Technology goes way deeper than you ever imagined. And your standard copier, scanner, and printer won't copy money. It won't do it. And I'll tell you why. Other than its totally illegal, of course.

There is a small group of circles on your money, bills obviously, that are an electronic signal to stop the copying of American money. Its called the EURion Constellation.

heathen DID NOT take a picture of american money illegally

And here is the constellation up close, although I haven't outlined it at all, its there.

for the reals though, I didn't do this ever, secret service people

I put a $50 on our company machine and out came a surprise too. Not only did it not copy the money, or any form of it, out came a print out of only a website address.

What happens when someone, not heathen, tries to copy money

At this address you'll find the following:

Every country has legal restrictions on the reproduction of banknote images. The counterfeiting of currency is a crime, and while restrictions vary from country to country, in some countries, any reproduction of banknote images – even for artistic or advertising uses – is strictly forbidden. Even in countries that allow some limited use of banknote images, there are specific rules and requirements. This website will provide you with information about reproducing banknote images and links to country-specific websites for further guidance.
While the overall economic losses to society from counterfeiting of currency are generally limited, the victims who suffer the most harm are individuals and businesses, because no one reimburses those who accept counterfeit notes. Counterfeit currency can also undermine confidence in the payment system, making the public uncertain about accepting cash for transactions.

The Central Bank Counterfeit Deterrence Group (CBCDG) is responsible for this website. A counterfeit deterrence system (CDS) has been developed by the CBCDG to deter the use of personal computers, digital imaging equipment, and software in the counterfeiting of banknotes. The CDS has been voluntarily adopted by hardware and software manufacturers, and prevents personal computers and digital imaging tools from capturing or reproducing the image of a protected banknote. The technology does not have the capacity to track the use of a personal computer or digital imaging tools.

For information specific to a particular country or the banknote image you want to use, click on the appropriate region on the map or select the relevant country or currency from the list.

So kids learn this lesson now, you can't and shouldn't, make fake versions of money because it makes the government very mad. And with technology these days you just know your copiers are all snitches and will call the cops when you do it.
