RFID TAG READER, RFID TAG READING SYSTEM, METHOD FOR PERFORMING RFID TAG READING PROCESS AND COMPUTER-READABLE RECORDING MEDIUM
First Claim
1. An RFID tag reader comprising:
- a signal intensity obtaining part configured to obtain signal intensities of a first RFID tag and one or more second RFID tags that are read at plural read processes;
a read-number obtaining part configured to obtain a number of RFID tags, among the first and the second RFID tags, that are read at the same read process;
a processing part configured to weight the signal intensity of the first RFID tag obtained by the signal intensity obtaining part based on the number obtained at the corresponding read process; and
a selecting part configured to select a read result of the first RFID tag based on the signal intensity of the first RFID tag weighted by the processing part.
