Eight cards combined / product industry trades

Eight cards combined

My idea is to put the size of the eight card into a card, but eight card is independent from each other at work.We can make a small card with a chip and a not connected to any of the original wire and a chuck is full of metal coil. Small card can be inserted into the chuck,.The chuck has eight small card socket. Control the location of the small card on thechuck make chips to produce work and non-work state,.The non-work small connected to the small cards don't connected to the wire and the small work card connected to the chip. By changing the number and size of coil to ensure the electromotive force meet the requirements.
