<P>PROBLEM TO BE SOLVED: To provide a radio reader/writer device for an unexpensive non-contact IC card which connects between a proximity type non-contact IC card reader/writer device and host computer by radio. <P>SOLUTION: The radio reader/writer device for a non-contact IC card of the first invention having a communication means for communicating with the host computer, an IC card security communication module using a first carrier frequency, a microcomputer, a memory means, and a clock circuit, communicates with the host computer by radio communication using a second carrier frequency. In the radio reader/writer device for a non-contact IC card of the second and third inventions having the communication means for communicating with the host computer, a communication means for communicating with the IC card using the first carrier frequency, and the IC card security communication module, the communication means for communicating with the IC card communicates with IC card security communication module by radio communication using the second carrier frequency. <P>COPYRIGHT: (C)2007,JPO&INPIT |
