ID TAG PACKAGE AND RFID SYSTEM

摘要

[PROBLEMS] To provide an ID tag package for RFID, which performs excellent wireless communication regardless of existence of external metal or water and is strong against stresses from the external even under severe use environment, and to provide a RFID system using such package. [MEANS FOR SOLVING PROBLEMS] In the RFID system, an ID tag package (20) has a structure, which covers an ID tag (22) for RFID and has thicknesses (L1, L2) required for reducing electromagnetic wave attenuation due to existence of at least external metal or water. The RFID system includes an elastic layer (24) which can relax stresses from the external.
