Abstract
The present invention discloses a gate control device which controls the passage (e.g., entry, exit, etc.) through a passageway of both authorized persons and unauthorized companions of authorized persons into a protected room. The device may be configured such that the unauthorized companions may be permitted or denied passage if the unauthorized companions are with an authorized person. For example, the device may be configured to allow an entire group of persons to enter a room if only one authorized person is present. In another example, the device may deny passage to the entire group if it contains even one unauthorized person.
