Abstract
In accordance with an embodiment, a wireless tag communication apparatus according to the embodiment receives radio waves transmitted from a wireless tag by an antenna. The wireless tag communication apparatus changes a relative position of the antenna with respect to the wireless tag. The wireless tag communication apparatus reads tag data of the wireless tag at a plurality of relative positions of the antenna with respect to the wireless tag on the basis of the received radio waves and infers an arrangement region of the wireless tag from the tag data. The wireless tag communication apparatus sets a change speed of the relative position of the antenna with respect to the wireless tag.
