In the figure, 1 is an IC card which will be explained in detail later, and 3 is a magnetic card handling device comprising a card mechanism section 5 and a control section 4. This device is incorporated into, for example, an automated teller machine.

That is, when the card user inserts the magnetic card or IC card 1 into the card mechanism section 5, the card mechanism section 5 reads the data on the magnetic stripe. The read data is transmitted by the control unit 4 to a host device (not shown), where necessary processing is performed.

FIG. 2 is an external view of a card utilized under the present invention. In the figure, (,) is a conventional magnetic card, and a magnetic stripe 20 is provided on the surface of the magnetic card 2. As shown in FIG. In addition, FIG. 6(b) shows an IC card according to the present invention;
A magnetic strip drive 10 for storing card identification information and data is coated on the surface of the C card 1.
A semiconductor integrated circuit 15 is embedded in the inner surface.

FIG. 1 is a configuration diagram of an IC card showing an embodiment of the present invention.

In the figure, 0 is a magnetic stripe of the same standard as a conventional magnetic card, which is coated on the surface of an IC card 1 according to the present invention, and 11 is a magnetic stripe data sensor for writing and reading data to and from the magnetic stripe 10. /recording circuit; 12 is a central processing unit (CPU) that performs data control of the entire IC card;

13 is a memory (ROM) that stores processing programs and basic data for the CPU 12, and 14 is a memory (RAM) that stores normal data that is transferred to and from the IC card.

A magnetic stripe data detection section 11 detects data recorded on the magnetic stripe 10. The detected data is CP
It is transmitted to TJ12. If there is any registration instruction in the transmitted data, the CPU 12 processes this and then
The result is registered in the RAM 14. Furthermore, if there is any instruction to change in the transmitted data, the CPtjl, 2 processes the change of the data registered in the RAM 14 and records it on the magnetic stripe 10 via the recording unit 11 of the magnetic stripe data control circuit. do.

The flowchart in FIG. 3 shows the processing operation of the CPU 12 in the above IC card.

That is, when the CPU 12 detects an instruction to register the magnetic stripe data (step 301), C
The PU 12 processes the data on the magnetic stripe 10 (step 302) and registers the data in the RAM 14 inside the IC card 1 (step 303). On the other hand, when the CPU 12 detects a change instruction based on the data on the magnetic stripe 10 (step 304), the CPU 12 changes the data registered in the RAM 14 based on the specified data on the magnetic stripe 10, and transfers the data to the magnetic stripe 10. (Step 305).

The fourth is a flowchart of processing operations in the magnetic card handling device 3 of the present invention.

This will be explained below with reference to FIG.

First, when the user inserts the card 1, the card mechanism section 4 detects this (step 401) and reads the data on the magnetic stripe (step 402).

Next, as mentioned above, since identification information indicating that it is an IC card is written on the magnetic stripe in advance,
Based on this identification code, the control unit 4 determines the type of card (step 403).

If it is a magnetic card, a host device (not shown) processes the read data (step 410) and records the result on the magnetic stripe 20 (step 411).

On the other hand, if it is an RC card with a magnetic stripe 10 attached, the control unit 5 connects the CPU 12 via the magnetic stripe 10.
The data on the RAM 1.4 is transferred to the magnetic drives 1 to 10 (step 404).

As a result, the control unit 4 reads the data recorded on the RAM+4 via the magnetic stripe 10 (step 405), and this data is transmitted to a host device (not shown) and processed (step 406).

The results processed by the host device are recorded from the control unit 4 to the RAM 14 by the CPtJ2 via the magnetic stripe 10 (Stella 407).

Finally, the control unit 4 checks the processing status in step 40.
9), the IC card is ejected from the card mechanism section 5 and the entire process is completed (step 409).

In this way, the IC card can be processed by a conventional magnetic card handling device using the magnetic stripe 10 provided on the IC card as an intermediary.
