There is provided an RFID tag which includes a first sheet portion including a first projection-depression portion formed in a longitudinal direction or a first groove portion formed in a direction forming an angle with the longitudinal direction, an antenna formed on a surface of the first sheet portion, the antenna being flexible and elastic, an integrated circuit chip electrically connected to the antenna, a second sheet portion including a second projection-depression portion formed in the longitudinal direction or a second groove portion formed in a direction forming an angle with the longitudinal direction, the antenna and the integrated circuit chip being covered between the first sheet portion and the second sheet portion, and a package member covering the first sheet portion and the second sheet portion, the package member being flexible and elastic.

RFID tag

An RFID tag includes: a base sheet in which a plurality of first slits are formed to extend alternately from two opposite sides from an end of the base sheet; an antenna pattern provided on the base sheet by folding the antennal pattern to avoid the first slits; an RFID chip provided over the base sheet and electrically connected to the antenna pattern; an elastic sheet provided over any one of a top surface and a bottom surface of the base sheet; and a protective sheet provided on a surface of the elastic sheet opposite to the surface that is in contact with the base sheet and including second slits formed to correspond in position to the first slits of the base sheet.

RFID tag and RFID system

A wireless tag includes: an antenna; an integrated circuit configured to be electrically connected to the antenna; a package configured to integrally subject the antenna and the integrated circuit to packaging; and a boundary portion configured to be located between a first portion including the integrated circuit in the package and a second portion not including the integrated circuit, wherein the boundary portion is configured so as to be more easily torn apart than a portion other than the boundary portion in the package.

Wireless tag

An RFID tag includes an inlay which has a base, an antenna formed on the base, and an IC chip. The IC chip is enclosed in a surface mount package and soldered to the antenna and carries out radio communication through the antenna. The RFID tag further includes underfill that fills a gap between the base and the surface mount package, and a sheath protecting material enclosing the entire inlay.
