Zusammenfassung:PROBLEM TO BE SOLVED: To provide a contactless IC card, a responding method and its program, etc. that control the collision of responses to the minimum. SOLUTION: The contactless IC card is provided in which a measuring means measures electromotive force derived from a reader/writer and a response timing deciding means decides a specific time slot based on a measurement result measured by the measuring means.
