ENSURE CONTINUED TOP PERFORMANCE To maintain the best possible performance and make sure counterfeit bills stay out of your business, regular cleaning of your bill counter is a must. The longer and more frequently bills are circulated, the more dust and dirt they contain. This grime can impair the operation of your bill counter’s integrated sensors and roller system. By regularly using Safescan’s bill counter cleaning cards, you keep your counter’s internal parts clean, and you can continue to reliably count and check bills’ authenticity.
