Hong Kong International Airport became one of the first two organisations certified by the International Air Transport Association (IATA) under its One ID digital identity programme on October 28, 2026. The certification covers three key domains: Contactless Travel, Biometric Handling, and Privacy, Consent and Governance, setting global standards for facial recognition and digital identity use in air travel.
The airport has employed facial recognition technology through its Flight Token system, launched in 2021, to expedite passenger departures. Since its introduction, Flight Token has processed over 93 million passengers. More than 80 percent of departing passengers at Hong Kong International Airport
are now eligible to use Flight Token across all airport checkpoints without repeatedly presenting passports or boarding passes.
Industry Recognition and Certification Significance
Vivian Cheung Kar-fay, CEO of Airport Authority Hong Kong, stated that the IATA certification confirms the airport’s digital identity and biometric processes meet global standards. She added that the validation supports expanding Flight Token’s interoperability beyond Hong Kong, establishing a trusted foundation for interoperable digital travel. Nick Careen, IATA’s senior vice-president for operations, safety and security, said the certification represents an industry benchmark and assures passengers and partners of trust in identity verification and data privacy procedures.
Regulatory and Adoption Challenges
Nick Careen acknowledged that adoption
of biometric digital identity technology has been slower than anticipated due to government regulations on data privacy and the physical requirements for identity checks. He cited differences in national regulations as the main barrier to enabling cross-border biometric systems. Regarding geopolitical challenges, including U.S.-China relations, Careen said these would not abruptly halt adoption, noting if the United States chooses not to participate, it would be unfortunate but manageable. He expects U.S. involvement since American travelers also seek smoother journey experiences.
Privacy and Security Perspectives
Francis Fong Po-kiu, honorary president of the Hong Kong Information Technology Federation, remarked that public caution about sharing biometric data
is natural given expectations for maximum border security. He endorsed IATA’s use of decentralized digital identity technology and encrypted tokens, which avoid storing original biometric images and thereby reduce data security risks. Fong suggested the One ID approach could provide stronger privacy protections than typical online applications, though he noted potential cybersecurity risks related to AI-driven threats.
Air New Zealand’s Certification and Cross-Border Trials
Air New Zealand was the other initial recipient of IATA’s One ID certification, recognized specifically for digitalization of passenger admissibility. The airline has conducted trials with Hong Kong International Airport to test the use of cross-border digital identity systems aimed at reducing document
presentation and queuing times at checkpoints, further advancing the framework’s practical applications.
The IATA One ID initiative establishes global standards intended to improve passenger experience by enabling contactless, biometric-enabled processing while ensuring data privacy and passenger consent. The certification for Hong Kong International Airport and Air New Zealand highlights ongoing efforts to overcome regulatory and privacy barriers to wider implementation of digital travel technology.
