Another problem that has not been addressed yet is what happens when you lose this card. If you lose a bank card, it can be canceled. If you lose your ID card, then what?

First of all, the government are sure as hell not just going to say "oh ok have a new one" or that'd be the world's dumbest loophole open to card cloning. So instead, cue more interviews and more invasion of privacy. It doesn't take too much to imagine you having to be interviewed by a new government agency or the police, in order to establish that you really did lose your card and that you're not a dirty terrorist. Once again, the burden of proof is shifted to you and not the state, who by the very existance of the interview would be implicitly accusing you of attempted fraud.

Secondly, what about the card itself? Sure it'll have an unique identifier which can be revoked (at least I assume it will), but what about the data on it? What happens when - and it would be naive in the extreme to assume that this was a case of "if" not "when" - it is cracked? No encryption in the history of mankind has remained unbroken, and nor do I expect the system used on ID cards to do so. Any information stored on the card, and this will include at the bare minimum your fingerprint and photograph, is then accessible to anyone who wants to use this. ID theft is not a new crime, and this just made it a hell of a lot easier.

You then enter new and dangerous territory. You cannot be issued with a new fingerprint, or a new face. What exactly happens once anyone who gets hold of your card has the ability to pull these details off it? This is a question the government has failed to address, never mind answer.
