Abstract
Provided are a reader-tag integrated RFID apparatus and a method for controlling the same. The apparatus includes a tag unit for communicating with an external reader, and transmitting a response signal and data corresponding to a signal transmitted from the external reader to the external reader, a reader unit for selecting a channel between other reader and the reader-tag integrated RFID apparatus with a different delay time, and communicating with an external tag using a random value to minimize collision; and a controller for selectively activating one of the tag unit and the reader unit if it necessary.
