RADIO INFORMATION STORAGE MEDIUM DEVICE, PASSBOOK AND THE LIKE HAVING IT, IDENTIFICATION CONFIRMATION SYSTEM USING IT, AND ISSUE SYSTEM FOR IT

摘要

PPROBLEM TO BE SOLVED: To selectively gain a plurality of functions in compliance with the number of radio information storage media without causing any defective communication due to mutual interference between respective radio information storage media when a plurality of radio information storage media are overlapped to each other. PSOLUTION: This radio information storage medium device is constructed by foldably layering a support, an IC part 20 arranged in the support for storing optional information, and a plurality of radio information storage media 14a-14c having a coil type antenna 22 connected to the IC part for reading/writing information from/to the IC part 20 without any contact. The coil antenna 22 for the respective radio information storage media 14a-14c disables transmission/receipt of information when the radio information storage media 14a-14c of the coil type antenna 22 are folded and enables the transmission/receipt of the information when they are opened.
