Abstract: Provided is an assembly that includes a first shield part and a second shield part. The first shield part is foldable on the second shield part. Each of the first shield part and the second shield part includes or is connected to at least one closure element, so that the at least one closure element associated with the first shield part is in contact with at least one corresponding closure element associated with the second shield part. The contact allows ensuring an electrical continuity between the first shield part and the second shield part and generating a Faraday cage. Other embodiments disclosed.

Abstract: A method for producing a radiofrequency device having a first antenna circuit connected to a radiofrequency chip and a second antenna circuit associated with, or coupled to, the first circuit, the method including the following steps: formation of the first antenna circuit in the form of a conductive wire deposited in a guided manner on a first substrate; and formation of the second antenna circuit in the form of a conductive wire deposited on the same first substrate in a guided manner and at a calibrated distance from the first antenna circuit.

Abstract: Method of producing wire inlaid on a support and inlaid wire obtained. The invention relates to an antenna for radiofrequency transponder, said antenna comprising conducting wire portions which are to a major extent inlaid and conducting wire portions which are to a minor extent non-inlaid on a plane support. The antenna is characterized in that said wire portions which are to a minor extent non-inlaid extend over or cross at least one favoured fold line and/or one fold line predefined according to a standardized folding resistance test. The invention also relates to a portable electronic object comprising said antenna and a corresponding method of production.

Abstract: The invention relates to a method for producing a security document, wherein a body is created that comprises two superimposed layers, a circuit which is electric and/or has an electronic chip arranged on the interface between the two layers, and a first adhesive between the two layers, which adheres to the two layers and/or the circuit. The method includes a step of depositing a second adhesive which is different from, or has a different behaviour from, the first adhesive in relation to the solvents or the temperature and partially adheres to at least one of the two layers and/or the circuit.
