摘要：
A system and method for determining a failed wireless tag includes capturing images of articles having wireless tags, recognizing an image including wireless tags from among captured images calculating a number of wireless tags and distance information from the reader to each wireless tag based on the recognized image including wireless tags; changing a read range of the reader based on a location wireless tag having a predetermined distance information from the reader; and changing the read range of the reader when a number of wireless tags read by the reader and a number of wireless tags calculated do not match and determining a failed wireless tag based on the changed read range and distance information calculated.
