As you have just used Automated Immigration, you can enjoy the Automated Boarding Gates (ABGs) when departing Singapore today.

Automated Boarding Gates (ABGs)

Automated Boarding Gates (ABGs)
The ABGs in Terminal 4 is a self-clearance option for boarding passengers. Passengers who have used the AIGs on the same day may use ABGs.

Benefit of ABGs
A secure and faster option for boarding clearance.

How to use ABGs

  1. Place your boarding pass on the scanner
  2. Take a photo
  3. Exit the lane

Location of ABGs
All gates at Terminal 4 ('G' gates) are fitted with ABGs. Simply proceed to the assigned gate for your flight during boarding.

No, you will not be able to use the ABGs if you did not use the AIGs on the same day. Please proceed to the counter for boarding.


ABG processes one (1) passenger at a time. Children below 6 years of age are to proceed to the counters for boarding. Children who are aged 6 and above, and have used Automated Immigration on the same day are allowed to use the ABGs. There will be staff to assist children who require help.


During boarding, you will be processed at the boarding counter and assisted to board the aircraft before other passengers.


Passengers who do not wish to use, or are not eligible to use, the ABGs may board through the counters.


ABGs is a self-clearance option where passengers can simply scan their boarding pass for authentication of identity with facial recognition technology. Conventional boarding requires the passengers to hand over their boarding pass and passport to airline staff for face-to-face identity authentication. 


No, you are only required to scan your boarding pass and take a photo to board your flight.


To use the ABGs in future, you would be required to clear Automated Immigration on the same day you depart.
