A method and device for evaluating currency bills using a strapping unit that allows a currency evaluating device to automatically strap stacks of currency bills. Currency bills are placed in an input receptacle and an evaluating unit processes each currency bill one at a time. The currency bills are then transported to a plurality of output receptacles. A stack moving mechanism transports a stack of currency bills, which contains a predetermined number of currency bills, from each of the plurality of output receptacles to the strapping unit or a strapping position. Each stack of currency bills is strapped using strapping material.
