Abstract: The present invention provides a method of manufacturing an article (9) comprising a fiber layer (5) and at least one electronic chip (7), the fiber layer being formed by depositing fibers on a surface (3) immersed in a dispersion (4) of fiber material.

Abstract: The invention relates to security paper (1) including at least one zone (2; 3) that reacts with nonpolar solvents. The paper also includes a barrier (4) that is impermeable to nonpolar solvents between a first outside face (10) of the security paper and the zone (2; 3) that reacts with the solvents.

Abstract: Paper (1) characterized by the fact that it includes bodies (3) carrying at least one biochemical marker and of sufficient size to be capable of being taken individually.

Abstract: The invention relates to a multilayer structure such as a cover paper for a booklet, in particular a passport. The structure includes a radiofrequency identification device (31, 32) having a chip (31) which is received in the thickness of the multilayer structure without generating extra thickness, the materials constituting the various layers of the multilayer structure are selected, as are the thicknesses of said layers, in such a manner that the cover (20) withstands mechanical and thermal shocks, and in particular is capable of being subjected to graining treatment, and/or to decoration treatment by depositing a film by hot transfer under pressure, and/or to lamination treatment while depositing security films.

Abstract: Apparatus (1) for inspecting an identity document (10) or the like, such as an identity card or a passport, the document having at least one transponder and a code (17), the inspection apparatus being characterized by the fact that it comprises a radiofrequency device (3) serving during an identity check to read and optionally program the transponder (11), at least one code reader (4) adapted to the type of code used by the document, the reader comprising code scanning means and a decoder for processing the scanned data, and data management means (2) enabling the information delivered by the radiofrequency device to be compared with the information delivered by the code reader (4) in order to authenticate the identity document and/or verify that the bearer of the document is indeed the authorized holder thereof, the data management means (2) preferably being arranged to enable the code reader and the radiofrequency device to operate simultaneously.
