Abstract

See full text

A wireless tag that is not guaranteed to be located within a predetermined area is prevented from being read as a valid wireless tag. A communication device includes: an antenna; a reference tag; a reception unit; and a determination unit. The reception unit uses the antenna to sequentially receive signals wirelessly transmitted from a reference tag whose relative position to the antenna is known and a reading target tag different from the reference tag. The determination unit determines that the signal transmitted from the reading target tag and received by the reception unit is invalid based on a phase of the signal transmitted from the reference tag and received by the reception unit.
