8. The system of claim 5 wherein the processing circuitry determines a difference between a highest tag score and a next highest tag score for the one or more RFID tags and compares the difference to a first threshold value to identify the specific RFID tag using the tag scores.
10. The system of claim 8 wherein when the difference does not exceed the first threshold value, to again obtain signal parameter information associated with the RFID tags and to calculate another tag score for the one or more of the RFID tags and to determine a difference between a highest another tag score and a next highest another tag score and to compare the difference between the highest another tag score and the next highest another tag score to the first threshold value to identify the specific RFID tag using the another tag scores.
