【0002】 [0002]
従来、RFIDタグの形状は、カード状、コイン状、棒状などや、またガラスにて封止されたカプセル状のものや、金属にて封止されたものなどが一般的であった。 Conventionally, the shape of the RFID tag, a card, a coin shape, a rod or the like, also capsular ones and sealed with a glass, such as those sealed with metal were common.
そして、これらのRFIDタグは、機能こそ保持するものの、見栄えが悪かったり、添付された商品の商品イメージを損なったり、顧客がそれほど関心を引くデザインではないのが一般的であった。 And, these RFID tags, although the function what to hold, appearance or bad, or impair the product image of the attached goods, the customer is not a design so interesting were common.
また、種々の外形形状を有するICキャリアとしては、既にアプリケーション毎に異なる外形形状を有するICキャリアも知られているが、これは添付する商品のイメージアップを図る目的ではなく、ICキャリアの使用目的を外形によりわかりやすくしたものである。 As the IC carrier having various outer shapes, have been already known IC carrier having a different outer shape for each application, this is not for the purpose of achieving the image enhancement of the product attached, the use of IC carrier purposes the one in which was easy to understand by the external shape.
