Studies have shown that there’s one fake bill in every ten thousand bills. This totals to an estimated $147 million worth of counterfeit money currently circulating in the US. If small business owners don’t equip themselves with the knowledge necessary to detect these fake bills, they stand to lose thousands of dollars each year.
In this article, we’ll go over how to detect counterfeit currency so you can decrease the chances of your company accepting fake bills.
Spoiler Alert: Counterfeit pens are unreliable! All the pen does is check for chemicals common in some of the more poorly done counterfeit bills. But, with the rise of digital printing and counterfeiters specifically treating their bills so they will not respond to the pen test, you can no longer rely on the counterfeit pen to protect your retail business.
Instead, you’ll need to know the eight methods that you can use to ensure you’re looking at real money.
How to Detect Counterfeit Money
Counterfeiters can sometimes duplicate one or two security features, but rarely all of them. So, if you check these 8 features on a bill, you should be able to quickly spot a fake. We’ll use a $20 in most of our examples, since that is the most counterfeited denomination.
Here are the 8 things to look for when detecting fake currency:
1. Color shifting Ink
One of the first things to look for when checking to see whether or not a bill is authentic is to see if the bill denomination on the bottom right hand corner has the right color shifting ink. All denominations of $5 or more have this security feature, going back to 1996.
Take this $20 for example, the 20 on the bottom right hand corner will have a copper color when you are looking straight at it. But, if you rotate the top of the bill down so that the bill looks flatter to your eye, it will turn more of a greenish color. See example images below. The left image from a more top-down view is clearly more of a copper color. But, when it is shifted to a flatter plane like the bill on the right, the denomination is much greener.
On the new $100 bills, the inkwell also has color shifting ink, turning green and becoming extra visible when shifted to a flatter visual plane (example shows both copper color and green).
2. Raised Printing
All authentic US reserve notes have raised printing. You can see the difference in in depth on the picture to the right when it is magnified. Many times, counterfeiters have a tough time duplicating this kind of printing method.
To detect raised printing, take your fingernail and run it carefully down the collar/jacket. You should feel an unsmooth texture and some vibration on your nail from the ridges. If not, then you better do an in-depth check on the bill.
3. Blurry Borders, Printing, or Text
If you notice significantly blurry borders, printing, or text, it is an automatic red flag. Authentic bills are extremely detailed, made using die-cut printing plates that are capable of creating impressively fine lines. Printers are rarely capable of the same level of detail. Take a close look, especially at the borders, to see if there are any blurred parts in the bill.
Another thing to be watching for, is micro-printing. Authentic bills have super fine text located at various places on the bill, as shown on the left. Many times, counterfeiters do not have sophisticated enough printing equipment to duplicate micro-printing finely enough to where it is actually readable. If you get a magnifying glass or put the bills under some other form of magnification, you can generally tell pretty quickly whether or not the micro-printing is authentic. If it is unreadable, then it is probably counterfeit.
4. Red and Blue Threads
If you take a close look at an authentic bill (as seen on the right), you will see that there are small red and blue threads woven in and out within the fabric of the bill. Printers try to reproduce this effect by printing red and blue threads onto the bill in a similar pattern. But, a close look will often reveal that such printing is merely surface level, tipping you off to a counterfeit.
The next security feature to look for, is the characteristic watermark. In many of the new bills, the watermark is actually a replica of the face on the bill. In some, it is only an oval spot.
There are several things to keep in mind when examining a watermark.
- The watermark should only be visible when you hold it up to the light
- The watermark should be on the right side of the bill
- If it is a face, the watermark face should exactly match the face on the bill (Sometimes counterfeiters use lower bills and just reprint, in which case the face wouldn’t match)
- If there is no watermark or the watermark is visible without being held up to the light, the bill is most likely a counterfeit
6. Security Thread
The security thread is one of the most distinctive security indicators of an authentic bill.
If you hold any bill up to the light, you will see a security strip on an authentic bill. It will have “USA” and the Bill’s denomination, aka “USA 20” running vertically on the bill.
The ultimate test is to put the bill under a UV or black light and make sure the bill glows the correct color. This extra security measure was originally added to provide a quick way for bar owners (one of the businesses most commonly targeted to dispose of counterfeit bills) to check the legitimacy of a bill.
