Contactless immigration system at Changi Airport T4

The trial began on Nov 25 and is open only to Singapore citizens aged six and above holding passport numbers beginning with the letter "K", and whose passports were issued after Jan 1, 2018.

The Immigration and Checkpoints Authority (ICA), which is running the trial, said travellers using the contactless immigration clearance lane should remove sunglasses, caps or other headgear that could obstruct their eyes or face when passing through the lanes.
