Are the chips used at security checkpoints to check with your fingerprint/face to verify you are the person in I.D. and not an imposter?
That seems like definitely a benefit to being able to enhance security, but can understand why people wouldn’t want to give that kind of power to a government.
I got a new U.S. passport recently that doesn’t have a computer chip like that I’m aware of, but there is weird wavy text with my name overlaid in the portrait photo for some reason. Heavier plasticky card for the main I.D. page, then there is number with barcode they can scan.
One time I remember an airline accidentally printed the wrong ticket for someone else when I was checking in, but when I got to security checkpoint guard didn’t even notice the name on the ticket wasn’t my name on I.D., neither did I until the flight was about to board and I asked flight crew if that name on the ticket was supposed to be my name, lol.
They were able to print correct ticket for me but that was alarming security guard missed boarding pass was for someone else. Don’t know if mistakes like that happen often at airports, haven’t flown for a long time. That was just a domestic flight not international.
