Cross X Check and its Founder and Inventors have received three U.S. Patents for the invention of a biometric identifcation system that uses the curvature of the skull to positively identify someone without physical contact utilizing extemely high frequency low power mm-waves. The system allows positive identification even if the person is wearing a hat, scarf, turbin, veil, or burka. The system works in lowlight or no light conditions.

 If a person were holding up a convenience store wearing a ski-mask, a pair of motocycle goggles and a motorcycle helmet or hooded jacket in total darkness, the system will still ID the subject provided he had already been scanned in a prison, DMV, work place, airport, train station or the like.

This system can be made portable and can also detect metal objecta and shoe bombs at the same time, making it perfect for passenger screenings at airports and cruise ships in the future. It could be used at amusement parks to screen pedifiles and at sports arenas and gambling casinos to screen out undesirables who might be wearing a disguise or wig.
