The concept of digital identity in air travel has long been discussed as an inevitable future development. Passengers would move through airports without repeatedly showing passports or boarding passes, with identity verification handled once via biometrics and reused throughout their trip. This vision is now moving beyond pilot projects into practical use.
In the past year, industry tests involving airlines, airports, technology firms, and governments have accelerated significantly. Experts state that the technical groundwork for smooth travel is largely complete. The remaining obstacles involve ensuring systems work together, government policies, and international cooperation.
Younkyung Kim, senior manager for customer experience at the International Air Transport Association (IATA), told reporters that collaboration—spanning airlines, airports, and digital wallet providers—has reached a critical point. “The focus is shifting toward interoperability, government policy and international coordination. We are very close to seeing that mass adoption in one or two years,” she said.
The technology itself is no longer the main barrier. Both IATA and Amadeus agree that the industry’s largest challenge is linking separate systems across borders. “The technology is already there,” said Alessandro Minucci, who leads seamless travel initiatives at Amadeus. “We are in a maturity curve of overall biometric implementation and digital ID at the government level.”
Governments are expanding digital identity frameworks. The European Digital Identity (EUDI) Wallets and government-backed credentials in nations like China, India, and Brazil are broadening access to trusted digital credentials. According to Minucci, the aviation sector has reached what he calls the “last mile” of digital identity maturity, as trusted, government-issued credentials are increasingly available alongside biometric verification.

Global airports test digital identity today
Real-world examples are emerging globally. Amadeus highlights Curaçao’s mobile border processing, Indonesia’s contactless biometric corridors, Manchester Airport’s end-to-end biometric passenger flow, and MSC Cruises’ biometric terminal in Miami as proof that digital identity is no longer experimental. It is now practical and operational.
A key milestone came from IATA’s recent Contactless Travel initiative. The project united airlines, airports, and six digital wallet providers, including Google, Apple, NEC, SITA, Idemia, and IATA’s own wallet, to demonstrate how digital credentials could function seamlessly across the travel process. Unlike earlier tests, this focused on real-world compatibility rather than isolated system checks.
The demonstration confirmed that while the technology operates effectively, refining standards, especially for cross-system compatibility and user experience, remains essential. SITA participated in a Bengaluru Airport trial where passengers used smartphone-stored digital credentials for terminal access, security checks, and boarding. Identity verification began with a passport scan and continued with biometric confirmation throughout the journey, all with passenger consent.
Passenger demand and smartphone integration drive adoption
Governments hold the key to scaling these systems. IATA has identified regulatory coordination as its top priority for the next three years. The shift from theoretical discussions to real-world deployment stems from passenger demand. According to IATA’s global passenger surveys, roughly 80% of travelers would like smartphones to manage more of their travel credentials, while enthusiasm among younger travelers approaches 90%.
Traveler behavior is already adapting. Airlines believe adoption will accelerate if digital identity integrates with existing smartphone wallets, where users already store payment cards, loyalty programs, and tickets. This approach eliminates the need for new apps or behavioral changes, making the transition easier.

However, cross-border trust remains the biggest challenge. Digital identity is only as effective as the confidence in its security and recognition across systems. Stephen Challis, head of passenger flow at SITA Airports, emphasized that “I think it was really positive in the sense that everybody is ready to play and to provide solutions to support the vision.” It must function consistently across countries, institutions, and operational workflows.
Industry confidence has surged in recent years. Kim noted that initial skepticism has given way to concrete progress.
In Europe, the European Entry/Exit System (EES) continues facing operational challenges despite technological readiness. Delays stem from airports integrating the system with existing infrastructure, particularly in busy hubs. Amadeus data indicates that bottlenecks, such as those experienced with EES, result from factors including staffing levels, kiosk placement, enrollment processes, and terminal design. Minucci suggests decentralizing identity verification, such as through mobile pre-registration
Cross-border policies decide digital ID’s future
Government support is now the final critical step. IATA has launched a Global Digital Identity Taskforce to align policies across 193 member states, focusing on mutual recognition of digital credentials. The taskforce aims to create a trusted framework where a credential issued in one country, such as Brazil’s digital ID, can be validated in another without re-verification. Kim of IATA stressed that without cross-border alignment, digital identity risks fragmentation, undermining its effectiveness. Meanwhile, SITA is assisting airports in deploying biometric exit systems, which could streamline departures by eliminating manual passport checks.
The transition to fully digital travel credentials will occur gradually, with physical passports remaining valid until expiration. ICAO estimates that even after governments begin issuing digital credentials, 30% of travelers will continue using passports for at least a decade due to familiarity and regulatory requirements. This overlap ensures a smooth shift, though airlines and airports must maintain dual systems during the transition.
