Abstract
An RFID tag reader is disclosed that includes a signal intensity obtaining part configured to obtain signal intensities of a first RFID tag and a second RFID tag 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.
