Imagine a world where you can board an airplane without paper, lines, or even a physical passport. This vision is not far off, as organizations like the United Nations plan to transition completely to a system where facial recognition and smartphones are the primary tools for air travel. According to the International Civil Aviation Organization, the future passenger will download a digital credential directly to their smartphone, which will automatically update in case of delays, facilitating smooth navigation through the airport.
