Dubai airport will scan your face as you walk through a video tunnel

A lot of passengers come and go through Dubai airports and by 2020, they're expected to play host to some 124 million people. So in an effort to increase the efficiency of security checkpoints, Dubai International Airport is installing a tunnel outfitted with 80 facial recognition and iris scanning cameras, The National reports. The tunnel's walls can display things like virtual aquariums or deserts as well as advertisements and passengers would just have to walk through as they normally would. At the end of the tunnel, a display will either tell the passenger to have a nice trip or will alert officials to take another look. "The tunnel has not come out of nowhere, without any foundation," Obaid Al Hameeri, the deputy director general of Dubai residency and foreign affairs, told The National.
