<p><P>PROBLEM TO BE SOLVED: To provide an RFID tag reader/writer device that will not start radio communication with an RFID tag in an abnormal state. <P>SOLUTION: Before radio communication with an RFID tag is started (S12: Yes), communication to a built-in IC tag chip 56 side is performed (S18). A determination is made as to whether or not data read from the chip 56 is normal and, if the data is determined to be normal (S20: Yes), a read/write to the RFID tag via an RF antenna 58 is started (S22, S28). Since the read/write to the RFID tag via the RF antenna is started only when communication to the built-in IC tag chip 56 side can be performed properly, the possibility that radio communication to the RFID tag in an abnormal state is started is precluded. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
