This counterfeit money detector pen is your go-to tool for verifying a wide range of international paper currencies, such as US Dollar, Euro, Pound, Yen, Won, Ruble, Cruzior, Pesos, Rand, Peseta, Thai Baht(THB), and Taiwan Dollar(NTD).
Here's how it works: Simply make a small mark like a cross on a light, unprinted section of the banknote. On authentic bills, you'll see a vibrant bright yellow mark, while counterfeit notes will show a distinct dark stain that remains visible. Best of all, the mark will fade away on its own after a few hours. It lets you spot fake cash in mere seconds, making it an essential assistant for cashiers and anyone handling regular cash transactions.
