India-based carrier, IndiGo, has completed technical trials of a biometric-enabled, contactless international travel process at Bengaluru airport, marking a step towards fully digital passenger journeys.
The trials, conducted at Kempegowda International Airport Bengaluru, were carried out in partnership with the Digi Yatra Foundation, an aviation technology specialist, Bangalore International Airport and the International Air Transport Association. The initiative forms part of IATA’s global programme to test “contactless” international travel using digital identity systems.
The proof-of-concept demonstrated an end-to-end passenger journey, from ticketing and booking management to airport processing, using biometric verification and digital identity, without the need for repeated document checks.
The project builds on earlier domestic deployments in India, where IndiGo and Digi Yatra introduced a self-sovereign identity (SSI) system enabling passengers to use facial recognition and mobile-based credentials to move through airport checkpoints. The latest trials extend that model to international travel, testing its scalability and interoperability with global standards.
Executives said the trials showed that digital identity and biometric technologies could deliver a seamless airport experience while maintaining security and privacy. The system allows passengers to establish their identity in advance and verify it across airport touchpoints using facial recognition, with data shared only on a consent-led basis.
The initiative also aligns with IATA’s “One ID” framework, which aims to standardise digital identity across borders and enable smoother international travel flows.
Bengaluru airport, one of India’s busiest hubs, has been an early adopter of biometric processing through Digi Yatra and is now positioning itself at the forefront of international contactless travel. The airport said the trials are part of a phased strategy to scale biometric-enabled journeys as passenger volumes continue to grow.
IATA said the project highlights India’s growing role in shaping the future of digital travel, with solutions that could be replicated in other markets.
The trials mark an early step towards wider deployment, with further work needed on standardisation and global interoperability before contactless international travel becomes mainstream.
