E-document comprising an electromagnetic interference element

摘要

A laminated structure for an E-document, comprising a first support layer defining at least two flat flaps connected by at least one fold line, the first flap supporting an antenna and a microcircuit device enabling contactless data exchange, the second flap supporting an electromagnetic interference element arranged in relation to the microcircuit device so as to be able to oppose contactless reading and/or writing of the microcircuit device in at least one folded configuration of the structure, the structure having at least one heat-activated or pressure-sensitive adhesive layer making it possible to receive the microcircuit device and/or the antenna and/or the electromagnetic interference element at least in part in its thickness, and/or the flaps having at least one layer of an adhesive and/or a fibrous layer and/or a polymer layer having a different thickness for each of the flaps.

1. A laminated structure for E-document, the structure being mounted between pages of the E-document and a cover of the E-document, the structure comprising a first support layer defining at least two flat flaps connected by at least one fold line:
the first flap supporting an antenna and a microcircuit device enabling contactless data exchange, the second flap supporting an electromagnetic interference element arranged in relation to the microcircuit device so as to be able to oppose at least one of contactless reading and contactless writing of the microcircuit device in at least one folded configuration of the structure, wherein the structure comprises at least one heat-actiyated or pressure-sensitive adhesive layer making it possible to receive the microcircuit device and/or the antenna and/or the electromagnetic interference element at least in part in its thickness, and at least one of :
at least one fibrous layer, anda polymer layer, the at least one fibrous layer or polymer layer comprising second and third support layers, supported by the first flap and second flap, respectively, wherein the second and third support layers have different thicknesses for each of the flaps, the antenna being located between the first and the second support layers, and the electromagnetic interference element being located between the first and the third support layers.
