To easily allow efficient reading of a wireless tag.SOLUTION: A wireless tag makes a transition alternately between a first state and a second state according to reading of information. Designation means designates, for each of a plurality of business operations, only the first state or the first state and the second state as an object of reading, and designates a suitable reading state. The reading state is one of a first reading state in which after reading of the wireless tag, a response from the wireless tag is blocked over a first blocking time regardless of the presence or absence of power supply to the wireless tag, a second reading state in which when periodic power supply to the wireless tag is continued after reading of the wireless tag, a response from the wireless tag is blocked over a second blocking time, a third reading state in which when periodic power supply to the wireless tag is continued after reading of the wireless tag, a response from the wireless tag is blocked over a third blocking time, and a fourth reading state in which when power supply to the wireless tag is continued after reading of the wireless tag, a response from the wireless tag is blocked.SELECTED DRAWING: Figure 7 【課題】無線タグの読み取りを効率的に行うことを容易に可能にする。【解決手段】無線タグは、情報の読み取りに応じて第１状態と第２状態とを交互に遷移する。指定手段により、複数の業務ごとに、読取対象として第１状態のみ又は前記第１状態および第２状態を指定するとともに、適する読取状態を指定する。読取状態は、無線タグの読み取り後に無線タグへの電力供給の有無に関わらず無線タグからの応答を第１の抑止時間に亘って抑止する第１読取状態と、無線タグの読み取り後に無線タグへの定期的な電力供給を続けた場合に無線タグからの応答を第２の抑止時間に亘って抑止する第２読取状態と、無線タグの読み取り後に無線タグへの定期的な電力供給を続けた場合に無線タグからの応答を第３の抑止時間に亘って抑止する第３読取状態と、無線タグの読み取り後に無線タグへの電力供給を継続した場合に無線タグからの応答を抑止する第４読取状態とである。【選択図】図７
