An inexpensive way to detect counterfeit bills. Counterfeit bills cost businesses millions of dollars every year. Our counterfeit detection pen contains a specially formulated chemical that is safe to use on all bills.
Simply mark the bill anywhere, a black or brown mark means the bill is counterfeit, a clear or slight yellow mark means the bill is genuine. Marks on genuine bills disappear within 24-48 hours.
The pen also works on most foreign currencies in circulation, with the exception of Canadian currency.
