(713) 774-1000 New Products COUNTERFEIT PEN DETECTOR Counterfeiters produce Billions of dollars worth of fake currency every year, subsequently costing businesses millions when they try to deposit them in their bank accounts. The paper (actually a fabric) used in most currency cannot be replicated or reproduced, even by the best counterfeiters. ST counterfeit detection pen contains a specially formulated chemical that tests the material used to make the currency in question. Simply mark the bill in question anywhere, and the mark will instantly change color. If the mark turns yellow, the bill is genuine. If the mark turns black or brown, the bill is a counterfeit!
