British Airways is the first airline in the United Kingdom to test the use of biometric technology for international flights, allowing customers participating in the trial to move through the airport “smartly” without needing to present their passport.

Customers who sign up to participate in the airline’s trial at London Heathrow Terminal 5 will be asked to scan their face, passport, and boarding pass on their smartphone or tablet before to their flight. This information will be stored securely.

Smart Bio-Pod cameras authenticate trial participants’ identities in less than three seconds, allowing them to carry their passports in their pockets until they reach their destination.
