Hong Kong International Airport on October 28, 2026, became the first airport globally to receive certification under the International Air Transport Association’s (IATA) One ID digital identity program. The certification confirms the airport’s compliance with global standards for biometric and digital identity-enabled passenger processing.
Flight Token Usage and System Benefits
Since launching the Flight Token facial recognition system in 2021, Hong Kong International Airport has facilitated more than 93 million passengers passing through airport checkpoints without repeated presentation of passports or boarding passes. Flight Token currently serves over 80% of departing passengers at the airport, enabling contactless travel across all checkpoint stages.
Scope of IATA One ID Certification
The One ID certification
awarded to Hong Kong International Airport covers three key areas: contactless travel, biometric handling, and privacy, consent and governance. These categories set international standards for allowing passengers to use biometric data to verify their identity securely and efficiently without redundant document displays.
Challenges in Adoption Cited by IATA
Nick Careen, IATA’s senior vice-president for operations, safety and security, attributed the slower than anticipated adoption of biometric travel technologies primarily to governmental regulations and privacy legislation. He stated, “Until governments truly unlock the legislation and regulations required, not only around data privacy, but also around identification checks and the requirement for that to be done physically …
we are going to have a slow adoption rate, unfortunately.” Careen also flagged differing regulations between countries as a major barrier to cross-border biometric interoperability.
Privacy Concerns and Protections
Francis Fong Po-kiu, honorary president of the Hong Kong Information Technology Federation, commented on public apprehensions regarding biometric data usage at international borders, describing such caution as “totally natural.” He endorsed IATA’s One ID framework for offering stronger privacy protection than many conventional applications, pointing out its decentralized digital identity technology and encrypted tokens that prevent retention of original biometric images.
Fong remarked, “IATA’s explanation makes total technical sense,” while noting that his assessment assumes
ideal implementation conditions.
Vivian Cheung Kar-fay, CEO of Airport Authority Hong Kong, said the certification “affirms our commitment to enhancing the passenger experience through innovation and demonstrates that HKIA’s digital identity and biometric processes meet IATA’s global standards.” She added that the certification provides a foundation for expanding Flight Token beyond Hong Kong to other airports, supporting interoperable digital travel.
Air New Zealand Certification and Industry Context
Alongside Hong Kong International Airport, Air New Zealand also received IATA One ID certification for the digitalisation of admissibility, verifying passenger documentation requirements for destination entry. The airline recently conducted a trial with Hong Kong International Airport to test digital
identity usage in reducing document presentations and queues at checkpoints.
Despite these milestones, the global air travel industry confronts roadblocks around regulations and data privacy that impede widespread rollout of biometric digital identity systems. IATA’s One ID initiative seeks to standardize these systems to allow secure, consent-based sharing of biometric data that passengers control.
