The systems that allow passengers to fly and cross borders are about to face unprecedented pressure. Global passenger volumes are expected to more than double over the next 25 years.
The encouraging news is that the technology needed to support more seamless and contactless travel is already available or fast approaching maturity. The real challenge now lies in achieving consistent governance, interoperability, and coordinated global implementation. Deploying this technology strategically, inclusively, and on time has been the top priority for delegates at ICAO's ongoing TRIP Symposium in Montréal.
ICAO Digital Travel Credentials (DTCs), biometrics, and secure data-sharing technologies have advanced considerably. Pilot projects and operational deployments already demonstrate their potential to enable seamless travel while maintaining high standards of security and privacy.
ICAO's vision is clear: travelers should be able to use secure, interoperable digital credentials and biometrically enabled verification throughout their journey. This reduces reliance on presenting physical documents while preserving each State's control over identity verification and border decisions.
States stressed that trust and security are never absolute. They must be built on strong evidence-of-identity processes, secure document issuance, and reliable foundational data. Together, ICAO Annex 9 standards, Doc 9303 specifications, and the Public Key Directory (PKD) form the backbone of the global trust framework that supports secure, interoperable travel document verification worldwide.
The hardest problems are not technical but organizational. Governance within and across States remains fragmented. Ministries, border agencies, airports, and IT teams often work at different speeds, use different technical languages, and rarely coordinate from the start. Alignment must begin domestically before extending globally to deliver the seamless experience the sector envisions.
This fragmentation threatens to widen the divide between advanced countries with interoperable e-passport systems and lower-resourced States. It also risks leaving behind vulnerable populations, such as refugees and stateless persons, who are frequently excluded from modern travel infrastructure. Small States and those with limited resources face persistent obstacles when joining global systems or implementing advanced checks, largely due to cost and technical demands. Remote and low-capacity regions, including Pacific Island nations, also face distinct mobility needs.
Rapid modernization heightens the risk of a two-speed world, where some countries or airports fall behind. To ensure progress in every region, airlines, airports, governments, and technology firms must work together.
Security threats are growing in parallel. AI-enabled document fraud and identity spoofing rank among the most pressing concerns. Over time, advances in quantum computing may also challenge the cryptography that underpins both passports and digital identity systems. Participants warned of "harvest now, decrypt later," where data collected today could be decrypted once quantum computers mature. This prompted discussions on adopting post-quantum standards, even as those standards continue to evolve.
Regulatory and privacy constraints add further complexity. In some jurisdictions, for example, remote reading of a passport chip is prohibited.
Cost remains a central concern. Systems that raise operational or end-user costs will struggle to gain widespread adoption among airports, airlines, and travelers. The risk is especially acute when small or remote nations are pushed toward overengineered or unsustainable systems, potentially jeopardizing reliable passport access for their citizens.
Phased modernization gives every State and airport a clear path forward. This approach:
Interoperability will be built into every new system to guarantee future cross-border use. New security features designed to detect AI forgeries will help keep traveler identities trustworthy. And some see the shift to post-quantum cryptography as a genuine opportunity for late adopters to leapfrog directly to future-proofed systems.
