Abstract

PURPOSE:To detect an error insertion of an IC card to positively prevent the breakage of the IC card and a circuit by a method wherein a conductor is provided within the IC card, a signal is transmitted to the conductor part by an IC card reader/writer, and whether the conductor part is electrically conducted is detected. CONSTITUTION:When an IC card 1 provided with a conductor 2 therein is inserted to an insertion part 3 of an IC card reader/writer, the insertion part 3 informs a detection part 4 of the setting of the IC card 1. The detection part 4 passes an electric current to the conductor part 2 of the IC card 1, detects whether the conductor part 2 is electrically conducted, and informs a control part 5 of the detection result. The control part 5 judges whether the insertion state of the IC card 1 is normal. At the time of judging the normal state, an access to the IC card is started, and data is read/written on the IC card 1. In this manner, the breakage of the IC card 1 and a circuit caused by the contact shift of the IC card 1 is prevented.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card and an IC card read/write device, and more particularly to prevention of incorrect insertion of an IC card into an IC card read/write device.

0002

[Prior Art] Conventionally, this type of IC card and IC card read/write device accesses the IC card and processes data even if the IC card is incorrectly inserted into the IC card read/write device. ing.

0003

[Problems to be Solved by the Invention] As mentioned above, in conventional IC cards and IC card read/write devices, even if an IC card is inserted incorrectly, the IC card is accessed, resulting in a contact error. There is a drawback that the IC card and circuit may be destroyed due to short circuit.

[0004] An object of the present invention is to eliminate the above-mentioned drawbacks and prevent incorrect insertion of an IC card by embedding a conductor inside an IC card and checking continuity when the IC card is inserted using an IC card reader/writer device. An object of the present invention is to provide an IC card reader/writer device which can prevent the IC card and circuit from being destroyed due to contact displacement of the IC card caused by incorrect insertion.

[0005]

[Means for Solving the Problems] The IC card of the first invention has a conductive wire embedded in a part thereof.

The IC card reader/writer device of the second invention sends a signal to the IC card of the first invention, the insertion part into which the IC card is inserted and set, and the conductive part of the IC card to determine whether or not there is continuity. It has a detection section that performs detection, and a control section that judges the result detected by the detection section and performs read/write processing of the IC card.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an IC card according to an embodiment of the first invention, and FIG. 2 is a block diagram of an IC card reader/writer device according to an embodiment of the second invention.

In FIG. 1, I of the embodiment of the first invention is shown.
The C card 1 has a conducting wire 2 inside the IC card.

In FIG. 2, an IC card reader/writer device according to an embodiment of the second invention is composed of an IC card 1, an insertion section 3, a detection section 4, and a control section 5.

[0011] Here, when the IC card 1 is inserted into the insertion section 3, it is set in the insertion section 3, and the insertion section 3 notifies the detection section 4 that the IC card 1 has been set. Next, the detection unit 4 applies electricity to the conductive wire portion of the IC card 1, detects whether it is conductive, and sends the detection result to the control unit 5. The control unit 5 is
Based on the result, it is determined whether the inserted state of the IC card 1 is normal or abnormal, and if the IC card 1 is electrically connected and normal, the IC card 1 is accessed. Then, data read/write processing is performed on the IC card.

0012

[Effects of the Invention] As explained above, the IC card and IC card reader/writer device of the present invention embeds a conductive wire inside the IC card, and checks continuity when the IC card is inserted into the IC card reader/writer device. ,
It is possible to prevent incorrect insertion of the IC card, and it is possible to prevent damage to the IC card and the circuit due to misalignment of the contacts of the IC card caused by incorrect insertion.
