On a trip to the US last week I stopped at the Global Entry kiosk in DFW. Instead of being prompted to insert my passport for a scan. the machine wanted a photo. The system identified me from the photo and knew the flight number of the plane I had arrived on. One more touch and out popped the receipt for exit. Fast but kind of eerie especially because the photo was really bad and yet they found me.
I passed through DFW in January where the passport scan was still in effect so this is new.
