Us Currency Security Features and How They Work

The US currency security features are designed to prevent counterfeiting and ensure the authenticity of our money.

The most obvious feature is the portrait of the president or founding father on the bill, which is a great conversation starter, but not a security feature.

Security threads are embedded in the paper to make it difficult to reproduce.

These threads glow pink when held under ultraviolet (UV) light, making it easy to spot a fake.

Watermarks are another feature that's hard to replicate.

The U.S. dollar has a wide range of security features to prevent counterfeiting. These features make it difficult for counterfeiters to reproduce the currency.

One of the key security features is the security thread, which is a passive feature that is difficult to reproduce. The security thread can be detected by examining the quality of the reproduction.

The U.S. currency also features color-shifting ink, which is another security feature. This ink changes color when the note is tilted, making it easier to detect counterfeit notes.

Some of the security features include the kind of paper on which the notes are printed, embedded threads, 3D imagery, microprinting, and watermarks. These features work together to provide a high level of security against counterfeiting.

Here are some of the key security features employed in U.S. currency:

The U.S. dollar is the world's most popular currency and a favorite target for counterfeiters. To combat this, the U.S. government adds sophisticated security features to bills.

Security features include the kind of paper on which the notes are printed, color-shifting ink, embedded threads, 3D imagery, microprinting, and watermarks. These features are carefully integrated into new designs to keep cash safe and secure.

The security thread is an embedded thread running vertically to the left of the portrait that glows pink when illuminated by ultraviolet light. It's visible from both sides of the note and features the letters USA and the numeral 100 in an alternating pattern.

To stay ahead of counterfeiters, the U.S. government conducts more than a decade of research and development, followed by years of optimization and integration testing into the banknote. This ensures the successful deployment of security features into U.S. currency.

Some key security features include three-dimensional images, watermarks, and color-shifting ink, which provide clues as to whether money is fake. These features are woven into the paper, not printed on it, making them harder to replicate.

Here are some of the security features you can look out for:

The serial numbers on US currency are a key security feature. They appear twice on the front of the note, featuring a combination of numbers and letters.

Not all notes have serial numbers with the same level of security. The $100 note, for example, has additional features like a 3-D Security Ribbon and color-shifting Bell in the Inkwell.

Federal Reserve notes are made from a unique blend of materials, consisting of one-fourth linen and three-fourths cotton. This combination provides a durable and long-lasting paper that can withstand the wear and tear of regular use.

You can even spot the presence of security fibers in the paper by looking closely - they're made up of red and blue threads that are woven throughout the bill.

One distinctive feature of the $100 note is its textured surface, which can be felt when you run your finger over it. This is due to the use of recessed intaglio printing, a technique that creates a raised, tactile sensation.

Raised Printing is a distinctive feature of genuine Federal Reserve notes. You can feel it by moving your finger along the note's surface.

The raised printing is a result of intaglio printing, which creates a rough texture. This texture is most noticeable on Ben Franklin's right shoulder, specifically on the left side of the bill.

The rough texture is a result of recessed intaglio printing, which gives the note a unique feel. You can compare this feel to a bill you know is genuine to verify its authenticity.

Older-tech raised printing is felt throughout the rest of the $100 note, giving all genuine notes a distinctive texture. This texture is a key way to identify a genuine note.

Paper is made from a combination of linen and cotton, with the Federal Reserve note paper being one-fourth linen and three-fourths cotton.

The unique blend of materials in paper is designed to provide durability and security, as seen in the Federal Reserve note paper's inclusion of red and blue security fibers.

Counterfeit deterrence is a top priority for the US government, with the Advanced Counterfeit Deterrence (ACD) Steering Committee leading the charge to modernize equipment and incorporate emerging technologies into currency redesign.

The committee is comprised of stakeholders from Treasury, BEP, the Federal Reserve Board, the Federal Reserve System, and the US Secret Service, ensuring a collaborative process across the US Currency Program.

To deter counterfeiting, a number of features are now being used in US currency, including color-shifting ink, embedded threads, 3D imagery, microprinting, and watermarks.

