According to one embodiment, a wireless tag communication apparatus includes a plurality of communication units configured to communicate with a wireless tag. The communication units are disposed such that communicable ranges of the communication units overlap each other. A control unit controls each of the plurality of communication units to alternate between a communication state and a pause state. When the wireless tag is positioned within communication ranges of both first and second communication units of the plurality of communication units, the control unit controls the first communication unit to be in the communication state and the second communication unit to be in the pause state.
