To maintain the best possible performance and make sure counterfeit bills stay out of your business, regular cleaning of your counterfeit detector is a must. The longer and more frequently banknotes are circulated, the more dust and dirt they contain. This grime can impair the operation of your counterfeit detector's integrated sensors and roller system. By regularly using Safescan Counterfeit Detector Cleaning Cards, you keep your detector's internal parts clean, and you can continue to reliably check banknotes' authenticity.
