The card that uses present this technology to make has following shortcoming:

1) operation of smear layer moulding water is wanted 4 times more than in the fabrication process, paste PET or PVC card body material is wanted 4, and so loaded down with trivial details operation will expend great amount of manpower and time, also is very big for inventory charge simultaneously;

2) existing mini contactless IC card all is by special-purpose laminating machine with English class layer (compositions such as antenna, chip, card base), patterned layer, in the regular hour, carry out High Temperature High Pressure to blocking base, patterned layer etc., it is pressed into a card, cost will increase like this, need a large amount of lamination time simultaneously and purchase special laminating apparatus.This procedure has increased production cost.

3) patterned layer of active card prints in advance, the patterned layer that prints is laminated on the card body, final card pattern can not be changed, can not change, and be 10 years the theoretical service life of a card, a width of cloth pattern is constant in 10 years, lack new meaning, more do not meet modern young people's fashion theory.

4) existing antenna manufacture craft is difficult to make the English class layer that guarantees reading/writing distance, wants to guarantee reading/writing distance, must try every possible means to strengthen the signal transfer strength of card and read-write heads, and prior art does not have solution as yet.

5) existing card English class layer (circular integrated circuit card body is just laid the card material of antenna, chip) generally adopts materials such as PET, PVC, but its softness, is bent easily and is out of shape, and can not well protect antenna and chip.
