Zusammenfassung:	Methods for manufacturing a supply item for an imaging device having a helical physical unclonable function are disclosed. The helical physical unclonable function may be used to authenticate a supply item for an imaging device. Measurements of the magnetic field above a helical flight are stored in a non-volatile memory to be used by an imaging device to authenticate the supply item. Other systems and methods are disclosed.
