Embodiment Construction
[0012] Foreign objects have the potential to damage one or more of the banknote processing components inside the ATM. For example, if two or more banknotes are stapled together, the staples may jam a mechanism that processes the banknotes one at a time. As another example, a rubber band surrounding two or more banknotes may also jam the processing mechanism.
[0013] To detect these foreign objects, the system discussed below may apply pressure to a stack of banknotes. Any foreign object of appreciable thickness, such as a paper clip, staple, or rubber band, can present as an area of relatively high pressure. For example, when a stack of banknotes is under pressure, a staple at the corner of a banknote can create an area of relatively high stress at the corner of the stack.
[0014] In some examples, an ATM may use an array of pressure sensors such as piezoresistive sensors to detect the presence of foreign objects such as staples, paper clips or rubber bands in a stack ...
