Iris-based biometric technology has been rolled out to the last airport in the UK government's program to tighten immigration security.
The Iris Recognition Immigration System (Iris) at Gatwick Airport's South Terminal lets registered passengers enter the UK without queuing to see an immigration officer at passport control.
Air travellers enrolled in the scheme can walk up to an automated barrier, look into a camera and, if the system recognises them, enter the UK.
The biometric technology works by photographing and storing a passenger's iris patterns in a database, along with their passport details and immigration status in the UK.
A one-off enrolment to the Iris system is free and takes about five minutes.
The installation of Iris at Gatwick South completes the rollout of this biometric technology to nine key UK airports - including Birmingham and Manchester airports.
