An intelligent IC card read write device is presented here, laying emphasis on design procedures of its software and hardware. It is composed of 89C52 one chip microcomputer with the addition of a few peripheral interface circuits. The author puts forward the design thinking of a double card socket and optimizes the data manipulator of contact type IC card memory stack, by which not only the mass memory card can be read and written but also the management of confidential card can be carried out. The medical insurance card can also be finely operated. As shown by practice, this IC card read write device is stractarally compact, simple, reliable and widely applicable, it has fairly good price performance.
