Cellular telephone based electronic access control system

摘要

A system and method for cellular telephone based electronic access control (EAC) of secured portals is depicted. The EAC system determines whether access to any particular secured portal is to be granted to a user based on the relative geographic positions of the secured portal and the user's cellular telephone. If the cellular telephone is within a configurable radius of the secured portal, the EAC system checks its database to determine whether the user of the cellular telephone has been granted access privileges to the secured portal. If the user has been granted access privileges, the EAC system electronically unlocks the secured portal.
