Perco Counterfeit Money Detector Pen (2 Pack)

The Perco Counterfeit Money Detector Pen (2 Pack) is a security tool designed for quick authentication of paper currency. Each pen contains an iodine-based solution that reacts with the starch present in wood-based paper commonly used for counterfeiting. To use, simply make a small mark on the surface of a bill; a dark or brownish-black mark indicates the bill is likely counterfeit, while a light yellow or amber mark suggests the currency is genuine and printed on the correct cellulose-based paper used by central banks. This two-pack provides backup or allows for placement at multiple registers. The pens are suitable for use in any business that handles cash transactions, including retail stores, restaurants, flea markets, and event venues. They offer a quick, non-destructive method for frontline counterfeit detection.
