminal device, server and printer in the IC card dedicated register system, and FIG. 14 shows the exchange of information between the customer and the manager. That is, the customer inserts a personal card into the card insertion slot 21 of the reader / writer 20 of the portable unit, inputs a personal identification number from the input means 11 of the input pad 10 and then inputs an amount, and the balance after subtraction of the input amount Is written on a personal card, and a transaction log is created and discharged. When the customer removes the personal card, the transaction log is saved after confirming that the card has been removed, but in the case of split payment processing, the input of the next card is requested and the initial state is restored.
In the case of the RAS function for device setting and operation check of the apparatus, it is only necessary to connect to a server and a printer as shown in FIG.
[0031]
In the present invention, it is possible to pay by split account. As a split account method, 1) each person enters his / her account into the terminal and pays electronic money, and 2) an amount obtained by dividing the balance of payment by the number of people. There are an equal number of people system that pays electronic money calculated by a terminal, and 3) a combined percentage account system that is a combination of the above-mentioned self-payment amount reporting system and the equal number of people system. Since the mobile unit is handed over to the customer after the billing amount is fixed, the billing amount cannot be changed with the mobile unit removed so that the billing amount does not change due to a customer operation error or the like.
[0032]
The split payment process is performed according to the flowchart shown in FIG. 16, and when the total payment amount is confirmed (step S1) and the split key of the input means 11 is pressed (step S2), each person's own amount declaration system, equal number of persons split, and discount cancellation are cancelled. The selection mode is set (step S3). When each mode is selected with the input means 11 in this mode selection, an IC card is inserted (step S10), an amount is entered (step S11), and a personal identification number is entered (step S12), followed by an execution key. When is pressed, the data is updated (step S14), and if there is a balance, the process returns to step S3 to repeat the above operation (step S15). If there is no balance remaining, the payment process ends. In addition, when the uniform number system is selected in the mode selection, first, the number of persons is input (step S20), the amount is displayed on the display unit 12 (step S21), the IC card is inserted (step S22), and the code is entered. When a number is input (step S23) and then the execution key is pressed, the data is updated (step S25), and the operations after step S21 are repeated for the equal number of people (step S26). Further, when the cancellation is selected in the mode selection, the IC card is first inserted (step S30), the balance is displayed on the display unit 12 (step S31), the password is input (step S32), and then executed. When the key is pressed (step S33), the data is updated (step S34), and the cancellation process ends.
[0033]
The present invention has an IC card terminal device state monitoring function, an information communication function to the IC card terminal device, a data receiving function from the IC card terminal device, and a security function during operation. That is, when no IC card terminal device that is permitted to be connected to the controller (server) is in a connected state, the security function requests a system password at the time of activation. This is for the purpose of protecting the security function from being incorporated into the operation analysis or unauthorized processing when the security function is not used at a normal location, for example, when copying only the controller software or taking out the device. When even one IC card terminal device that is permitted is connected, the operation is started with priority on the convenience of the user. The IC card terminal device is equipped with a battery for guaranteeing a portable function and a transaction at the time of a power failure, and the power source is energized for 24 hours in order to perform charging / refresh recharging. When log communication is performed on the LAN, a connection for socket communication is established from the IC card terminal device because the IC card terminal device is positioned as a client and the controller as a server.
[0034]
On the other hand, as for security at the time of communication with the IC card terminal device, when receiving a message from the terminal device, it is necessary to mutually confirm whether the other party can receive or send the message. FIG. 17 shows a security function at the time of such communication. Random numbers are generated from each other, the content encrypted with the specific key 1 is transmitted, the received one is decrypted with the specific key 1, and encrypted with the specific key 2. A reply is made and decrypted with the specific key 2 to confirm whether or not they match. Thereby, it is possible to prevent “spoofing” of the server as viewed from the IC card terminal device and “spoofing” of the IC card terminal device from the server. The specific keys 1 and 2 at this time are preset.
[0035]
FIGS. 18 and 19 show the details according to the classification of the IC card terminal device and the upper server. After the connection process to the upper server (step S40), it is determined whether or not it is OK (step S41). Generates a random number A (step S42), encrypts the random number A with the key 1 to obtain an encrypted random number A (step S43), and transmits the encrypted random number A to the upper server (step S44). After receiving the encrypted random number A (step S45), the host server decrypts the encrypted random number A with the key 1 to obtain the random number A (step S46), encrypts the random number A with the key 2 and obtains the encrypted random number B. Obtain (step S47). The host server transmits the encrypted random number B to the IC card terminal device (step S48). After receiving the encrypted random number B (step S50), the IC card terminal device decrypts the encrypted random number B with the key 2 (step S50). S51), it is determined whether or not it matches the original random number A transmitted encrypted (step S52). If they do not match, it is NG and line disconnection processing is performed (step S53). On the other hand, if they coincide with each other in step S52, a transmission request is output to the upper server (step S54), whereby the upper server generates a random number C (step S55). Is converted into an encrypted random number C (step S56), and the encrypted random number C is transmitted to the IC card terminal device (step S57). After receiving the encrypted random number C (step S60), the IC card terminal device decrypts the encrypted random number C with the key 1 to obtain the random number C (step S61). The random number C is encrypted with the key 2 and encrypted. A random number D is obtained (step S62). Then, the IC card terminal device transmits the encrypted random number D to the upper server (step S63), and when the upper server receives the encrypted random number D (step S64), the encrypted random number D is decrypted with the key 2 ( In step S65, it is determined whether or not the decrypted data matches the transmitted random number C (step S66). If they match, the operation of the IC card terminal device is started (step S67). If they do not match, line disconnection processing is executed (step S68).
[0036]
FIG. 20 shows the setting operation at the time of start. It is determined whether or not the timer is set in the standby mode (step S70) (step S71). Is determined (step S72), and if it is the start specified time, it is activated (step S73) and the normal operation is performed (step S74). Then, it stops when the end designated time is reached (step S75). If the timer is not set in step S71 and if it is not the start designated time in step S72, it is determined whether or not a start command from the upper command is received (step S80), and the start command is received. It is sometimes started (step S81) and normal operation is performed (step S82). Then, normal operation is executed until an end command is received from the upper command (step S83). If the activation command from the host command is not received in step S80, it is determined whether or not the activation is based on the store card (step S84). If the activation is based on the store card, the activation is activated (step S85) and normal operation is performed. Continue until the end of the store card (step S87). On the other hand, if the store card is not activated in step S84, the process returns to step S70.
