Abstract: According to one embodiment, a wireless-tagged label issuing apparatus includes a conveying roller to convey the label that has a wireless tag, an antenna for communicating with the wireless tag of the label, a tag reader to read a tag identification from the wireless tag via the antenna, and a control unit. The control unit is configured to compare the read tag identification to previously read tag identifications, and execute a first operation on the label if the read tag identification matches a previously read tag identification and a second operation on the label if the read tag identification does not match a previously read tag identification. For example, the first operation may be physically disabling the wireless tag, printing a voiding image on the label, or routing the label to a particular destination for invalid labels or the like.
