While you can’t ditch your passport just yet, advances in facial recognition technology are slowly but surely making physical identity documents obsolete. Case in point: Two Italian airports, Milan Linate and Catania airports, are currently trialing FaceBoarding, a facial recognition system that allows travelers to go through security checkpoints without having to show their passport or identity card or their boarding pass.

FaceBoarding is a straight-forward process. After checking in for their flights, whether online or at the check-in counter, travelers at these two airports can make their way to the FaceBoarding kiosk where they’ll be prompted to scan they identity document, their boarding pass, and their face.
