Abstract
Embodiments of the invention are generally directed to controlling access to an area or enclosed location, wherein any person in possession of a specified RFID badge or other RFID device is defined to be a person who is authorized to be in the area or location. One embodiment, directed to a method, includes the step of detecting the presence of a particular person in the area, who is not in possession of a specified RFID device. In response to detecting the presence of the particular person, a search is initiated to determine whether any authorized person is present in the area. Upon sensing the presence of one or more authorized persons in the area, the method further determines whether any of the sensed authorized persons is accompanying the particular person. In response to determining that no authorized person is accompanying the particular person, prespecified corrective action is initiated with respect to the particular person.
