Singapore's Changi Airport has introduced immigration kiosks that read fingerprints and facial features and double as automated check-in counters, in a bid to cut flight check-in times. The project, known as Fully Automated Seamless Travel or FAST, cuts the time needed for passengers to register for flights and check passports on arrival to from 15 minutes or longer, two minutes.

The system, which began trials in November 2004 at Changi, Asia's sixth-busiest airport, requires users to lodge facial details and thumb prints as biometric data on an identification card the size of a credit card. Passengers insert a card into a kiosk and then look into a camera and press their thumb onto a plate to check their details.
