Even then, some considered passports to be an “anachronism in the modern world.” But the use of paper passports—which were first digitized as “e-Passports” with NFC chips in 2006—is slowly undergoing one of its biggest transformations to date.

These systems, advocates claim, can reduce the amount of waiting time and “friction” you experience at airports.

In October, officials in Singapore announced that its residents can fly to and from the country without using their documentation, and foreign visitors can “enjoy the convenience of passport-less clearance when they depart Singapore.” More than 1.5 million people have used the systems, officials claim…”
