Manchester Airport in the UK has begun a two-week trial of biometric technology to scan the irises of passengers, as part of an effort to improve security.
Developed by Human Recognition Systems, the Biometrics in Motion trial has begun in Terminal 1 at the airport.
Following check-in, passengers will register for their irises to be checked to identify them at the airport's security search area.
The technology could speed up the identification of passengers and allow international transfer passengers to mix with domestic passengers in the departure lounge before boarding their flight.
Manchester Airport product director Mike Fazackerley said that although it is in the very early stages of development, using this technology for transfer passengers could make Manchester more attractive to airlines as a hub airport in the future.
