<p><P>PROBLEM TO BE SOLVED: To provide a non-contact type IC card compatible with various systems. <P>SOLUTION: The non-contact type IC card includes an IC chip mounted on a wiring board having a circuit wiring line 8, and an electromagnetic induction antenna 2, receives power supplied from an external reader/writer 17 through electromagnetic coupling with an electromagnetic induction antenna 18 thereof in an electrically non-contact state by the electromagnetic induction antenna 2, and transfers information to/from the reader/writer 17. The non-contact type IC card includes a switch 16 connected to the electromagnetic induction antenna 2, and five IC chips 11, 12, 13, 14, 15 connected to the switch 16, and allows a user to select the IC chip to be used according to the purpose of use. The non-contact type IC card also includes capacitors 21, 22, 23, 24, 25 for adjusting a Q value of the electromagnetic induction antenna 2 between the switch and the IC chips 11, 12, 13, 14, 15. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
