Commodity sales registration processing system and commodity information registering apparatus

摘要

Tag information which has been previously read but is not currently read is retrieved every time tag information is collectively read by a wireless tag reading device (2). When corresponding tag information is detected, sales information of a commodity is acquired from this tag information, and the acquired sales information is registered in a sales registering section. Further, display contents in a display device (4) are changed in response to detection of the tag information which has been previously read but is not currently read. Furthermore, when information concerning a commodity for sale is input through a barcode reader (3), sales information of the commodity is acquired from this input information, and the acquired sales information is registered.
