摘要： An RPID tag and a reader, a method of identifying an RFID tag, and an anti-collision method of an RFID tag are provided. An epoch size determination unit determines the size of an epoch signal having a preset size. An identifier request signal generator generates an identifier request signal including a prefix and a number of a frame to perform selected identification among frame numbers intrinsically allocated to frames of the determined quantity within the size of an epoch signal. If tag identifiers are received from a plurality of RFID tags through a frame to perform identification, an anti-collision unit generates a sub-prefix by increasing a bit of a prefix included in an identifier request signal and then enables the identifier request signal generator to generate an identifier request signal including a sub-prefix and a number of a frame to perform identification. A communication unit transmits an epoch signal and an identifier request signal including a prefix and a number of a frame to perform identification, and receives a tag identifier including a prefix from an RFID tag, having received the identifier request signal. If a prefix of a tag identifier received through a frame to perform identification is identical to the prefix included in the identifier request signal, a tag identification unit identifies an RFID tag, having transmitted the tag identifier.
