> Knowing my mother's maiden name, the history of addresses I've lived at, any of my various ID numbers, account numbers, etc. should not be sufficient to prove identity. What should be, then? I'd like to see a compartmentalized ID that doesn't have all the information there in one easily human-readable (or scannable) form. For instance, a bar only really needs to know if you're of legal drinking age. They shouldn't be able to get your exact date of birth, your address, a copy of your photo, etc.
