Maybe I do not understand the self scanner/app kiosks but how do they know that the passport entered (or app scanned) belongs to that traveler? I don't consider Waiting for an agent to direct you to a terminal as a security check...

...and I have never held anything over my head after the GE form is printed. I just hand it to the agent collecting the forms and move on...sounds like GE will be pointless soon.

...and sorry for hijacking the thread
