Patent ID: 8295799

Claim:
A method of communication with a transponder for use by a device including a plurality of inductor coils having a first inductor coil and a second inductor coil, the method comprising: selecting the first inductor coil of the plurality of inductor coils, wherein the selecting of the first inductor coil includes coupling the second inductor coil to ground; scanning to detect the transponder using the first inductor coil; determining that the transponder is not detected by the scanning using the first inductor coil; selecting the second inductor coil of the plurality of inductor coils in response to the determining, wherein the selecting of the second inductor coil includes coupling the first inductor coil to ground; re-scanning to detect the transponder using the second inductor coil; detecting the transponder using the second inductor coil in response to the re-scanning; and communicating with the transponder in response to the detecting.
