Instantly check a bill's authenticity with the Cassida InstaCheck automatic counterfeit detector. The InstaCheck uses advanced infrared sensors and a comprehensive database of mapped infrared, magnetic and ultraviolet bill markings to verify if cash is legitimate or counterfeit. Verifying the infrared security markings on a bill is a highly reliable anti-counterfeit protection available in paper currency, far more reliable than trying to check for watermarks with a pen or UV light. This compact counterfeit detector has a simple Pass/Fail interface that provides clear, quick feedback on a bill's authenticity. Simply insert the currency in question into the InstaCheck in the direction illustrated on the machine (face up, facing outward). The InstaCheck will handle the rest!
