<p>A credit document (10) connected to a customised document or card (22) is formed of a watermarked paper support (12) with at least one dotted safety coding in linear and cryptographic form on the basis of a key consisting of an individual code. The customised document or card (22) incorporates a microchip for the memorisation of the identification code and of at least one mathematical expression which transcodifies the fingerprint of one or more fingers of the applicant. The equipment for formation of the customised document or card (22), the credit documents (10) and related validation comprises a scanner (28, 38, 38') for taking said fingerprints, compared with those of the owner of the customised document or card (22) upon issuance of the document and during use at the sales points. The watermarked paper support (12) exhibits one or more with copper-plate engraving print reliefs measured by a micrometric sensor (44) integrated in the validation equipment. A customised credit card calls for memorisation of the same parameters transcodified in the related microchip.</p> |
