STRUCTURE OF PROTECTION ELEMENTS, DEVICE FOR CHECKING DOCUMENTS HAVING SIMILAR PROTECTION ELEMENTS AND METHOD FOR THE APPLICATION OF THE ABOVE PROTECTION ELEMENTS AND A DEVICE

摘要

The structure of the protection elements for documents is supplemented with new protection elements so that their faking would become impossible. The structure of the protection elements for the document subject to checking offers a new design based not so much on the visual check but rather to the method of checking. The design, called functional design, is a combination of electrical conductive and insulated structures having the same or different sizes, on the same or on different planes one against the other, with the same or different electric conductivity. It is made of metallized structures and/or electrical conducting or printing imprints. 18 claims, 15 figures
