Abstract

In one embodiment, a method includes, by a base station, communicating a challenge to a transponder through a first communication link; and establishing a second communication link with the transponder. The second communication link is a capacitive link. The method also includes receiving a first response to the challenge through the first communication link with the transponder; sampling the second communication link to detect a signal corresponding to a second response to the challenge from the transponder; receiving the second response through the second communication link; and authorizing the transponder based on the first and second responses.
