Editing Federal Reserve Note (section)

===Security===
Despite the relatively late addition of color and other anti-[[counterfeiting]] features to U.S. currency, critics hold that it is still a straightforward matter to counterfeit these bills.<ref>{{Cite web|url=https://www.newyorker.com/magazine/2017/09/04/how-the-dollar-stays-dominant|title=Counterfeit|date=August 28, 2017|publisher=NewYorker.com|access-date=June 6, 2018}}</ref> They point out that the ability to reproduce color images is well within the capabilities of modern color [[Computer printer|printers]], most of which are affordable to many consumers. These critics suggest that the Federal Reserve should incorporate [[Holography|holographic]] features, as are used in most other major currencies, such as the [[pound sterling]], [[Canadian dollar]] and [[euro banknotes]], which are more difficult and expensive to forge. Another robust technology, the [[polymer banknote]], was developed for the [[Australian dollar]] and adopted for the [[New Zealand dollar]], [[Romanian leu]], [[Papua New Guinea kina]], [[Canadian dollar]], and other circulating, as well as commemorative, banknotes of a number of other countries. They are said to be more secure, cleaner, and more durable than paper notes, but U.S. banknotes are already designed to be more durable than traditional cotton-based banknotes, seeing as they are 25% linen. One major issue with implementing these or any new counterfeiting countermeasures, however, is that (other than under [[Executive Order 6102]] as well as the demonetization of [[Trade dollar (United States coin)|Trade Dollars]] in 1876<ref>{{Citation |last=United States.

U.S. currency does, however, bear several anti-counterfeiting features. Two of the most critical anti-counterfeiting features of U.S. currency are the paper and the ink. The ink and paper combine to create a distinct texture, particularly as the currency is circulated. The paper and the ink alone have no effect on the value of the dollar until post print. These characteristics can be hard to duplicate without the proper equipment and materials. Furthermore, recent redesigns of the $5, $10, $20, and $50 notes have added [[EURion constellation]] patterns which allows scanning software to recognize banknotes and refuse to scan them.

The differing sizes of other nations' banknotes is a security feature that eliminates one form of counterfeiting to which U.S. currency is prone: Counterfeiters can simply bleach the ink off a low-denomination note, such as a $1 or $5 bill, and reprint it as a higher-value note, such as a $100 bill. To counter this, the U.S. government has included in all $5 and higher denominated notes since the 1990 series a [[security thread]], which is a vertical laminate strip imprinted with denomination information. Under ultraviolet light, the security thread fluoresces a different color for each denomination ($5 note: blue; $10 note: orange; $20 note: green; $50 note: yellow; $100 note: pink).<ref>{{Cite web |title=Security Features |url=http://www.moneyfactory.gov/anticounterfeiting/securityfeatures.html |archive-url=https://web.archive.org/web/20141027033925/http://moneyfactory.gov/anticounterfeiting/securityfeatures.html |archive-date=October 27, 2014 |publisher=The United States Treasury Bureau of Engraving and Printing |access-date=October 27, 2017}}</ref> Additionally the newly designed $100 launched in 2013 has a 3D security ribbon which has proven to be highly resistant to counterfeiting, yet easily understood by the public without special tools or lights.

According to the [[central bank]]s, the number of counterfeited banknotes seized annually is about 10 in one million real bank notes for the [[Banknotes of the Swiss franc|Swiss franc]], 50 in one million for the [[Euro banknotes|Euro]], 100 in one million for United States dollar and 300 in one million for [[Banknotes of the pound sterling|pound sterling]] (old style).<ref>Michel Beuret, [http://www3.unil.ch/wpmu/allezsavoir/les-mysteres-de-la-fausse-monnaie "Les mystères de la fausse monnaie"] {{webarchive |url=https://web.archive.org/web/20131013074050/http://www3.unil.ch/wpmu/allezsavoir/les-mysteres-de-la-fausse-monnaie |date=October 13, 2013 }} ''[[Allez savoir !]]'', no. 50, May 2011 {{in lang|fr}}.</ref>
