Personally, I would love to have a card that carried my medical history, credit rating and passport information. However, each holder should be able to choose what information is included. It would be easy to control access to this information by limiting card scanners to only the portion authorized by the holder.
I am sure there are electronic capabilities of which I am not aware. But just think of one small card that could replace drivers licenses, voter registration, medical records, prescription lists, passports, credit cards, game licenses and many more items. Each card could carry one or more of the masses of information we need in a modern society.
