Abstract

PURPOSE:To simplify the operation of transaction processing by storing the information showing a transaction enable period despite no input of an identification number to an IC card and discriminating said stored information to carry out the transaction. CONSTITUTION:The information showing a transaction enable period is stored even though no identification number is supplied to an IC card. This information stored in the IC card is read by a card reader 3. A CPU 1 checks whether the date received from a date data generating means is kept or not within the period read by the card reader 3. Then the CPU 1 requests the input of an identification number as long as said date is out of the prescribed period despite no input of the identification number. While no request is given for the input of the identification number if the date is within said period despite no input of the identification number. Then the transaction processing is carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a transaction processing device, and particularly to a transaction processing device that performs sales registration processing using an IC card.

[Prior Art] Recently, transaction processing devices that process transactions using IC cards have been put into practical use. This IC card has approximately the same size and shape as a magnetic card such as a cash card or credit card, and includes an integrated circuit including at least a CPU and a memory. These IC cards are extremely convenient and will continue to be used in the future, as they allow transactions to be made without having to carry cash and are being developed so that one card can be used for a variety of transactions. It is believed that demand will continue to increase.

By the way, in conventional transaction processing devices that perform transactions using IC cards, the transaction is processed only after the customer enters a personal identification number to confirm the customer's identity.

[M points to be solved by the invention] However, since the input operation of the PIN number and the confirmation process based on the input PIN number take a considerable amount of time, when a large number of customers visit the store, it is difficult to The problem was that customers were forced to wait for a long time until the process was completed, resulting in a lack of customer service.

Furthermore, it is troublesome for customers who frequently use the store to have to enter their password every time they use the store.

Therefore, this invention was made to solve the above-mentioned problems, and allows the customer to set information on the IC card indicating the deadline for transactions without manually inputting the PIN number. It is an object of the present invention to provide a transaction processing device which allows transactions to be processed without inputting a personal identification number when the IC card is used in a computer.

[Means for Solving the Problems] The transaction processing device of the present invention includes an IC that records information indicating a deadline for transaction processing without inputting a personal identification number.
A card, a reading means for reading recorded contents from the IC card, a date data generating means for generating date data indicating the current date, and a date given by the date data generating means in response to reading by the reading means. A determination means for determining whether the read deadline is within the above-mentioned deadline, and a determination means that determines that the transaction is outside the deadline for transactions without inputting the PIN number. , and if the identification means determines that the transaction is within the deadline for transactions without inputting the PIN, the transaction will be processed without requiring the manual input of the PIN. and a control means for controlling.

[Operations] In this invention, information indicating a deadline for transaction processing without inputting a PIN number is stored in the IC card,
It is determined whether or not the date given by the date data generation means is within the time limit read by the reading means, and if it is outside the time limit in which the transaction can be performed without the manual input of the PIN number,
If the input of the PIN number is requested and the transaction is possible even if the PIN number is not input within the time limit, the transaction is processed without requiring the input of the PIN number.

[Embodiment] FIG. 3 is a schematic block diagram showing the electrical configuration of a transaction processing device to which an embodiment of the present invention is applied. In Figure 3, the CPU 1 includes a keyboard 2, a card reader 3, and a
IN pad 4, timer 5, display 6, printer 7 and RO
M8, RAM 9, and transmission processing section 10 are connected. The keyboard 2 includes keys for instructing business contents such as sales registration processing and inquiry processing, and a numeric keypad for inputting product food and price data. The card reader 3 reads recorded contents from an IC card. The PIN pad 4 is used by the customer to input a personal identification number. timer 5
In this embodiment, the display device 6 used for transactions displays operation guide characters, amount data inputted from the keyboard 2, and the like.

The printer 7 is used to issue slips and the like showing details of transactions. The ROM 8 stores a CPUI operating program based on a flowchart as shown in FIG. 1, which will be explained later. The RAM 9 includes an area for storing transaction data input from the keyboard 2, recorded contents read by the card reader 3, and the like. The transmission processing unit 10 mediates data transmission between the CPUI and a host computer (not shown).

FIG. 4 is a schematic block diagram showing the electrical configuration of the IC card used in the present invention. This IC card can store a deadline (hereinafter referred to as a PIN entry-free deadline) during which transactions can be made without inputting a PIN number.

