I found the VisionAccess 3D Face Reader by Bioscrypt, really cool. A Face Recognition System, the 3D Face Reader can read and authenticate a face in less than one second. All you need to do is stand in front of it and the 3D scanner kicks in!

"The reader is used for strengthening security at corporate buildings, banks, hospitals, airports and other types of entry points for the commercial and Civil ID markets."
