For less than £100, and often for free, I could find out where most of you live, your credit record and many other personal details such as shopping habits and many other personal preferences.
All I have to do is to become a registered UK company and sign up to the many organisations who offer these details.
If you hold any sort of personal loyality or credit card (Tesco, Sainsbury down to the smallest) and haven't opted out of their right to sell on your details, then it's a complete doddle to get your details.
Whilst I have no objection to an ID card, if they can't get the driving licence right, or the above, what's the point?
