Abstract: A system and method for providing authenticated access for a user to a restricted physical space via a mobile device is described. The system employs a smartphone application, which facilitates a user's reservation of a selected seat and space within a shared space. The shared space is equipped with a lock interfaced with a secured server, which is configured to unlock upon an authenticated request for entry by a user with a reservation. Biometric and/or pin authenticated means of entry are provided via the application as well as a pin pad disposed on a control module. Sensors disposed in or near the seats available for reservation are configured to detect a human presence employing the reserved space, which confirm the presence of a user, and monitor unauthorized use. A timeclock of the server records the duration of time spent within the shared space, and bills users accordingly.
