I was flying through JFK in the past year, JetBlue, and there they had these types of cameras at the boarding area, in addition to TSA. So instead of handing your ticket to the agent, scanning, go on plane, you self scan, there's a picture, and big gates open to let you on. How do you opt out of that?!? Also it was a disaster logistically because the machines were finicky, it moved super slow.

(your face isn't your boarding pass, your face AND your boarding pass is your boarding pass)
