To provide a data writing device for effectively specifying a radio tag having the strongest radio wave intensity, and a processing method.SOLUTION: According to an embodiment, a data writing device includes a reader and a processor. The reader receives a radio wave from a radio tag storing a first identifier and a second identifier, and measures the radio wave intensity of the radio wave received from the radio tag. The processor respectively determines the radio wave intensity of radio waves received from a plurality of radio tags by acquiring the first identifiers from the plurality of radiowaves through the reader, sets a reading threshold between the strongest radio wave intensity and the next strongest radio wave intensity in the radio wave intensity of the radio waves received from the plurality of radio tags, and acquires the second identifier from a radio tag of radio wave intensity that exceeds the set reading threshold through the reader.SELECTED DRAWING: Figure 1 【課題】最も電波強度が強い無線タグを効果的に特定するデータ書込装置及び処理方法を提供する。【解決手段】実施形態によれば、データ書込装置は、リーダと、プロセッサと、を備える。リーダは、第１の識別子と第２の識別子とを格納する無線タグからの電波を受信し、前記無線タグから受信する電波の電波強度を測定する。プロセッサは、前記リーダを通じて、複数の無線タグから前記第１の識別子を取得することで、前記複数の無線タグから受信する電波の電波強度をそれぞれ判定し、前記複数の無線タグから受信する電波の前記電波強度の中で最も強い電波強度と次に強い電波強度との間に読取閾値を設定し、前記リーダを通じて、設定された前記読取閾値を上回る電波強度の無線タグから前記第２の識別子を取得する。【選択図】 図１
