1. A method of using a mobile device carried by a user to control access for the user to a secure area of a facility, wherein the mobile device has a locked state and an unlocked state, and an access control application running on the mobile device that includes a locking mechanism that automatically locks the user out of the access control application after a predetermined time period, after which the access control application must be renewed for subsequent use of the access control application, the method comprising:
the mobile device of the user determining a current location of the mobile device using a location service of the mobile device;
the mobile device of the user determining when the current location of the mobile device is adjacent to an access point of the secure area;
the mobile device of the user determining whether to grant or deny the user passage through the access point and to the secure area including:
the mobile device determining whether the mobile device is in the unlocked state;
the mobile device determining whether the access control application has been locked by the locking mechanism of the access control application;
the mobile device determining to grant the user passage through the access point when the mobile device has been determined to be in the unlocked state and the access control application has been determined to be not locked by the locking mechanism;
the mobile device determining to deny the user passage through the access point when the mobile device has been determined to be in the locked state or the access control application has been determined to be locked by the locking mechanism;
when the mobile device determines to grant the user passage through the access point, the mobile device transmitting an unlock control signal to the access point to unlock the access point and allow passage of the user to the secure area; and
when the mobile device determines to deny the user passage through the access point, the mobile device not transmitting the unlock control signal to unlock the access point, thereby denying passage of the user to the secure area.
