Beginning in the second quarter of 2018, passengers transiting Hong Kong International Airport (HKG) will enjoy an expedited check-in process, thanks to the addition of facial recognition technology. Passengers will only have to present their passport once, at their first point of check-in.  During this initial process, a facial scan will also be performed.  Once this is completed, passengers won’t need to dig out their passport until they reach their destination!  No paper or electronic documentation, including a boarding pass, will be required.  Passengers will pass through security checkpoints and board their flight using only the facial scan that was taken at the first point of check-in.  Hong Kong International Airport handled approximately 70 million passengers in 2016, making it among the world’s busiest, and one of the first airports to fully adopt facial recognition technology.
