Patent ID: 7889056

Claim:
A combination of a separate radio frequency identification (RFID) device and a separate RFID blocking device, each being adapted to be positioned separately into a container so that the separate RFID device and the separate RFID blocking device are each adjacent the other, the combination comprising: a separate RFID device adapted to be positioned in a container; and a separate RFID blocking device adapted to be positioned in the container adjacent the separate RFID device to detect and block an attempted read of the otherwise separate RFID device from the container when an RFID interrogation device is positioned to read the separate RFID device from the container, the separate RFID blocking device being positioned to operatively receive power from the RFID interrogation device during an attempted read of the separate RFID device and including an RFID interferer positioned to produce interfering signals responsive to a response signal from the separate RFID device that interferes with the transmission of the response signal from the separate RFID device to the RFID interrogation device to thereby interfere with the ability of the separate RFID device to transmit to the RFID interrogation device when the RFID interrogation device is positioned to read the separate RFID device from the container, the separate RFID blocking device further being adapted to be positioned separate and spaced apart from the separate RFID device to thereby allow an attempted read of the separate RFID device by the RFID interrogation device when the separate RFID device is no longer positioned adjacent the separate RFID blocking device.
