Abstract
Systems and methods for identifying a coded magnetic thread comprise generating a digital representation of the thread and comparing the digital representation with one or more known digital representations; scanning the digital representation to locate a predetermined code sequence; and rotating the digital representation to locate the predetermined code sequence in a predetermined position corresponding to the position of the predetermined code sequence in a stored version of the or each known digital representation prior to carrying out the comparison.
