Counterfeit bills cost US businesses millions of dollars every year — and most fake currency is passed at point of sale, where staff are busy and distracted. A reliable counterfeit bill detector is one of the most affordable investments a cash-handling business can make to protect its bottom line.
At Nadex Coins, our counterfeit detectors use industry-standard UV (ultraviolet), MG (magnetic), and IR (infrared) detection technology to identify fake bills quickly and accurately — before they make it into your cash drawer or bank deposit.
How Counterfeit Detection Works
UV Detection — Ultraviolet light reveals the security strip and fluorescent fibers embedded in genuine US currency. Most counterfeit bills fail this test immediately.
MG Detection — Magnetic ink is used in printing authentic US bills. A magnetic sensor detects whether the ink on a note is genuine.
IR Detection — Infrared sensors verify the specific light absorption patterns of authentic bill ink. This layer catches sophisticated counterfeits that can pass UV and MG checks.
Triple-layer detection is the gold standard. If your current detector only uses UV, it may be missing counterfeit bills that more advanced technology would catch.
Who Needs a Counterfeit Detector
Any business that accepts cash is at risk. Retail stores, restaurants, gas stations, bars, entertainment venues, banks, and charity organizations all benefit from having a counterfeit detector at their point of cash acceptance. Even a single undetected fake $100 bill represents a 100% loss on that transaction.
