I don't know, but... a system that would allowed me not to carry a bulky wallet filled with an ID card, credit and debit cards, video cards and so on, wouldn't probably be so bad if it was in the shape of some sort of RFID tag.

Then again, the aliens would only need to home in their death lazers at our unique RFIDs and we wouldn't be able to hide.... though decision...



It comes down to the level of trust you put on your government, whichever nation you belong to, and I've never seen a degree of trust toward a government body that would make anyone get tagged like animals. Well, maybe in totalitarian states, where your opinion as the common citizen doesn't amount to anything..
