I have an ID card...and I'm a slave...

Also I have to ask young people for ID cards when they want to buy alcohol, I will remember all the info and hack it into a secret government database each night because the government...already has it anyway. If you can find any holes in this argument you may keep them.
Also if you got nothing to hide, then you got nothing to fear.
The early bird catches the worm and as the martians say a pound weighs less than a kilogram.

What I don't like a lot is that your cards can be read out from a distance, a piece of paper with text on it or a magnetic chip that can only be read with contact or near-contact sounds like a much better idea to me.
