Abstract

A channel selection method for reading tag information, a channel selection apparatus of an RFID reader applying the same, and an RFID reader. A channel selection apparatus of a radio frequency identification (RFID) reader equipped within a wireless communication portable terminal, includes a channel selection unit which selects a channel to read tag information stored in an RFID tag, and a channel determination unit which, when determining that the selected channel is not used by another RFID reader, determines the selected channel to be a channel to read the tag information. Accordingly, when a plurality of RFID readers reads out the tag information from the RFID tag almost at the same time, the interference among them can be avoided.
