INSTALLATION STRUCTURE OF TAG FOR RFID, AND RFID SYSTEM PROVIDED WITH TAG

摘要

PROBLEM TO BE SOLVED: To provide an installation structure of a tag, and an RFID system provided with the tag capable of communicating data even when the tag is embedded in a conductive member such as a metal. SOLUTION: In installing the tag 1 for RFID for communicating data with a reader 2 by a built-in antenna in the conductive member such as a metal member 4, the metal member 4 is provided with at least one slit 5 which has a width larger than 1μm and passes in a normal direction of an antenna plane along a surface approximately orthogonal to a plane formed by the antenna built in the tag 1 and contacting or crossing with at least a part of the tag 1. When a magnetic flux generated from the antenna passes through the slit 5, the tag 1 and the reader 2 can communicate.
