Abstract
Described are various embodiments of a system for monitoring a physical user presence during an authenticated user access session at an access point. In one embodiment, the system comprises a wireless digital user authentication device (UAD) operable to wirelessly establish the authenticated user access session, periodically communicate an authenticated presence code to actively maintain the session and acquire motion-related data during the session to capture a UAD departure motion representative of the user departing from the access point. The system further comprises a digital application operatively associated with the access point and operable to wirelessly establish the session with the UAD upon arrival at the access point, and periodically receive the authenticated presence code to maintain the authenticated user access session. The authenticated user session is terminated upon identifying the UAD departure motion from said the motion-related data.
