Stansted Airport passengers are being encouraged to beat the queues and use the new facial recognition gates that have recently been installed.
More than 160,000 passengers have used the gates since the airport began trialling them in December.
The technology, which according to the home secretary will make a faster and more secure route through the border, will be extended to ten other UK airport terminals by August.
Barry McGill, assistant director for the UK Border Agency at Stansted Airport, said all passengers needed to use the gates was a biometric passport.
"If you hold one of the new biometric passports, please take advantage of these gates and help to reduce the time you spend at passport control," he added.
Neale Jouques, head of terminal at Stansted, said they had received positive feedback from customers.
Almost 17 million biometric passports have been issued in the UK since they were introduced in 2006.
Stansted Airport, which is owned by BAA, is the third busiest airport in the UK and serves 22.8 million passengers each year.