In Figure 4, the IC card has a CPU II and a CPU
Memory connected to PUII 12. A keyboard 13 and a display 14 are built-in. Including Memoria. The keyboard 13 is used to input the deadline for not requiring input of a password. The display device 14 displays information such as a password no longer required input period and other data when an input instruction is received from the keyboard 13.

FIG. 5 is an illustrative diagram showing the storage area of the memory 12 of the IC card shown in FIG. In Figure 5, area 12
1 is an area for storing a time limit for not requiring input of a password. Area 122 is an area for storing a customer identification code for identifying a customer.

Area 123 is an area for storing a function for determining one function value based on the password data. Area 124 is the X of the function Y-F (X) shown in area 123.
This is an area for storing the value of the function value Y1 obtained when the customer's PIN number is substituted into .

Here, the function stored in the area 123 may be a simple one such as calculating the sum of each digit of the PIN number, but if the PIN number X is given, 1
If one function value is obtained and, conversely, a function value Y is given, it is preferable to use one that allows a large number of X to be obtained. In this way, even if the function stored in area 123 and the function value stored in area 124 are read out by another person, it is difficult to decipher the password.

FIG. 2 is a flowchart for explaining the operation of the IC card when storing the deadline for not requiring input of a password in the area 121 shown in FIG. Next, the operation of the IC card will be explained in detail with reference to FIGS. 2 to 5.

For example, when a customer goes to a supermarket or the like that he or she often uses to make a gift, a time limit for not requiring manual input of a PIN number is stored in the IC card so that the input of the PIN number is not required on that day. In order to memorize this password-free expiration date, the customer first selects one of the keys provided on the keyboard 13.
Press the function key that indicates the appropriate storage mode.

Next, the user enters the password using the keyboard 13.

The CPU II stores the input PIN data in area 123.
Substitute into the function stored in and calculate the function value. Subsequently, it is determined whether the calculated function value matches the function value Y1 stored in the area 124. If the function values do not match, it is assumed that the PIN was not entered correctly, and the user is allowed to enter the PIN again. However, if the function values match, the user must then enter the period when the PIN is not required. To give permission.

In response to the customer inputting the password-unnecessary deadline from the keyboard 13, the CPU II writes the entered password-unnecessary deadline in the area 121, and ends the operation.

FIG. 1 is a flow diagram for explaining the operation of the transaction processing apparatus of the present invention shown in FIG. Next, the operation of the transaction processing device will be explained in detail with reference to FIGS. 1 to 5.

Customers walk around the store, holding the products they wish to purchase,
Go to the checkout counter and present your IC card to the staff. The clerk operates the keyboard 2 to instruct sales registration, and then instructs that the transaction is to be made using an IC card. If the transaction is not a card transaction, the CPU 1 performs other processing such as cash transaction, but if a card transaction is instructed, the CPU 1 displays on the display 6 that an IC card should be inserted. When the clerk inserts the IC card handed over by the customer into the card reader 3, the card reader 3 reads card data from the IC card and provides it to the CPUI. C
The PUI determines whether or not the password manual input period is within the period based on the data indicating the period for which the password input is not required and included in the given card data and the date data provided by the timer 5.

If the PIN entry-free period is still within the PIN entry-free period, sales processing will be performed without requesting the PIN entry; however, if the PIN-input-unnecessary period has passed, the PIN number should be entered on the display 6. Display the following information.

If the period for not requiring PIN entry has passed, the customer must
Enter the password using the IN pad 4.

Accordingly, the CPU calculates a function value using the function stored in area 123 based on the input PIN data, and determines whether the calculated function value matches the function value Y1 stored in area 124. Determine whether or not. If the function values do not match, the PIN was not entered correctly, so error handling is performed; however, if the function values match, it is determined that the PIN was entered correctly manually, and sales processing is then performed. Let's do it.

In this way, customers can freely set the period when they do not need to enter their PIN number, so if they do not need to enter their PIN number just on the day they go shopping at a supermarket, they can easily make transactions even if their IC card is stolen later. Since it is necessary to enter a password when doing so, there is little risk that the IC card will be misused.

[Effects of the Invention] As described above, according to the present invention, the deadline for not requiring input of a PIN number is stored in the IC card, and the date generated by the kiss data generation means is input when the PIN code is read from the IC card. Since the transaction process is performed without requiring the input of a PIN number by determining whether or not it is within the no-necessity period, the time required for transaction processing within the PIN no-input period is shortened.
