In the terminals of Hong Kong International Airport, passengers no longer rummage through their bags in search of a passport at every checkpoint: the Flight Token system allows them to complete every stage of departure by face. On 28 October 2026, IATA officially recognized HKIA as the first airport in the world to receive the full One ID certification across three key areas — contactless travel, biometric processing and privacy protection.
The certification was the result of years of work on a system launched back in 2021. More than 93 million passengers have already used it, and today over 80 percent of departing passengers can use it. A passenger confirms their documents in advance via the app, and at the airport it is enough to glance at the camera — and the way is open. This is not merely a convenience but a shift in the very logic of air travel: from paper routine to trust between the airport, airlines and border services.
Behind this lies not only a technological breakthrough but also a complex balance of interests. IATA emphasizes that the One ID standards require strict observance of privacy and passenger consent. In Hong Kong, where data issues always attract particular attention, the airport has passed all checks on consent management and information protection. According to Airport Authority head Vivian Cheung, the certificate confirms compliance with global norms and opens the way to expanding the system beyond the city.
Its fellow awardee — Air New Zealand — shows that the trend extends to airlines as well. Together they are setting a new standard: digital identity is becoming not an experiment but a basic requirement for seamless travel. In an era when passengers are increasingly willing to share biometrics for the sake of speed (according to IATA, 78 percent of those surveyed), Hong Kong demonstrates how this can be done without losing control over data.
For travelers this means fewer queues and less stress, but also new questions about where convenience ends and surveillance begins. For now, HKIA is setting the bar that other hubs in Asia and the world will strive to match.
