Patent
CA 2360359
The invention concerns a non-contact or a non-contact hybrid smart card, comprising an antenna on a support, said antenna consisting of at least a turn made of electrically conductive ink screen printed on the support, two card body elements (24) on either side of the support, each of the card body elements consisting of at least a plastic layer, and a chip or a module (26) connected to the antenna. The support is made of paper and bears cutouts (22) at each corner whereat are welded together the two card body elements, thereby enabling it, when the card is subjected to folding, to become delaminated at the site where stress loads have been generated by folding, which provides evidence, a posteriori, of a voluntary damaging act, the card preserving the folding trace, and thus provides a countermeasure against fraud.
L'invention concerne une carte à puce, sans contact ou hybride contact - sans contact, comprenant une antenne sur un support, cette antenne étant constituée d'au moins une spire d'encre conductrice sérigraphiée sur le support, deux corps de carte (24) de chaque côté du support, chacun des corps de carte étant constitué d'au moins une couche de matière plastique, et d'une puce ou d'un module (26) connecté à l'entenne. Le support est en papier et possède des découpes (22) à chaque coin au niveau desquelles sont soudés entre eux les deux corps de carte, lui donnant ainsi la capacité, lorsque la carte est soumise à un pliage, de se délaminer à l'endroit où s'exercent les forces de contraintes générées par le pliage, ce qui permet de mettre en évidence, a posteriori, un acte de dégradation volontaire, la carte conservant la trace du pliage, ce qui constitue une parade à la fraude.
