The invention concerns a foldable document comprising a support (10) provided with first and second parts (12, 14) adapted to pivot relative to each other about a folding axis (16) along the edges of (18, 20) of said parts and a non-contact electronic device (1) mounted in the first part (12) of the support and comprising an electronic microcircuit (3) and an antenna (2) electrically connected to said electronic microcircuit (3), and adapted to be (electro)magnetically coupled with an external reading station (5). The quasi-totality of the antenna (2) extends over approximately half of the surface of the first part (12) located proximate the folding axis (16), and the second part (14) is provided with means for disturbing (7) the electromagnetic coupling, arranged substantially perpendicular to the antenna (2) when the first and second parts are substantially superimposed relative to each other, and adapted to disable or enable data exchange externally depending on the angular spacing between the first and second parts.
Folding document including a support (10) having at least first and second portions (12 and 14) adapted to pivot relative to each other about a fold line (16) along edges (18, 20) of said portions and a contactless electronic device (1) mounted in the first portion (12) of the support and including an electronic microcircuit (3) and an antenna (2) electrically connected to said electronic microcircuit and adapted to be (electro)magnetically coupled to an external reading station (5), said electronic microcircuit (3) being adapted to exchange information with the external environment, characterized in that most of the antenna (2) extends over approximately half of the area of the first portion (12) situated in the vicinity of the fold line (16), and in that the second portion (14) is provided with means (7) for disturbing the electromagnetic coupling, disposed substantially in line with the antenna (2) when the first portion (12) and the second portion (14) are substantially superposed one on the other, and adapted to render inoperative or operative the exchange of information with the external environment as a function of the angular offset between the first and second portions (12 and 14).
Folding electronic entity including a support (10) having at least first (12) and second (14) portions adapted to pivot relative to each other about a fold line (16) along edges (18, 20) of said portions and a contactless electronic device (1) mounted in the first portion (12) of the support and including an electronic microcircuit (3) and an antenna (2) electrically connected to that electronic microcircuit (3) and adapted to be (electro)magnetically coupled to an external reading station (5), this electronic microcircuit (3) being adapted to exchange information with the external environment, characterized in that most of the antenna (2) extends over approximately half of the area of the first portion (12) situated in the vicinity of the fold line (16), and in that the second portion (14) is provided with means for disturbing the electromagnetic coupling coupled to said antenna, and disposed substantially in line with the antenna (2) when the first and second portions (12 and 14) are substantially superposed one on the other, and adapted to render the exchange of information with the external environment inoperative or operative as a function of the angular offset between the first and second portions.
Method of controlling exchange of information between a folding document and an external reading station (5), said folding document including a support (10) having at least a first portion (12) and a second portion (14) adapted to pivot relative to each other about a fold line (16) along edges (18, 20) of said portions and a contactless electronic device (1) mounted in the first portion (12) of the support and including an electronic microcircuit (3) and an antenna (2) electrically connected to that electronic microcircuit (3) and adapted to be (electro)magnetically coupled to an external reading station (5), this electronic microcircuit (3) being adapted to exchange information with the external environment, characterized in that provision is made so that most of the antenna (2) extends over approximately half of the area of the first portion (12) situated in the vicinity of the fold line (16), and in that provision is made to equip the second portion (14) with means (7) for disturbing the electromagnetic coupling, disposed substantially in line with the antenna when the first portion and the second portion are substantially superposed one on the other, and in that the attenuation means (7) render the exchange of information with the external environment inoperative or operative as a function of the angular offset between the first and second portions.
