Abstract

[PROBLEMS] To provide a noncontact IC medium (23) which is applicable to a plurality of purposes. [MEANS FOR SOLVING PROBLEMS] A plurality of IC chips (21) are mounted on a noncontact IC medium (23), which has a loop antenna (22) for performing noncontact communication, and the IC chip (21) for control operation. The IC chips (21a, 21b) having different operation frequencies are used. In one working example, the loop antenna (22) is constituted with a shared loop antenna (22) shared by the IC chips (21). In another working example, independent loop antennas (22a, 22b) are connected to the IC chips (21a, 21b), respectively.
