Abstract
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.
