Abstract
This disclosure provides methods, systems, and devices for communication of authentication information in an access control system. The authentication information may be transmitted to an electronic locking device configured to restrict access to an entry point of the access control system. In various embodiments, a smart device comprises a light-emitting diode (LED) and a wireless networking radio for exchanging access control information with a remote server. The smart device may receive information from the remote server that configures the LED to present authentication information as an optical signal. The electronic locking device may comprise a photodetector arranged to confront a user holding the smart device so as to receive an optical signal emitted by the smart device. According to various embodiments, the electronic locking device may be configured to respond to the authentication information conveyed by the optical signal by unlocking the entry point.
