Hong Kong International Airport became the first airport worldwide to obtain the International Air Transport Association’s (IATA) One ID digital identity certification on October 28, 2026. This certification officially recognizes the airport’s implementation of cutting-edge biometric and digital identity technology for passenger processing.
Certification Scope and Technology Systems
The One ID certification awarded by IATA covers three primary domains: contactless travel, biometric handling, and privacy, consent and governance. Hong Kong International Airport utilizes the Flight Token system introduced in 2021, which employs facial recognition technology. This system allows departing passengers to pass through essential airport checkpoints without repeatedly presenting passports or boarding passes.
Flight Token Usage Statistics
According to
Airport Authority Hong Kong, more than 80 percent of departing passengers at the airport qualify to use the Flight Token system across all checkpoint stages. Since its launch, over 93 million passengers have taken advantage of this biometric-enabled streamlined departure process, illustrating significant adoption.
Air New Zealand Certification and Cooperation
Alongside Hong Kong International Airport, Air New Zealand also received IATA One ID certification, specifically for the digitalization of passenger admissibility verification. The airline has worked in collaboration with Hong Kong International Airport, conducting trials to assess cross-border use of digital identity verification to reduce document checks and queue times.
Regulatory Challenges and Data Privacy
Nick Careen, IATA senior vice president
for operations, safety and security, highlighted ongoing challenges in global adoption due to inconsistent government legislation and regulations relating to data privacy and physical identity checks. He said, “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. It’s just not moving at the pace we would have liked.” Careen noted that varying national rules remain a major barrier to biometric system interoperability.
On geopolitical concerns such as the United States’
participation, Careen stated, “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.” He also expressed confidence that demand from American travelers would eventually lead to US involvement.
Francis Fong Po-kiu, honorary president of the Hong Kong Information Technology Federation, addressed privacy concerns regarding biometric data sharing. He said, “People’s caution is totally natural – we expect maximum security at international borders,” adding, “IATA’s explanation makes total technical sense.” Fong emphasized that the use of decentralized digital identity technology and encrypted tokens reduces risks
by minimizing retention of original biometric images.
Airport Authority Commitment and Passenger Benefits
Vivian Cheung Kar-fay, CEO of Airport Authority Hong Kong, said the One ID certification confirms that the airport’s digital identity and biometric processes meet international standards. She commented, “This 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.” The Authority plans to collaborate with airlines and governments to broaden the Flight Token system beyond Hong Kong.
Passengers at Hong Kong International Airport benefit from faster, more secure contactless travel enabled by biometric verification. The system reduces the need
for multiple physical document presentations during airport procedures, improving efficiency and convenience.
