    Abstract: An RFID tag inspection method includes the steps of transmitting a measurement signal from a reader/writer simultaneously to a plurality of RFID tags arrayed on a collective base member and configured to process radio signals, receiving response waves from the individual RFID tags in a batch by the reader/writer, and determining, based on strengths and a number of received signals read by the reader/writer, whether or not the individual RFID tags are acceptable. Thus, acceptance/rejection inspection can be performed on the plural RFID tags, which are arrayed on the collective base member, in a batch.
