Abstract
A proximity lock is battery powered and includes an infrared (IR) circuit for detecting the presence of an authentication device and a radio frequency (RF) circuit for communicating with the authentication device. RF signals emitted from an RF circuit are received by an antenna within the authentication device. An IR signal recognizes the presence of the authentication device and prompts the RF circuit to communicate with the authentication device.
