1. A system for identifying a specific RFID tag, the system comprising:
- RFID reader circuitry that sends and receives RF signals to detect RFID tags and for obtaining signal parameter information associated with the RFID tags including a plurality of different signal parameter values associated with the RFID tags;
processing circuitry that uses the signal parameter information for one or more tags of the RFID tags to calculate a tag score for the one or more RFID tags and gives a different weight to at least one of the signal parameter values over another signal parameter value in the calculation of the tag score by multiplying the at least one signal parameter value by a respective multiplier.

Abstract
A system and method for identifying a specific RFID tag includes RFID reader circuitry, such as within an RFID reader, configured for sending and receiving RF signals to detect RFID tags and for obtaining signal parameter information associated with the RFID tags. Processing circuitry is configured for using the signal parameter information for one or more tags of the RFID tags and calculating a tag score for the one or more RFID tags. The processing circuitry is further configured for determining a specific RFID tag using the tag scores for the one or more RFID tags.
