A method and system for airport or any other building security where passengers or persons entering a building are caused to undergo a positive identification (ID) check by fingerprint scan, retinal or iris scan, face feature scan, or by any other means of positive identification. A photograph can be taken also. This data, plus the positive ID, and any other optional data about the person, can be checked against government or law enforcement data bases for any government or law enforcement interest in the person. The person can be given an electronic card that can have wireless capability where the person can be tracked while inside the building, airport, or the airspace system. The system can be notified when the person enters any area, secure area, or when a person boards a means for transportation like an aircraft. The system can allow law enforcement to apprehend a person with law enforcement interest at a time and place convenient to law enforcement.
