The idea of a system to uniquely identify people is both scary and comforting. I get mistaken for other people regularly, so I'd like to differentiate. However, I also like my privacy. We need a double-blind way to verify things somehow. Let them verify without details.

As far as banks and VISA. They do make mistakes, but they also have procedures and ideas about security. They get attacked, and maybe if they had to disclose more, we would all have more of an idea what does and does not work. Maybe they could disclose changes after 1 year so we'd know the problems with the old system?

It's a strange balance.

And I agree with blandry. We need to enforce laws, not just make more of them.
