Well I was recently at a US airport that had automatic "scan your face to board the plane" gates (non-optional) instead of providing boarding pass + passport, so from there to "scan your face to pay" it's a very small leap. They already know all about you and have your biometric identity, what's tacking a payment method to it?

Airport is a very punctual and security specific situation.

Buying things is a benign thing of your day to day life. Scanning your face to pay is a wet dream for surveillance states.

Sorry, I was responding in the original context of GP talking about Newark airport's terrible system. In it, scan your face to pay doesn't seem too far fetched; outside of it, I agree, pretty scary stuff.

So all I have to do to go on an unlimited spending spree is kidnap and lock up one of those hyper realistic mask makers? Nice

Unfortunately kidnapping them is the problem because they're always so well disguised.

What would happen if identical twins wanted to board different flights from the same airport on the same day?

It is most definitely optional