These features are designed to be difficult to reproduce or simulate, making it easier to detect fake bills. The security thread, for example, is a passive feature that's hard to copy, and an aliasing pattern is an active feature that interacts with the reprographic process in a way that makes it obvious on a duplication attempt.

A strong synergistic deterrent effect can be achieved by combining features, such as using color to enhance the effectiveness of moiré patterns.

Detection methods for counterfeit US currency are crucial to prevent financial losses.

The US Treasury's Bureau of Engraving and Printing (BEP) uses advanced technologies to detect counterfeit bills.

Security threads embedded in the paper are nearly impossible to replicate.

These threads glow pink when held under ultraviolet (UV) light.

Microprinting on the bills is another feature that's difficult to fake.

The words "USA TEN" on the $10 bill are an example of microprinting.

The 3D Security Ribbon is a complex feature that's hard to counterfeit.

It features images of 100s and Liberty Bells that shift and change when the bill is tilted.

The $20 bill has a watermark of Andrew Jackson that can be seen from both sides in the light, and a security thread with the words "USA TWENTY" that glows green under ultraviolet light.

The $100 bill features a blue 3D security ribbon with images of bells and the number 100 that appear to move when you tilt the bill.

These features make it easier to spot a fake bill, and can be checked with a combination of touch and sight, as well as a variety of detection devices.

The $100 bill is a hot target for counterfeiters, which is why it was redesigned in 2013 with some added security features. This redesign made it one of the most secure bills in circulation.

The $100 bill features a blue 3D security ribbon woven into the paper, with images of bells and the number 100 that look like they're moving when you tilt the bill. This is a unique feature that's hard to replicate.

To the left of the color-shifting 100 on the front, there's a bell inside of a copper-colored inkwell that looks like it disappears when tilted. This is another clever security measure that helps prevent counterfeiting.

Benjamin Franklin's portrait is on the front of the $100 bill, and Independence Hall is on the back. The bill also uses microprinting in several places, including "THE UNITED STATES OF AMERICA" on Franklin's collar and "USA 100" near the watermark.

A serial number appears twice on the front of the bill, starting with a letter from A to L that corresponds with the regional federal bank that originally distributed the bill. This helps track the bill's origin.

Here are some key security features to look for on the $100 bill:

The $10 bill is tinted with orange, yellow, and red.

This color combination is unique to the $10 bill, making it stand out from other denominations.

The $10 bill features Alexander Hamilton on the front and the U.S. Treasury Building on the back, which is similar to the $5 bill.

A watermark on the right side of the front shows a lighter image of Hamilton when the bill is held up to the light.

The security thread, which runs vertically just to the right of the main Hamilton image, glows orange under ultraviolet light and includes the words “USA TEN” in capital letters.

Microprinting below Hamilton’s portrait includes the words “THE UNITED STATES OF AMERICA” and “TEN DOLLARS USA,” while “USA 10” appears below the image of the torch.

The number 10 on the lower-right corner of the front changes colors from copper to green when you tilt the note 45 degrees.

The $20 bill is a redesign from 2003, featuring security features similar to the $10 bill. Andrew Jackson is prominently displayed on the front, with the White House on the back.

The background colors of the $20 bill are green and peach. A magnifying glass can reveal the microprinting "USA20" along the edge of the text.

The words "TWENTY USA" are printed in blue capital letters in the background to the right of Jackson's portrait. A watermark of Jackson can be seen from both sides in the light.

The security thread on the left of the front has a pattern with the words "USA TWENTY" and glows green under ultraviolet light.

The $50 bill has a unique design featuring Ulysses S. Grant on the front and the U.S. Capitol on the back.

The background colors of the bill are red and blue, and inside some of the blue stars on the left front, you can find the words "FIFTY", "USA", and "50" in capital letters in microprinting.

A security thread runs vertically to the right of Grant's portrait, displaying the words "USA 50" in yellow under ultraviolet light.

You can also see a watermark of Grant's face from both sides of the bill, and the "50" on the bottom right of the front is printed with color-shifting ink.
