SYSTEMS AND METHODS FOR ACCESS CONTROL USING FIELD STRENGTH

摘要

The embodiments described herein include systems and methods for providing controlled accesses to secured devices using near-field communication signals transmitted from a mobile communication device. More specifically, the embodiments described herein determine a measure of a field strength of a near-field communication signal transmitted from a mobile communication device to determine a distance to the mobile communication device, and selectively allow access to the secured device based at least in part on that determined distance. Such a system and method can be implemented using features commonly provided on smart phones and other mobile communication devices, and as such can be used to provide a distance-based controlled access to a secured device without requiring the user to carry a separate key-fob or other specialized hardware.
