Because I'm a "furriner" here (born and bred in the land of the rising haggis) I have a paper ID card too.
What info does that carry apart fom my name and address and a photo? Hell, my Belgian driving licence is only a piece of paper with my photo on it.
But some of us have been used to carying passports with us (I used to work at LHR, doing all kinds of 'leccy stuff, you might have heard me swearing) and when I go on vacation, I carry my UK passport. When I am here in België, I always cary my UK (biometric) passport and ID card. Nobody will dispute who I am, and if I am pulled over (again) for an ID check, which notrmally happens after *ahem* beers, it's only a minor inonvnience.
BUT... An ID card should only be that. Something that says who you are and no more
