Travelers departing from one of the world's busiest airports will soon be able to do so without a passport. Ministers have announced that an automated immigration control system will be implemented at Singapore's Changi Airport from 2024. The changes will allow people to leave the airport without having to “show multiple passes”. Biometric data, derived from fingerprints and facial recognition technology, will replace travel documents and other physical objects, such as passports. The automated immigration lanes at Changi already use this technology, but the new measures will allow people to enjoy a more "seamless" experience when traveling through the airport. Communications Minister Josephine Teo said Singapore would become "one of the first countries in the world" to make such changes. The opening phase of the program is expected to take place early next year with the introduction of QR code scanning stations. The upcoming changes follow amendments to Singapore's immigration laws on Monday, making it easier to use biometric screening at airports and other checkpoints.
