Paul Griffiths said passports could become redundant within five years because biometric technology can verify identities without physical documents.
Yet travellers still must show passports or other IDs at many points. The main obstacle is linking systems across governments, airlines and airports for a seamless digital journey.
Dubai Airports aims to make passports unnecessary by using biometrics and digital identities. Al Maktoum International Airport will open in 2032 as the world's largest when fully operational; it will use biometrics, facial recognition and other technologies to streamline passenger flow.
Passengers may skip passport checks at immigration thanks to facial-recognition technology. Dubai Airports is working with the General Directorate of Residency and Foreigners Affairs (GDRFA) on these systems, and new screening machinery will let passengers keep laptops and liquids in their bags during security checks.
Griffiths added that a single digital identity could be used throughout a trip—from border crossings to hotel check-ins.
