Claim:
A radio-frequency identification (RFID) system comprising: a sensor configured to detect a person entering a fitting room; and an RFID reader configured to read tag data from one or more RFID tags present in the fitting room by transmitting a reading radio wave having directivity in an inner direction of the fitting room according to detection of the person entering the fitting room by the sensor, wherein the RFID reader includes: a specific-data storing unit configured to store specific tag data of a specific RFID tag; and a control unit configured to transmit, in response to a determination that tag data coinciding with the specific tag data stored in the specific-data storing unit is not included in any of the tag data read from the one or more RFID tags present in the fitting room, all the tag data read from the one or more RFID tags to a host apparatus, and to prevent, in response to a determination that at least a subset of the tag data read from the one or more RFID tags coincides with the specific tag data stored in the specific-data storing unit, transmission of the tag data to the host apparatus and wait until a predetermined waiting time elapses before allowing the RFID reader to read subsequent tag data.
