Abstract

　複数のＲＦＩＤタグを収納可能で、ＲＦＩＤリーダから磁界を印加されたとき、所望の１つのＲＦＩＤタグのみを起動させて読取り可能としつつ、その他のＲＦＩＤについては読取りを不能とすることのできるＲＦＩＤ用カード収容具およびＲＦＩＤ用通信補助シートを提供する。 　磁性体層と、導電体層と、間隙層とを備えた板状部材を用いて、ＲＦＩＤ用カード収容具およびＲＦＩＤ用通信補助シートを作製する。このＲＦＩＤ用カード収容具および通信補助シートにおいて、板状部材は第１のＲＦＩＤタグと第２のＲＦＩＤタグとの間に配置されるよう用いられる。すると、第１のＲＦＩＤタグ側に位置するＲＦＩＤリーダから磁界を印加されたとき、第１のＲＦＩＤタグは起動されるので、ＲＦＩＤリーダへの返信が行われる。一方、第２のＲＦＩＤタグは、導電体層で発生した渦電流によって反磁界が生じることにより起動されないので、返信は行われない。
