Abstract
Abstract The present invention relates to a document with magnetically detectable anti-forgery and/or anti-fraud means which has the peculiarity of comprising a plate-like element (2), embedding at least one strip (3) constituted by a layer of plastic or aluminum film. The strip (2) supports mutually spaced regions (5,10,20,23,30) obtained with a deposition of magnetic material. The regions (5,10,20,23,30) of magnetic material are readable with a magnetic reading head applicable externally to said plate-like element (2).
