An apparatus that identifies an object includes a frequency detector (112) that detects a frequency over which an RFID tag (102) communicates, and an object identifier (120) that identifies the object based at least in part upon the detected frequency. The frequency detector may detect a plurality of frequencies over which a plurality of RFID tags transmit information. The apparatus also optionally includes a frequency pattern generator that generates a frequency pattern that is indicative of an identity of the object, wherein the object identifier compares the generated frequency pattern with known frequency patterns to determine the identity of the object. |
