ABSTRACT:
An RFID verifier includes a transmit signal strength indicator (TSSI) and a receive signal strength indicator (RSSI). Using the TSSI, the RFID verifier may determine the amount of power an interrogated RFID tag is illuminated with. Similarly, using the RSSI, the RFID verifier may determine the amount of power returned to the RFID verifier by the RFID tag. By processing the returned power and the illuminating power with a transfer function, the RFID verifier may provide an absolute indicia of quality for the interrogated RFID tag.
