The Intersect is a computer system designed by Stephen Bartowski which encodes vast amounts of government information, harvested from every intelligence agency in the United States and can store it in a compatible person's subconscious.

Human Intersects instinctively, automatically and flawlessly notice, process and analyze information at incredible speeds. If something triggers the Intersect within them they would receive feedback from the database in the form of flashes. In each case, the flash itself is virtually instantaneous; however, the user experiences brief disorientation as he flashes.

A second intersect, 2.0 could not only show its host flashes of information as in the previous form, but it could supply the host with physical skills, instilling instant comprehensive knowledge of a given subject.
