The only thing I don't like about ID cards is that it's yet another proof of identity one has to carry. I'd like the ID card to replace all other forms of ID such as Passport, driving Licence etc. It shouldn't be too much of a problem technically. Other than that, I really don't see what the fuss is about. To those people who object to carrying ID cards, I'd like to ask what they have to hide? I agree with some of the others here who've said just convenient it can be.
