Abstract
A document validator includes a document path along which a document is conveyed and an inductive sensor for sensing features of the document. The sensor has a first inductive element disposed on a first side of a plane of the document path and a second inductive element disposed on a second side of the plane of the document path. Circuitry coupled to an output of the inductive sensor processes signals relating to a determination of at least one of the presence, authenticity and denomination of the inserted document. The sensor need not physically contact a document, such as a banknote, as it is conveyed along the document path.
