Dri Mark Tri Test Counterfeit Bill Detector

Dri Mark Tri Test Counterfeit Bill Detector

Detecting counterfeit U.S. currency is as simple as 1-2-3 with the Dri Mark Tri Test Detector.

Place a bill on the platter and toggle the switch to activate the UV light. Notice how the security stripe is illuminated. Use the guide on the front panel to tell you the proper location and color of the stripe. If the stripe does not appear, the money may be counterfeit.

Then, toggle the switch to activate the white light beneath the platter. The watermark portrait on the right side of the bill is revealed and should look like the portrait in the middle of the bill.

The final test is for authentic paper. Remove the counterfeit detector pen from the side and make a small mark on the money. If it stays yellow or clear, the paper is genuine. But if the mark turns dark, the money is probably counterfeit.

Dri Mark Counterfeit Money Detectors

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.

    Not the best quality but is half the price of the one that we purchased in the past and gets the job done. I would buy another one if needed.
    The great thing about these detection systems is that they are portable so you don't have to worry about plugging it in. They're also convenient for checking I.D.s to prevent under age drinking.
    The city i work in is a tough place. Was always getting fake bills that the markers couldnt detect. Once i got the balck light counterfeit light, we didn’t except one! I love this thing!
    these are fantastic waste your time buying the cheaper one. this is the one you have to have. they free up space on the cash register.
    We were having a problem with counterfeit money in our town and this was easy to use and if I had any doubts about a bill I didn’t except it and never got stuck with a counterfeit bill like others did in town.
    One of the best tools to have to identify counterfeit money. The light allowes you to view the entire bill to make sure you aren't getting robbed
    This is a great counterfeit detector for any establishment that accepts cash in this day and age. With the multiple sure proof methods this is a sure winner. It has saved us on a few occasions. It has already technically paid for itself.
    I have been using the pen for a long time, until counterfeit money makers got smarter. This system not only has a pen on it to check the paper, but also a UV light that let you clearly identify the markers of a real bill.
    This has been a helpful tool. It is great for detecting fake IDs also. The black light detecting correct colored security strips is most helpful feature for bills.
    This device showed up in a beat up box, however it works great. To prevent fake bills in the restaurant. I would recommend this product.
    After receiving a counterfeit $50 a neighboring business asked about out 3-in-1 Counterfeit Bill Detector that we've had for a couple years now. We purchased this for them -- an incredible price that is sure to save you in the long run.
    We use this black light to eat us when we pick crabmeat. The blacklight helps the bones shining really bright makes it easy to pick out.
    We use this nightly and its a very clean sharp looking machine, very light and fits easy with the decor. This is a great buy from WR.
