Abstract: Methods and systems of processing transponder signals received from transponders to identify the transponders are provided. A first signal having a first signal strength is received from a first transponder, and a reference signal strength is determined based on the first signal strength. A second signal having a second signal strength is received from a second transponder. The reference signal strength is compared with the second signal strength. The first transponder is determined to be within a predefined range based on the second signal strength being greater than the reference signal strength.
