Samizdata has a debate going on the potential benefits of a National ID card in the UK.  Although I didn't read every word of every comment it appears to me they all missed what I think are the fatal flaws of an ID card.  Some hinted at some of the minor flaws alright.

I really should reword my National ID Card Flaws essay to be similar to my “Just one question” post and be done with that debate as well.
