Starting in 2024, officials say Singapore’s Changi Airport will introduce automated immigration clearance, which will allow passengers to depart the city-state without passports, using only biometric data. “Singapore will be one of the first few countries in the world to introduce automated, passport-free immigration clearance,” Communications Minister Josephine Teo announced during a parliament session. Often ranked the world’s best airport and also one of the busiest, Singapore’s Changi Airport serves more than 100 airlines that fly to 400 cities in around 100 countries and territories worldwide.
