Title: Non-contact ic card
Inventor: SUZUKI HIDETOSHI
IPC: B42D15/10
Filed: 2000-05-02
Abstract: PROBLEM TO BE SOLVED: To make surely performable collective read/write operation with an IC card reader/writer even in the state of overlapping plural IC cards each other. SOLUTION: A non-contact IC card 30 has a circular external form and can be stuck to a postcard 50 while being suitably rotated. Therefore, the position of an antenna 34 changes corresponding to the rotating angle of the non- contact IC card. When simultaneously reading/writing plural non-contact IC cards 30a,..., 30h,... while using the IC card reader/writer, by generating a magnetic field by the IC card reader/writer, a current flows to the antenna 34 and this current is supplied to an IC chip 32 so that read/write operation can be started. In that case, since the mutual inductance of an antenna 34a or 34h can be reduced, power can be efficiently generated and collective read or write operation can be surely performed.
