1. A radio frequency identification (RFID) system comprising:

  • an RFID tag; and

    an RFID signal strength measuring reader that measures a strength of a signal received from the RFID tag, creates control information used to set an amplification amount of the RFID tag by using a value of the measured strength to include the control information in an output signal, and sends the output signal to the RFID tag;

    wherein the RFID tag, if the signal sent from the RFID reader is received, extracts internal information from the received signal, sends the information to the RFID reader as an output signal, and at this time, extracts the control information included in the signal sent from the RFID reader to adjust a strength of the output signal according to a value of the control information.
