Verification of a US currency note occurs in less than one second, with an audible and visual alert notifying the user if the bill passed or failed the analysis. A three year warranty is also included.  The Accubanker D450 Counterfeit Detector is the premier choice in fast, accurate and reliable US currency verification.
