Since 16 December 2004, the Immigration Department has introduced the automated passenger clearance system (e-channels) to members of the public. Currently, Hong Kong permanent residents (except those under the age of 11) or Hong Kong residents holding Document of Identity for Visa Purposes (DI) can use their smart identity cards to perform self-service immigration clearance. Since 12 September 2006, e-Channel service has been extended to people who have the right to land or are on unconditional stay in Hong Kong, and non-permanent residents who have been issued with a notification label. Meanwhile, please note that Hong Kong residents must bring along with them their valid travel documents when travelling.
To enter the e-channel is simple. People just have to insert their smart identity cards with the side bearing the arrow and chip into the card reader. The system will take a while to perform mutual authentication with the smart identity card key. People can enter the e-channel when the gate doors open. After entering the e-channel, people just need to place their thumbs flat on the centre of scanners. After fingerprint verification they can leave the e-channel.
