15. 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 that obtains signal parameter information associated with the RFID tags; processing circuitry that uses the signal parameter information for one or more tags of the RFID tags and weights at least one signal parameter value of the signal parameter information for the one or more tags of the RFID tags to calculate tag scores for the one or more RFID tags, wherein the tag scores are used to identify the specific RFID tag.
17. The system of claim 15 , wherein the RFID reader circuitry obtains signal parameter values including a received signal strength indication (RSSI) value and an occurrence frequency value for the one or more RFID tags and the processor circuitry is operable for using RSSI values and occurrence frequency values to calculate tag scores for the one or more tags of the RFID tags.
