  2. Description of the Related Art In recent years, inventory management systems that manage inventory of products and the like using RFID (Radio Frequency IDentification) technology are known. In such an inventory management system, a wireless tag such as an RFID tag is attached to a product in advance. The wireless tag reading device collectively reads the wireless tags of the products arranged on the product shelf by irradiating radio waves over a wide range. Thereby, the wireless tag reader can easily check the stock of the product.

  By the way, in apparel stores, there are products that are stored in stores, even though they are already sold products such as refurbished products. Products that have already been sold are not in stock and must be excluded from aggregation. However, since the RFID tag reader irradiates radio waves over a wide range, there are cases where already sold products are counted as inventory.

  The problem to be solved by the present invention is to provide a wireless tag reader and program capable of preventing unintended tag information aggregation.

  The wireless tag reader according to the embodiment includes a receiving unit, an extracting unit, and an output unit. The receiving means receives tag information indicating a state of the article from a wireless tag attached to the article. The extraction means extracts the tag information satisfying a preset extraction condition from the tag information received by the reception means.
