Recently at Delta gate boarding, they taped a sign about checking passports OVER the face scanner screen, but they CUT OUT holes just for the facial recognition camera so you would not know you were being scanned as you read the sign.

I heard the familiar confirmation beeps as each person read the sign and walked through, facial recognition WITHOUT CONSENT.

This is illegal by the way. I always wear a mask, cap, glasses, and other methods, so it didn’t beep for me.
