ABSTRACT:
The RFID tag information communicating device is provided with a cartridge constructed in such a manner that a plurality of RFID circuit elements are stored and can be sequentially taken out therefrom, and an antenna for performing transmitting/receiving operations in a radio communicating operation between the own antenna and an antenna of a sequentially derived RFID circuit element, first access information for accessing RFID tag information of an IC circuit part is produced by a signal processing circuit; and the produced first access information is transmitted by a transmitting portion so as to access the RFID tag information of the IC circuit part. After the access operation is carried out, a control circuit judges as to whether or not the access operation can succeed, and controls a magnitude of transmission power from the transmitting portion in response to this judgment result.
