Dri Mark Counterfeit Money Detectors

The U.S. Secret Service estimates that, at any given time, there may be two-hundred million dollars or more of counterfeit money in circulation. Everyday, retailers across the country lose money by accepting counterfeit currency, and the problem is getting worse.

Until about twenty years ago, counterfeiters needed to use expensive, engraved plates and commercial printing equipment to make credible fake money. Now, anyone can make counterfeit bills with a computer, a scanner, and a printer.

In recent years, the government has incorporated security features in U.S. currency to make counterfeiting more difficult; but, this has not stopped counterfeiters who always seem to find a way. What can you do to protect your business?

Dri Mark makes three inexpensive and effective products that can help you to identify counterfeit money before it gets into your cash register. U.S. currency is printed on special paper stock, which is only available to the government. Most counterfeit money is printed on readily-available, non-currency paper. The pen detects authentic currency paper with a quick test. As you can see, a yellow mark appears on this genuine bill. But the mark turns dark on this counterfeit bill, which is printed on common paper stock. Another common method of counterfeiting is called bleaching or washing, where the ink on a genuine small denomination bill is removed with a heavy solvent. The blank currency paper is then reprinted as a larger denomination bill like a fifty or a one-hundred. To detect this type of counterfeit, Dri Mark introduced the Dual Detector. A powerful UV light is combined with a pen for two quick and easy tests. The UV light tests for a UV-sensitive stripe, which is present on all genuine bills, five dollars and up. The security thread in each denomination is in a different color and position on each bill so a beached bill security thread will be in the wrong color and position on the bill. This is a genuine fifty dollar bill. See how the stripe is illuminated by the UV light. The stripe is not present in the counterfeit bill.

For even more security, Dri Mark has introduced the Tri Test Detector. This compact, but powerful, countertop unit combines a more powerful array of UV lights with a pen and another test for verifying the watermark portrait on higher denomination bills. Notice the illumination of the security stripe. And now, with a quick toggle, the watermark portrait on this genuine fifty. Notice the absence of the stripe on this counterfeit. Notice the absence of a watermark on this counterfeit bill. On the front of the unit, this graphic chart shows the location and color of the security stripe for all denominations. The counterfeit detector pen is included in this side slot for an extra level of protection. The Tri Test operates for many months on three “C” batteries, or it can be powered by an optional A/C adaptor. The powerful LED lights last for thousands of hours.

Dri Mark 3513B1 Details

Keep your profits protected with this Dri Mark 3513B1 counterfeit money detector pen! Featuring a special patented formula, this counterfeit pen instantly detects the majority of bad bills, taking the guesswork out of counterfeit money detection. It's easy to use, too!

A light amber mark on the bill means it passes; a black or dark brown mark means the bill is suspect. This counterfeit pen pack contains three markers so you can place them in several key locations or keep extras on hand. When properly capped and stored at room temperature, each pen has a maximum life to mark 25,000 bills. Whether you run a bakery, a restaurant, a market, or a coffee shop, this counterfeit detector pen can help you identify suspect currency to protect your profits.

In the event that fake currency is accepted, the store's deposit will not be accepted by the bank. This makes it vital to catch such an attempt before it is too late. A register with a visible counterfeit detection system is much more likely to deter individuals from attempting to use counterfeit bills. This pen is guaranteed for 1 year but will often last much longer.

    Dri Mark counterfeit pens mark the bills with a yellowish color and then disappear if the bill is real. If it marks the bill black than it is counterfeit. This is a great choice of pack of pens to buy.
    These pens are great to have in-house. You never know when someone will try and pass off a fake bill; no matter what the size.
    Seem to last for a long time during regular use. A very good quality, and a great price point. Ordered multiple and each employee has one of their own.
    These pens are an easy, inexpensive way to reduce counterfeit bills. A quick line on the bill, and you'll have ruled out most counterfeit bills.
