Patent ID: 8072327

Claim:
A component for a Radio Frequency Identification (RFID) reader to communicate with an RFID tag, the tag having received a first command, and backscattered a first reply encoding a functional content responsive to the first command, the first reply using a first delay before the tag starts backscattering the first reply after receiving the first command, comprising: an operational processing block for causing to be transmitted to the tag a custom timing command, the tag then backscattering a second reply that encodes the same functional content as the first reply, the second reply using a second delay before the tag starts backscattering the second reply after receiving a most recent command prior to backscattering the second reply, the second delay different from the first delay responsive to receiving the custom timing command, in which if the tag was in a disabled state when it received the custom timing command then the second delay would be the same as the first delay, if the tag was in an enabled state when it received the custom timing command then the second delay would be different from the first delay, and an Enable command transmitted while the tag is in the disabled state causes the tag to transition to the enabled state.
