Patent ID: 8416060

Claim:
A method for reading a target radio frequency identification (RFID) tag at an RFID reader device, the method comprising: commencing transmission of an interference signal from the reader device; transmitting a do not respond command signal from the reader device while the interference signal is still being transmitted, whereby the do not respond command signal instructs non-target RFID tags to not respond to an interrogation signal, and wherein the target RFID tag does not process the do not respond command signal because the do not respond command signal is blocked by the interference signal; stopping transmission of the interference signal from the reader device; transmitting the interrogation signal from the reader device after the interference signal is no longer being transmitted; and receiving a response signal at the reader device from the target RFID tag that enables the reader device to read the target RFID tag wherein RFID tags respond to the interrogation signal unless a do not respond command signal has been received by the RFID tag.
