That scenario changed yesterday, though, when United announced that it will now offer customers the ability to scan their passports via their iOS and Android mobile devices when checking in for international flights 24 hours in advance. United said the process and technology works in the same way that a mobile banking app is able to scan and evaluate checks. When checking in for an international flight on the mobile app, passengers will automatically be prompted to scan, aka take a picture of, their passport.
This launch is part of a large testing run, and United said it will collect feedback from users in order to improve and add to the service. If you're headed out of the country via United anytime soon, be sure to give it a go and let us (and United) know if you have any feedback. We're going to try it out next week when we make our way back to the States.
