Cards combination device / product

Cards combination device

The internal structure of the cards such as bank card are embedded within an integrated circuit. We can make a small card with a chip, wire , and a chuck which is full of metal coil. Small card can be inserted into the chuck which has eight small rooms for cards. Control of the location of the small card makes chips to produce work and non-work states. The non-working small cards are connected to the system by the wire. And the small working card is connected by the chip. Changing the number and the size of coil makes it meet the requirements of its work.
