RFID Viruses an ID card disaster in the making?

On the face of it this seems to be yet another cause for concern about ID cards as the UK government is trying to develop them -since an RFID tag seems to be part of the specification. The concern is that they could be infected with viruses. Now we should note that this is not something to overplay...

RFID tags could be used as carriers for computer viruses. The reportage on this study has been fairly overblown, a problem exacerbated by the researchers titling their report "Is Your Cat Infected With A Computer Virus?". The real problem is both less frightening and more interesting than these reports suggest.

The report at WC doesn't mention ID cards, but it would appear to me, from the kinds of things suggested by the WC summary, that we have to ask questions about the ability to retain security over a whole population of 60 million when the things are likely, on the government's scenarios, to become a de facto identity marker and the tech to monitor would be all over the place in the hands of, among others, the negligent, the malicious and the criminally inclined...
I'm not sure what might be possible, but monitoring personal info seems possible given the exemplar of phishing on the internet. And that's really scary for what would be a legally sanctioned sole arbiter of identity.
