Two of the most common tools used in scanning counterfeit bills are a backlit white light (WM) and an ultraviolet light (UV). The Intelli-Zone Intelli-Count IC100 is a tabletop station used to analyze bills. Simply lay your bill on the surface and turn on one of the two lights. The watermark light can be used to highlight watermark properties found in modern bills. The UV light can be used to illuminate ultraviolet strips found in legitimate currency. This tool, combined with a little knowledge, will help you catch most fake bills. This is a must-have tool for most businesses and retail environments.
