Abstract
A method for operator feedback when utilizing an RFID reader to find a specific RFID tagged article located in a plurality of RFID tagged articles is provided. Specific search criteria associated with a desired article are entered into the RFID reader. To begin searching for the specific RFID tagged article, the RFID reader sends out an interrogation signal to the RFID tags. An RFID tag responds with the desired RFID tag data. A processor compares the number of RFID tags matching the search criteria to the total number of RFID tags received. A feedback signal is generated according to the ratio of RFID tags matching the search criteria to the total number of RFID tags received.
