Abstract

(57) [Abstract] [PROBLEMS] To provide a highly secure card system that does not require operation time when using the card. SOLUTION: When a card user inputs transaction data such as a personal identification number from a card input means 16 before using a cash dispenser 30, the input data is the card RA.
It is stored in M13. When the card 10 is inserted into the card reader 20, the data of the card RAM 13 is transmitted to the card reader 20 via the card output terminal 15 and the card reader input terminal 25, and after confirming the data, the transaction processing is performed by the cash dispenser. When the transaction process ends and a predetermined time has elapsed after the transaction data is input, the transaction data stored in the RAM 13 is erased by the erasing means 17. As a result, the data input operation time can be shortened and the safety against the loss or theft of the card is enhanced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card system used in a cash dispenser or the like.

[0002]

2. Description of the Related Art Conventionally, for example, when using a cash card of a bank to refund money, insert the card into a cash dispenser, and then while watching the screen, "Refund", "PIN", "Amount" Then, the user entered the necessary data (transaction data) in the order of “confirmation”.

Further, a card in which a personal identification number or the like is registered in advance and does not need to be input at the time of use, can be used by a person other than the owner of the card.

[0004]

The conventional card system has the following problems. When a card dispenser is used, the above-mentioned series of operations are required, so that the device usage time per person becomes long, and when there are many users, it takes time to wait in order.

A card that does not require a personal identification number may be misused when it is lost or stolen. The object of the present invention is to reduce the operation time when using the card,
It is to make the card system highly secure.

[0006]

A card system according to the present invention is a card system comprising a card and a card reader for reading the data of the card, and an input means for inputting transaction data to the card and storing the transaction data. A card reader having a storage means, an erasing means for erasing the input transaction data, a clocking means for measuring the elapsed time from the time of inputting the transaction data, and a card reader having a reading means for reading the transaction data from the card. The transaction data is input to and stored in the card before the card is inserted into the card reader, and the input data is erased by the erasing means when a predetermined time has elapsed since the transaction data was input to the card.

As a result, the transaction data that has already been input and stored when the card is used is read by the card reader, so that the operation time when using the card is not required. Moreover, since the transaction data is erased after the lapse of a predetermined time, the security of the card can be surely maintained.

FIG. 1 is a configuration block diagram showing an embodiment of the present invention. This system includes a card 10, a card reader 20, and a cash dispenser 30. The card 10 includes a card CPU 11 that controls the functions of the card, a card ROM 12 that stores a card control program, and a card RA that stores data.
M13, input means 16 for inputting transaction data such as personal identification number and refund, erasing means 1 for erasing input data
7 and the card CPU 11 via the card I / O 14
The card output terminal 15 connected to.

The card reader 20 includes a card reader CPU 21 for controlling the card reader 20, a card reader ROM 22 for storing a card reader control program, a card reader RAM 23 for storing data, and a card reader CPU 21 via a card reader I / O 24. The card reader input terminal 25 connected to. Further, the card reader CPU 21 is connected to the cash dispenser 30 via the data transmission means 26.

The operation of the card system having this configuration is as follows. Before inserting the card 10 into the card reader 20, the card user inputs transaction data such as a personal identification number of the card or a money refund before inputting the card 10 into the card reader 20, for example, during a waiting time for using the cash dispenser. The input means 16 may be, for example, touch keys or push buttons used in a card calculator and a liquid crystal panel for displaying data. The input data is RA by the card CPU 11.
It is stored in M13.

When the card 10 is inserted into the card reader 20, the card output terminal 15 changes to the card reader input terminal 2
Data is read via 5. Card reader CPU
After confirming the data of the card 10, the card 21 sends the data to the cash dispenser 30 via the data transmission means 26, and the cash dispenser 30 performs a predetermined process such as money refund.

By the above operation, the user does not have to input transaction data such as a personal identification number into the cash dispenser, so that the operation time is not required when using the card. In the above operation process, the card 10 to the card reader 2
0 indicates that the data has been correctly transmitted to the CPU 11 of the card 10 by, for example, a confirmation signal from the card reader 20.
Can be detected. Then, when the confirmation signal is detected, if the erasing means 17 erases the data input to the card by the command of the CPU 11, the data such as the personal identification number is erased immediately after the card is used, so that the card is safe. Can be kept.

Alternatively, the input data may be erased by the erasing means 17 when a predetermined time has elapsed since the data was input by the clocking means in the card.

[0014]

According to the present invention, transaction data such as a personal identification number is stored in a card before the card is inserted into the card reader, and this data is read when the card is inserted. Since the operation time of is not required, the waiting time can be shortened. Moreover, since the input data is erased after a predetermined time has passed since the data was input to the card, the safety of the card is enhanced.
