System for permitting secure access to a restricted area
Abstract:
A wireless device access system employs short-range wireless communication to require the proximity of a user device to a restricted area prior to communicating an unlock request. The access system authenticates the unlock request and the proximity of the user to the restricted area prior to transmitting an unlock command to an access governor. Additionally, the wireless device may require the proximity of a user token prior to operation and/or the access system may include an override within the restricted area blocking any unlock command.
