Passenger Guide

Flight Token

Flight Token is a self-service biometric identification system that enables passengers to enjoy a seamless departure journey at Hong Kong International Airport (HKIA). With Flight Token, passengers can pass through various departure checkpoints – from check-in and bag drop to security checks and boarding – by simply showing their faces, and without having to present their travel documents and boarding passes again.

Passengers aged 11 or above and holding electronic travel documents can enjoy the Flight Token experience. Starting from Smart Check-in Kiosks, the entire Flight Token journey is currently available for passengers travelling to selected destinations with All Nippon Airways, Cathay Pacific, China Airlines, EVA Air, HK Express, Japan Airlines and Thai Airways. For other passengers, they may register to use Flight Token at the e-Security Gates (see Step 3 below).

                  Step 01

Smart Check-in Kiosks

Departing passengers can create a Flight Token, a biometric token that contains their travel document and boarding pass information, after completing check-in procedures at Smart Check-in Kiosks.


                  Step 02

Self bag Drop

All self bag drop counters are equipped with biometric cameras. Once you have verified your identity by scanning your face with the camera, you can enjoy the self bag drop process by following the guidance given on the touchscreen displays located at counters.


                  Step 03

E-Security Gates

When entering the Airport Restricted Area to board, passengers with registered Flight Token can pass through the e-Security Gates by simply scanning their faces via camera for identity verification. Other passengers can still enrol for a Flight Token by scanning their travel documents and boarding passes at the e-Security Gates to enjoy a faster boarding experience afterwards.


                  Step 04

Flight Token e-Channels

After passing through the e-Security Gates, passengers with Flight Token can complete the immigration departure clearance process by scanning their faces with the cameras at the Immigration Department’s Flight Token e-Channels. This service is currently available for Hong Kong residents holding Hong Kong Special Administrative Region (HKSAR) Passport or HKSAR Document of Identity for Visa Purposes or electronic Home Visit Permit.


                  Step 05

E-Boarding Gates

E-Boarding Gates are available at all departure gates. Board your flight by simply scanning your face with the cameras at the e-Boarding Gates for identity verification. Once your identity is verified, the gate will open automatically.
