One interesting thing, in Arizona to get a "Real ID" drivers license that you can use in for flights, they make you use a face scanning app that runs on your cell phone. So sometimes they're getting the face scan done before you even go to the airport. I wonder if they can scan it at the airport no matter what, and just compare you to previous face scans? Hard to tell when these things actually happen.
