[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-contact type IC card capable of writing and reading information in a non-contact state, and more particularly to a non-contact type IC card by an electromagnetic induction method.

[0002]

2. Description of the Related Art In recent years, with the development of an information-oriented society, information is recorded on a card, and information management and payment using the card are performed.

In information management using such a card, a contactless IC card equipped with an IC capable of writing and reading information in a contactless state with respect to the card is excellent in convenience. Due to sex, it is rapidly spreading.

In a non-contact type IC card capable of writing and reading information in a non-contact state, an electromagnetic coupling system utilizing mutual induction of coils by an alternating magnetic field and an induced power by dielectric flux of two coils are used. Communication by using a capacitor principle between the card side and the external information writing / reading side antenna, and the electromagnetic induction method using There are two types, one is the electrostatic coupling method, and the other is the optical method that uses the energy modulation of light by blinking near-infrared light at high speed. Among these, the induced power by the induced magnetic flux of two coils is used. The electromagnetic induction method is most widely used because of its excellent transparency and high reliability of data transmission.

7A and 7B are views showing an example of a conventional non-contact type IC card by an electromagnetic induction system. FIG. 7A is a view showing a surface structure, FIG. 7B is a view showing an internal structure, and FIG. 7C is a view. It is a figure which shows a laminated structure.

Conductivity for supplying current to the IC module 711 by electromagnetic induction from an information writing / reading device (not shown) provided outside, and performing writing and reading of information to and from the IC module 711 in a non-contact state. Layer 712 in which a flexible antenna 712 is formed in a coil shape and white PET or the like is configured to be capable of printing arbitrary information, and is laminated so as to sandwich the inlet 710.
20a, 720b and a transparent film layer, and the inlet 710 and the intermediate layers 720a, 720 laminated on each other.
surface sheets 730a, 73 laminated so as to sandwich b and
0b, the inlet 710, the intermediate layers 720a and 720b, and the intermediate layers 720a and 720.
b and the top sheets 730a and 730b are adhered to each other by an adhesive layer (not shown).

In the non-contact type IC card 700 configured as described above, when it approaches an information writing / reading device provided outside, a current is applied to the antenna 712 by electromagnetic induction from the information writing / reading device. This current flows through the contact 7
14 to the IC module 711, so that the information writing / reading device I
Information may be written in the C module 711, or information written in the IC module 711 may be read by the information writing / reading device.

When printing desired information on such a non-contact type IC card 700, the intermediate layers 720a and 720b are formed.

Here, when the non-contact type IC card does not perform a predetermined function, in the conventional non-contact type IC card, the inlet cannot be visually recognized from the outside as described above. In order to check whether the cause is the damage of the IC module or the disconnection of the connecting portion between the IC module and the antenna, I
There is a problem in that the layers stacked on the C module have to be scraped off, which takes time and effort.

Information can be printed on a non-contact type IC card by printing the information on the intermediate layer. However, the representation of the information by printing is easily imitated, and therefore the card itself is forged. There is a risk that it will be done.
