Scientists in charge of making U.S. dough are using technology in an attempt to create an “unfakeable” (for now) $100 bill…

Every single American bank note is printed at The Department of The Treasury Bureau of Engraving and Printing facilities, with ink and on paper each made separately, in only one factory in the world. And yet at any given time, there is at least $70 million worth of fake U.S. currency floating around, 75 percent of which is in $100 bills. In large part because of the advent of inexpensive scanners and printers, more and more fake bills are entering circulation: From 1997 to 2007, the amount of passed counterfeit bills nearly doubled, to $64.9 million. Professional fakers are making bills that are more convincing than ever. Take a look at the security flaws in the current $100 bills vs. the technology that will make the next $100 inimitable.

The New $5 Bill

The new $5 bills, which entered circulation on March 13, 2008, are safer, smarter and more secure: safer because they’re harder to fake and easier to check; smarter to stay ahead of savvy counterfeiters; and more secure to protect the integrity of U.S. currency.

In order to stay ahead of counterfeiting, the United States government continues to redesign our paper money. The $5 bill will be followed by a new $100 bill. Redesigned $10, $20 and $50 bills are already in circulation.
