Could facial recognition be the future of airport security? Delta Air Lines is testing it out

Delta Air Lines expects 2.5 million passengers to move through the Atlanta airport during the Thanksgiving period. Ahead of the holiday rush, Delta is testing new facial recognition technology to reduce the time it takes between arriving at the airport and getting passengers in their seats.  

The company's senior vice president for customer experience, Ranjan Goswami, said the facial recognition technology has been years in the making and will speed up travel. 

While major U.S. carriers like United and American Airlines are piloting biometric ID checks at limited airport locations, Delta wants to be the first to offer full curb-to-gate security centered around facial recognition.