Here are the location and colors of the security threads on different bills:
- $5 – Right side. Glows blue under UV light
- $10 – Right side. Glows orange under UV light
- $20 – Far left hand side. Glows green under UV light
- $50 – Right around the middle. Glows yellow Under UV light
- $100 – On left side. Glows pink under UV light
7. Security Ribbon (On new $100 only)
The newly printed $100 has an extra security feature. There is a visible blue security ribbon down the right middle of the bill that is 3D. If you move it back and forth, you will actually see the number 100 and a variety of little bells will move from side-to-side as the bill shifts.
8. Serial Numbers should correspond to Printing Year/Series
The last thing to check on a bill, is to make sure the serial number matches the supposed series/run year printed on the bill. Each letter that starts a serial number for a bill corresponds to a specific year (letter to year correspondence detailed below).
Just be sure to check and make sure the series year stated is a correct match with the letter that starts the serial number, and vice versa (shown above).
Here are the letters and the corresponding years/runs they should match with.
- E = 2004
- G = 2004A
- I = 2006
- J = 2009
- L = 2009A
3 Additional Ways to Protect Your Business From Counterfeit Money
While you’ve learned the basics of detecting counterfeit bills, we advise you to take additional precautions to safeguard yourself by taking these steps to provide as much protection as possible for your business.
1. Insure your business against counterfeit money.
In instances of unknowingly accepting fake currencies, you can make claims against any business losses by filing them with your insurance company. Most business insurance policies should be able to protect you from receiving fake currency; however, it is advisable to check with your agent on the coverage of your plan and up to how much they can cover in the event that this happens.
2. Teach your employees to scrutinize every transaction.
Train your employees to be vigilant and meticulous about each transaction by educating them about counterfeit money detection. Remind them to avoid profiling customers and treating everyone critically – scammers are using smart tactics such as making old women, students or well-dressed businessmen perform these fraudulent transactions so that it doesn’t seem obvious and suspicious.
3. If possible, large payments must be deposited directly to the bank or paid via credit cards.
As much as possible, try to promote cashless transactions in your establishment to minimize the risks of accepting fake money. If this is not possible, use simple and reliable counterfeit detecting tools in your business which we will talk about in the next section of the article.
Counterfeit Detection Tools
Education is the main defense against counterfeit bills. But there are also a variety of products available to help you with the counterfeit detection process such as the ones below.
1. Watermark Lamps ($50-$80)
This tool backlights the bill to reveal the discreet and hidden security features of an authentic bill. However, the individual using this tool must be familiar with the security features to be able to identify any irregularities in a bill.
2. Ultraviolet Lamps ($40-$60)
When held up against the lamp’s UV light, the identifying security thread of different bills which we detailed in item #6 above will become much more visible and noticeable.
3. Magnetic Ink Scanners ($30-$50)
These are simple scanners that detect fake or genuine ink on bills.
4. Multi-test Scanners ($180-$260)
This is the most advanced and efficient counterfeiting test machine as it puts bills into multiple tests – a combination of the functions of the tools mentioned above. It is almost impossible for a fake bill to get through this machine. The only downside is its expensive price tag.
What To Do If You Detect a Counterfeit Bill
Let’s say you find a counterfeit bill, what do you do next? Here are several steps to follow to make sure you are processing the bill and alerting the correct authorities.
1. Jot down some notes on who gave you the bill
The police will be sure to want as much information as possible and the more prepared you are, the more information the police will have to aid in their investigation. Jot down things like height, weight, eye color, hair color, and any unique features. A license plate number is great, although that is often not possible.
2. Handle the bill as little as possible and put it in a marked envelope
In some cases, there may be remnants of fingerprints, DNA, or possibly even certain processing chemicals that can help the police tie a bill to a certain counterfeiter. Handle it as little as possible and separate the bill from your other cash by putting it in a marked envelope in the register that you can quickly access later.
3. Fill Out The Secret Service Counterfeit Note Report Form
If you detect or receive counterfeit bills, file an official report by filling out this form from the US Secret Service which requires an individual to detail a suspected fraudulent transaction involving counterfeit money and hand it to the local authorities.
4. Contact Your Local Authorities
After filling out the form or simply reporting a suspected counterfeit transaction, the last step, is to contact your local law enforcement authorities. Just get in-touch with the police station. They will be able to give you further instructions and contact other authorities as needed (generally the Secret Service).
To Sum It All Up
The best answer to fighting currency counterfeiting is education. While there are tools to help businesses detect fake money, they don’t mean anything if there’s a lack of knowledge in spotting them in the first place.
If you educate yourself and your employees on what an authentic bill should look like and the security features it should have, you will be well on your way to detecting counterfeit bills and protecting your business from unnecessary profit loss.
