I just think a lot more work needs to be done. A QR code isn't anything but a string of text which was my original post and correct. I agree with you it can be encrypted, which doesn't make me wrong. Do I think the government of Alberta is encrypting?

We need to know because this will limit societies ability to move and travel. And we can't leave the methodology up to a government that was issuing such a weak passport to begin without QR.

In fact, i'd be willing to bet the QR code from Alberta is just a flash in the pan or a show that is harder to replicate than their first 3 day attempt
