Hong Kong International Airport became one of the first two organizations worldwide to receive the International Air Transport Association’s (IATA) One ID certification on October 28, 2026. The certification recognizes the airport’s compliance with global standards in contactless travel, biometric handling, and privacy governance.
Hong Kong’s Flight Token System Usage and Features
The airport’s Flight Token system, launched in 2021, employs facial recognition technology to process passengers at checkpoints. More than 80% of departing passengers at Hong Kong International Airport can use the system to pass through security and boarding without repeatedly presenting travel documents. Since its introduction, over 93 million passengers have gone through checkpoints using Flight
Token.
Officials on Significance and Adoption Challenges
Vivian Cheung Kar-fay, CEO of the Airport Authority Hong Kong, said the certification confirms the airport’s commitment to improving passenger experiences and meeting IATA’s international standards. Nick Careen, IATA senior vice-president for operations, safety and security, highlighted regulatory hurdles slowing broader biometric adoption. He stated that government legislation on data privacy and physical identity verification requirements have delayed the technology’s acceptance. He remarked, “Until governments truly unlock the legislation and regulations required… we are going to have a slow adoption rate, unfortunately. It’s just not moving at the pace we would have liked.” Careen noted differences in national regulations
hamper cross-border interoperability but downplayed geopolitical risks.
Privacy and Security Approaches in One ID
One ID aims to standardize biometric identity usage while enhancing privacy controls for travelers. Francis Fong Po-kiu, honorary president of the Hong Kong Information Technology Federation, acknowledged concerns about biometric data sharing but supported the program’s privacy framework. He explained that One ID uses decentralized digital identity and encrypted tokens, preventing storage of raw biometric images and thus reducing cybersecurity risks. Fong said, “IATA’s explanation makes total technical sense,” though he warned that cybersecurity threats from AI-assisted hacking remain complexities.
Air New Zealand and Industry Context
Air New Zealand is the only other entity awarded IATA’s One ID certification,
recognized for digitalizing admissibility processes that verify passenger entry documents. The airline has conducted trials with Hong Kong International Airport testing the use of digital identity across borders, aiming to reduce document presentation and queue times. IATA’s program faces ongoing challenges tied to varying government regulations on biometric data and physical identity verification, but it intends to improve security and traveler control compared to current systems where airlines share passenger data with governments without the same consent mechanisms.
Key Official Perspectives on Biometric Deployment
Nick Careen said the U.S. government’s participation is uncertain but not mandatory for progress: “If the US decides that they don’t want
to get involved and they don’t want to participate, that’s fine. It would be unfortunate, but it’s fine.” Francis Fong emphasized traveler caution is natural given border security expectations, stating, “People’s caution is totally natural – we expect maximum security at international borders.” Vivian Cheung described the certification as a trusted foundation to expand Flight Token for interoperable digital travel collaboration with airlines and governments.
