Is U.S currency technologicaly advanced or a lagard when compared internationally?

Answer 1

I would say that the US does lag behind technologically in this respect. Compared with Canada and the Euro, for example, the US doesn't use holograms or irridescent designs on banknotes.
Another security feature (which I have heard a rumor that Japan is using this in the newest 10000 Yen notes) is a small chip, .4mm square, which contains an RF id tag in it, embedded in the paper.
The US Bureau of Engraving and Printing would have to do some substantial retooling to include these features.

Answer 2

Seems pretty advanced to me. They have used a special paper with colored fibers in it for a long time. Now there is also color that does not photocopy well, micro-printing which is only readable by a magnifying glass, and which also does not photocopy accurately enough to read, and two or three tricks (including special inks) that they don't tell us much about. What country is doing better? Is a Euro more advanced? Then I'm betting we will pick up on their advances soon.
