Abstract
A tag reading device includes an external interface, an RFID interface, a buffer memory, and a processor. The external interface communicates with a higher-level device. The RFID interface reads tag information from an RFID tag. The buffer memory sequentially records the tag information read from the RFID tag using the RFID interface. The processor extracts a commodity code for specifying a commodity from the tag information recorded in order in the buffer memory and transmits the commodity code to the higher-level device through the external interface, and updates a transmission start pointer indicating untransmitted tag information in the buffer memory.
Claims16
A tag reading device comprising:
- an external interface configured to communicate with a higher-level device;
- an RFID interface configured to read tag information from an RFID tag;
- a buffer memory configured to sequentially record the tag information read from the RFID tag using the RFID interface;
- and
- a processor configured to:
- extract a commodity code for specifying a commodity from the tag information sequentially recorded in the buffer memory,
- transmit the commodity code to the higher-level device via the external interface, and
- update a transmission start pointer indicating untransmitted tag information in the buffer memory.
