RFID tag communication system and RFID tag communication apparatus

An RFID tag communication system comprising:

• an RFID tag communication apparatus capable of communicating with a plurality of RFID circuit elements, each of the RFID circuit elements having a tag antenna that transmits and receives information and an IC circuit part that stores information;
• and
• an operation terminal that enables operation of said RFID tag communication apparatus,
• said RFID tag communication apparatus having:
• a communication antenna that forms a communication range that includes said RFID circuit elements and performs wireless communication;
• and
• at least one information acquisition device that attempts to acquire tag identification information from said RFID circuit elements positioned within said communication range by selectively using a plurality of communication protocols different from each other;
• said operation terminal has a storage processing device that performs predetermined storage processing with respect to a plurality of tag identification information with associating with each communication protocol, said plurality of tag identification information being acquired by said at least one information acquisition device with using said plurality of communication protocols different from each other.
