Abstract A structure of a system using an IC card is simplified. A controller and active antennas are connected to each other through a bus. The controller transmits a command outputted from a host computer and including an ID for discriminating the active antennas to all the active antennas connected to the bus. The respective active antennas judge whether or not the received command is directed to itself by checking the contained ID. In the case where it is judged that the command is directed to itself, transfer of data to the IC card is performed, and the result is transferred to the controller through the active antenna and the bus.
