A radio frequency identification (RFID) technology which overcomes a cross-reading problem by using visible light recognition and identification values. An RFID reader terminal includes a visible light transmitter configured to transmit a visible light signal including an identification value of the RFID reader terminal, a radio frequency (RF) receiver configured to receive an RF signal including an identification value of an RFID tag terminal and information of the RFID tag terminal from the RFID tag terminal, and a reader controller configured to determine whether the identification value of the RFID reader terminal is identical to the identification value of the RFID tag terminal. In addition, there is provided an RFID tag terminal corresponding to the RFID reader terminal.
