CONSTITUTION:When an IC card 1 is inserted into a card recording reader, an instruction for reading out the contents of a storage part 10 is transmitted to a receiving means 4 by an optical signal. A transmitting/receiving part 12 which has received this signal transfers a read-out instruction of a data to an operation processing part 9, reads out a necessary data from the storage part 10 and sends it to the transmitting/ receiving part 12, and transmits it to the card recording reader. When this optical signal is received, an automatic transaction device collates it with a password and executes a payment operation, and transmits transaction details, etc. to the IC card 1. The IC card 1 which has received said details writes them in the storage part 10, and sends back recording end information. The card recording reader which has received said information sends a display instruction of the latest transaction details, and the IC card 1 displays said details. When a customer depresses an operation switch 7 and an operation switch 8, the past and the latest transaction details can be displayed, respectively.

By transmitting a target signal, a transaction statement recording command and transaction statement data are sent.

The IC card 1 receives the transaction statement recording command and the transaction statement data by the receiving means 4, and writes the transaction statement data into the storage section 10 as the latest data via the reception signal conversion circuit 17, the transmitting/receiving section 12, and the arithmetic processing section 9. Write and memorize the address. When the storage is completed, the IC card 1 transmits the recording completion information of the transaction details data by the same means as the transmission of the personal identification data, that is, via the transmitting/receiving section 12, the driving circuit 18, and the transmitting means 6. It is returned to the receiving section 22 of the card recording/reading device 20.

The recording end information is sent to the reception signal converter 2 by the receiver 22.

When the IC card 1 receives the command to display the transaction details by the receiving means 4 via the reception signal converter 17 and the transmitter/receiver 12, the transaction details are displayed from the address of the storage section 10 storing the latest data of the transaction details. The arithmetic processing unit 9 reads the latest data and transfers it to the operation display control unit 11. The operation display control unit 11 sends the latest data of the transaction details to the drive circuit 1.
It is displayed on the display unit 3 via 9.

When this display is performed, the IC card 1 transmits display end information via the transmitting/receiving section 12 to the receiving section 22 of the card recording/reading device 20 via the drive circuit 18 and the transmitting means 5. The receiving section 22 transmits the display end information to the processing storage section 21 via the reception signal conversion circuit 26, and the processing storage section 21 reports the display end information to the automatic transaction device 9 control section. Upon receiving the display end information, the automatic transaction device instructs the control unit to return the PXC card 1 and pays out cash.

Then, the customer receives the cash and IC card 1, and
The latest transaction details are confirmed by looking at the display section 3 of the card 1.

If the customer wishes to know the past transaction details, the past transaction details can be displayed on the display section 3 by pressing the operation switch 7 once as shown in the flowchart of FIG. Each time 8 is pressed, the display on the display section 3 can be changed step by step in the direction of displaying new transaction details.
