<p>A credit document (10) is descried joined to a document or client adapted card (22), that is formed by fine paper support (12) with at least a dotted security code in lineal and cryptographic form based on a code consisting of an individual code. The document or client adapted card (22) incorporates a microchip for the memorization of the identification code and of at least a mathematical expression which transcodes the digital print of one or more fingers of the applicant. The equipment for the formation of the document or client adapted card (22), the credit documents (10) and related validation comprises an scanning apparatus (28), (38), (38') for taking the digital prints, compared with those of the owner of the document or client adapted card (22) after the dispatching of the document and during the use in the sale points. The fine paper support (12) shows one or more recorded print reliefs in copper plate measured by means of a micrometric detector (44) integrated in the validation equipment. A client adapted credit card requires the memorization of the same transcoded parameters in the related microchip.</p> |
