See full text

A process for generating an access credential by a communication device may include determining whether a communication device successfully executed a predetermined shutdown sequence when the communication device last transitioned to an inactive state, determining whether the communication device has synchronized with an authorization network subsequent to transitioning back to an active state, and generating the access credential including a timestamp.
