Not even needed many times, I was recently at an overseas airport that wanted you to scan your passport to log into the internet. Ya not happening. On another device I downloaded a "sample" passport image of a British passport, the first one on Google images, pointed the phone at the device screen. "This will never work" , he thought as he was immediately logged in. All this stuff really hurts the people who follow the rules the most.

For liveness i suppose you need a good graphics card.

So dystopian
