<p>Even if IC tags adhered to the outer face of a physical distribution container or a pallet overlap each other, the transmissions to the IC tags can be satisfactorily performed to write and read data in and from the IC tags. Wireless IC tags (2, 3) are of the passive type including antennas (22, 32) formed on base sheets (21, 31) and IC chips (23, 33) mounted on the base sheets in a manner to conduct with the antennas (22, 32). When the surfaces of the two IC tags (2, 3) are overlapped in all directions, the antenna (22) is formed to have a pattern having no overlap with the antenna (32) of the partner IC tag. The IC tags (2, 3) are mounted on the outer faces of either a container for containing contents or a conveyer pallet for placing containers.</p> |
