Abstract: A method and system for securing access to a facility without slowing access by authorized persons in a group or continuous stream of entry. Individuals at the facility are assigned security badges with badge IDs that can be read from a remote reader. A reader is positioned to read a set of security badges within a predefined area relative to an electronically controlled entry barrier that can be engaged or disengaged. The set of detected badge IDs in the area is sent to a computer. The computer determines using one or more predefined rules whether access is permitted for all of the individuals assigned to the detected badges. If all individuals are permitted access, a signal is sent to disengage the barrier. If at least one individual in the set is not permitted access, the barrier remains engaged and an access denied message is sent to a receiver. The access denied message can indicate a condition for denying access such as presence of a specific unauthorized individual in the predefined area.
