Abstract

Provided are a Radio Frequency Identification (RFID) tag and apparatus and method for locating a RFID tag without comparing arrival times of blink signals transmitted from the RFID tag in order to quickly trace a location of the RFID tag. The RFID tag includes a tag ID generator configured to generate a tag ID of the RFID tag, a blink generator configured to generate a plurality of sub-blink signals that form the blink signal, a sub-blink ID generator configured to generate sub-blink IDs for the generated sub-blink signals, a sub-blink ID inserter configured to insert the generated sub-blink IDs into the sub-blink signals, and a transmitter configured to transmit the blink signal having the tag ID and the sub-blink IDs.
