CPU card is a single-chip microcomputer, with internal controller, memory, time control logic unit.

CPU Card, Java card, combi card, widely used in one card pass system, school management system, bus card, borough management system, etc.

CPU card, whose silicon chip itself has MPU, and near the silicon chip circuit has register, memorizer, circuit and so on. So the CPU card becomes the smart card, meanwhile the IC memory space will become bigger and bigger.

Because CPU card has become an absolute microprogramming unit, so itself has a operating system (COS). Under the support of COS, CPU card becomes the most security and reliable IC card, so the serviceable range is more extensive than before.
