Description
実施形態による無線タグ読取装置は、複数の無線タグと無線通信を実行することで複数の無線タグから所定情報を取得する。この無線タグ読取装置は、第１取得部と、第２取得部と、を有する。第１取得部は、第１の伝送速度の無線通信で所定の要求を送信することで、第１の無線タグから所定情報を取得し、前記要求に対する前記第１の無線タグからの応答の数を示す値が第１しきい値以下になった場合に、前記所定情報の取得を終了する。第２取得部は、第１取得部による所定情報の取得が終了した後、第１の伝送速度よりも遅い第２の伝送速度の無線通信で要求を送信することで、第１の無線タグとは異なる第２の無線タグから所定情報を取得し、前記要求に対する前記第１の無線タグからの応答数が第２しきい値以下になった場合に、前記所定情報の取得を終了する。 The wireless tag reading device according to the embodiment acquires predetermined information from the plurality of wireless tags by executing wireless communication with the plurality of wireless tags. This wireless tag reading device has a first acquisition unit and a second acquisition unit. The first acquisition unit acquires predetermined information from the first wireless tag by transmitting a predetermined request by wireless communication at the first transmission speed, and the number of responses from the first wireless tag to the request. When the value indicating is equal to or less than the first threshold value, the acquisition of the predetermined information is terminated. After the acquisition of the predetermined information by the first acquisition unit is completed, the second acquisition unit transmits the request by the wireless communication of the second transmission speed slower than the first transmission speed, so that the second acquisition unit and the first wireless tag can be used. Acquires predetermined information from different second wireless tags , and ends acquisition of the predetermined information when the number of responses from the first wireless tag to the request becomes equal to or less than the second threshold value.
