I'm no genius (watch it!) but I'm sure that the card would be sophisticated enough to only show details pertenant to the card reader being used. ie hospital, police, etc. I understand the Big Brother syndrome and the concerns of some for privacy, but I think these are all things that can be addressed, if and, when such a card becomes a reality. As for your privacy, credit houses, banks, insurance companies and medical labs already have every detail of your personal life. If you collect airmiles, every purchase you've made has been tracked and sorted. They know your driving habits by the amount of gas you purchase, etc. Your lives are already an open book, and not just to the government. Unless you've worked your life on the underground economy and have been paid in nothing but cash under the table, and bartered for everything you have, it's to late. There's already a dossier (or more) on you two inches thick....and it's not owned by the government. Although, I'm sure they have theirs. If you in the CF, your history, and your families, is already on file. Spilt milk and all that.
