<P>PROBLEM TO BE SOLVED: To provide a case for a contactless IC card accommodating a plurality of contactless IC cards, enabling reading of only one card inside the case. <P>SOLUTION: By placing an electromagnetic wave shield sheet and the contactless IC card apart with a predetermined distance so as not to be disposed adjacently, it is possible to prevent antenna operation of the contactless IC card from being impeded. Accordingly, it is possible for an external card read/write unit (or may also be called as reader/writer) to transmit/receive data to/from only one contactless IC card accommodated inside the case. <P>COPYRIGHT: (C)2008,JPO&INPIT |
