Description

A fast counterfeit detection device that was originally created for 7-11 convenience stores. Stands up to fast paced checkouts. The original patented counterfeit detection pen In 1991, Dri Mark became the original patent holder and only domestic manufacturer of the iconic Counterfeit Detector Pen. Dri Mark continues to set industry standards in counterfeit detection with our full range of detection products. What is the Dri Mark Flash Test Machine? The Dri Mark Flash Test Machine is a portable, battery-operated counterfeit detector that combines UV light, white light, and a magnifier to quickly check multiple security features on U.S. currency. What features does the Flash Test Machine check for in a bill? It checks for the UV security thread, watermark portrait, microprinting, and color-shifting ink—key security features built into genuine U.S. banknotes. How does the UV light in the Flash Test Machine help detect counterfeit money? The UV light reveals the embedded security thread in authentic U.S. bills, which glows a specific color depending on the denomination. Counterfeit bills typically lack this feature or show incorrect placement or color. What is the purpose of the white light and magnifier on the Flash Test Machine? The white light and built-in magnifier help verify watermark images and microprinting—tiny text and faint watermarks that are difficult to replicate in counterfeit currency. Does the Dri Mark Flash Test Machine require an electrical outlet? No, the Flash Test Machine is battery-operated, making it fully portable and convenient for use at cash registers, events, or locations without easy access to power. The Dri Mark Flash Test detects fake bills using ink, watermark, and UV light tests Pen marks dark on fake bills; UV light in cap checks security threads to confirm authenticity. The Dri Mark Flash Test detects fake bills using ink, watermark, and UV light tests.

  • Best Counterfeit Detector On The Market
Size: 0.7" x 2.8" x 4.5"
Finally, a compact triple test counterfeit detector specially designed to be used right at the cash register. I’d give the Flash Test counterfeit detector a 10 star rating if I could. It’s quick and easy to use and requires no cleaning or maintenance. It comes with a plug in power supply so there is never any batteries to change. The Flash Test is smaller than an I-Phone so it easily fits by a cash register without being in the way. I own a busy convenience store and we check every 5 dollar bill and up at the cash register as we get them. In the first week, the Flash Test more than paid for itself by detecting a counterfeit 100 dollar bill. Anyone who owns a retail business should have one of these next to each cash register. The Flash Test was invented by a 7-11 store owner in Las Vegas, Nevada with 32 years of experience. No wonder it's such a great design and works so well. ... show more

  • Best counterfeit detector ever!!!!
Size: 0.7" x 2.8" x 4.5"
Great product, Easy to use. I Vend at a lot of festivals and fairs. Received some fake large bills last year, we even marked it with a counterfeit pen, but the bill still turned yellow. I use it for my food truck also. With this machine, my cashiers are more confident at taking large bills. I work very hard for my money so With all the fake money going around Id rather be safe than sorry. I ended up purchasing four machines. Easy to use, small, very efficient. Haven’t had a problem with it yet. Everything works, Ink detector is loud, UV light turns on and watermark light works. Satisfied with my purchase. Highly recommend if you have a business. ... show more

  • Catch the Scammers
Size: 0.7" x 2.8" x 4.5"
I’ve been very pleased with the performance of this counterfeit detector. From the start, I noticed how compact the design is as it fits neatly on my cashier counter without getting in the way, which is a big plus in a busy environment. The device is also very straightforward to use. It processes bills quickly and checks them in multiple ways, which gives me confidence in its accuracy. I’ve tested it against several bills, and it has been 100% reliable so far. What I particularly appreciate is that, despite its smaller size, the detector offers the same functionality I’ve seen in larger, more expensive units. In fact, it has more testing methods than I expected, which adds another layer of security and peace of mind. The price point makes it a very good value, especially considering the features it includes. The only reason I’ve given it 4 stars instead of 5 is that the build quality, while decent, could feel a little sturdier. That said, it hasn’t affected performance, and overall I consider this an excellent tool for any business that handles cash regularly. ... show more

  • It works outdoors!!!
Size: 0.7" x 2.8" x 4.5"
I ordered two different detectors before this one from Dri Mark. Neither of those two worked when I was vending outdoors. So I returned them and finally found this one. I am so pleased that it works as most of the events I do are outdoors. Its so compact and easy to carry around compared to the others I bought. I already recommended this one to my fellow vendors. ... show more

  • A MUST FOR ANY BUSINESS
Size: 0.7" x 2.8" x 4.5"
I was skeptical since there were so many options online BUT I chose this because it was the most simple, small to place perfectly on the cashier counter (if you own a business you know the possibilities of many objects on the cashier counter) and anyone and I mean ANYONE can use this. This helped my employees to be more comfortable with handling cash and also helps send the message to customer to not mess with us. Thank you 🙏🏻 I never write review but I felt this was worth it. Watch my video as I tried to help out how easy it is to use. I had to watch a YouTube video on this cause the video they had here did not makes sense to me at first. ... show more

Size: 0.7" x 2.8" x 4.5"
So decided to buy this from reading some of those reviews,turn out to be another mistake of my life; opened it, tried it right away, the so call sensor totally BS?! I put $20, $50 didn''t react, put a white piece of paper, didn't react, put an $5.00 bill from ( the wall ) one of those counterfeit we got from an customer, didn't react, ( I did all that by putting those bills facing down, like like the guy mention on his vodeo ), only the blue light worked?! Also the whole thing is so light and cheap design. You guys can order it and see it for yourself. Totally junk. Never buy from this brand again. Returning, ... show more
