Radio frequency identification tag

摘要

An RFID tag (9) having mounted thereon an IC chip (2) capable of receiving and delivering information from and to an external source without contact. In the RFID tag (9), a central axis (4) of its own antenna (1) having mounted thereon the IC chip (2) coincides with a center of the RFID tag (9), and an antenna width is controlled. That is, a position of the central axis (4) of the antenna (1) is controlled to correct the mass eccentricity of the RFID tag (9). Further, the RFID tag (9) is an RFID tag having mounted thereon the IC chip (2) capable of receiving and delivering information from and to an external source without contact, and an RFID tag having attached thereon the IC chip (2) at a position in which a first and a second antenna lengths are different from each other.
