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 comparing the returned power to the amount used to illuminate the interrogated tag, the RFID verifier may provide an indicia of quality for the interrogated RFID tag.
