Japan Airlines and Tokyo International Air Terminal Corporation have completed what they describe as the world’s first proof of concept for passenger boarding and international transfer flows that combine digital identity wallets with face biometrics across interconnected airport systems, closing the interoperability gap between departure boarding and carrier-to-carrier transfer re-verification.
The PoC was conducted under IATA’s One ID contactless-travel program and demonstrated that passengers can complete a multi-carrier international itinerary connecting Tokyo Haneda Airport with Hong Kong and onward to European airports without presenting a physical passport or boarding pass at any touchpoint. JAL handled the Haneda segment alongside British Airways. Passengers enrolled in a digital identity system remotely in advance, stored credentials in digital wallets, and underwent biometric verification at departure and transfer gates, with identity data reused seamlessly across carriers. IATA has been steadily building the case that a biometrically-verified passenger can be passed from carrier to carrier without a manual document re-check at each international segment, which is the structural constraint multi-leg journeys hit in practice.
IATA characterizes cross-carrier identity reuse as the core interoperability milestone. The PoC builds on IATA’s April results release, which confirmed that wallet-based biometric digital identity is interoperable across multiple carriers and airports at scale. It extends the earlier Hong Kong-Tokyo digital travel pilot by adding a seamless transfer leg that prior trials did not test. TIAT’s participation as an airport operator, rather than as an airline, is structurally significant: the airport’s involvement signals the kind of infrastructure commitment required for One ID to function at network scale.
Wallet-based digital identity solutions tested across the broader IATA program included Apple Wallet, Google Wallet, Face Express by NEC, the open-source Multipaz wallet, the SITA Wallet, Digi Yatra, and the Air New Zealand Wallet. All PoCs were built using IATA’s One ID standards alongside international frameworks from ISO, OpenID, and the W3C. TIAT’s role as part of the IATA initiative is also supported by IATA’s Contactless Travel Directory, which is designed to connect airlines with biometric-capable airports under the One ID framework.
IATA Director General Willie Walsh said digital identity for international travel “works securely and efficiently” and called on governments to accelerate the issuance and acceptance of Digital Travel Credentials.
