The Dri Mark Flash Test uses three fast, reliable tests to detect counterfeit bills: Detection of the security stripe, the watermark, and an ink sensor.
In a fast-paced retail environment, the feel of genuine US currency may not raise suspicion of a counterfeit. One of the current methods counterfeiters are using is a technique called “bleaching.” In this process, forgers take genuine currency in low denominations, bleach all the ink off of the banknote, and then print higher denomination markings over the genuine linen paper.
The Flash Test gives results in less than a second on the ink sensor, enabling your frontline staff members to make a quick, discreet decision in accepting currency. Further testing of a suspicious bill is available right on the same device with the watermark detector and the UV security stripe detector. The Flash Test’s UV light quickly highlights the security stripe on genuine US currency. Additionally, the powerful LED will quickly reveal the presence — or absence — of the watermark that should appear in all genuine bills.
