Next, the facial recognition in his left eye will verify that I am, indeed, the same guy holding the "END VIETNAM!" sign in my ID. The software compares the ID against a photograph the man secretly took of my face when I first approached him. Thus, although he appears to notice me for the first time while handing back the card, that is just an illusion.
Now that both the ID and the ticket are confirmed legitimate, verifying my identity is as easy as comparing the names.(*Yes, I've actually boarded two planes when the scanner was broken. The tickets were ripped like I was boarding Space Mountain.)
