Isn't this sort of technology already inside scanners - they recognize dollar bills and resize them slightly so they can't be printed out as 100% replicas? I would have sworn that exists.

To recommend how to best approach the problem, the R&D team first had to learn more about how currency was being counterfeited, then determine ways to prevent it. For example, it's possible to give a scanner the ability to detect when it's scanning a $20 bill. But it's also possible to find a high-quality, printable image of a $20 bill on the Internet, or to take a digital photograph of it, so just blocking the scanner won't totally eliminate counterfeiting.
