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.
