Abstract

An RFID tag has an IC chip and an antenna connected to the IC chip, the RFID tag including: a spacer that has elasticity; a first locking section that is formed around the IC chip; a second locking section that is arranged in a position apart from the first locking section across the spacer, is displaced toward the first locking section and locked on the first locking section by pressing force with which the spacer is pressed, and applies reactive force against the pressing force around the IC chip via the first locking section when the pressing force is removed; and a destruction section that destroys the IC chip or the antenna with the reactive force from the second locking section. The invention can prevent the unauthorized use of RFID tag to be bonded to an intended article.

Description

RFID tags Technical field The present invention relates to a radio frequency identification (RFID) tag including an integrated circuit (IC) chip and an antenna connected to the IC chip. Background technique In order to prevent unauthorized use of RFID tags, there are known technologies in which once the RFID tag is attached to a target item, it can only be destroyed by removing the upper part of the RFID tag. [Patent Document 1] Japanese Patent Laid-Open No. 2000-48147 [Patent Document 2] Japanese Patent Laid-Open No. 2005-242971 [Patent Document 3] Japanese Patent No. 3636202 The aforementioned RFID tag for preventing unauthorized use needs to be bonded to the target item. Therefore, such RFID tags are not suitable for RFID tags that are not adhered to target items. In addition, if such an RFID tag is removed from the target article, the RFID tag for preventing unauthorized use becomes invalid. Summary of the invention The present invention has been completed in conside...
