According to IATA, the trials showed that passengers can complete an entire journey, which included transfers, without presenting a physical passport or boarding pass. The tests demonstrated interoperability across borders and between different digital ID systems, which is crucial to international travel and feasibility. Participants successfully used a mix of identity wallets including Apple Wallet’s digital ID for U.S. passport holders, Google ID Pass for UK and U.S. travellers, and India’s Digi Yatra programme. Travellers were able to share identity data securely in advance, enabling pre‑travel checks and reducing repeated document inspections at the airport.
