raising the bar: color copiers

I’m very surprised, but it appears that the new 20 dollar bills are not digitally signed by the treasury. If they can put a serial number on every one they can put a digital signature on them.

That given them more options for asserting a bill was counterfit and make any registry of suspect serial numbers more robust.

People seem to be alergic to digital signing, I wonder why?

The good news is that the lack of a digital signature on the currency will help the use of the currency as a new benchmark for the color copier industry.
