Far more effective than a simple pen or UV lamp, the Bishop features systems that check the bill for ultraviolet, magnetic ink and infrared security features to ensure it is authentic US currency.

In addition to counterfeit detection, the Bishop also counts the number of bills that have been scanned and displays the count clearly in the lower right corner of the screen.
