The invention concerns a method for making a non-contact smart card and more particularly a method for making a non-contact card whereof the antenna is on a support made of fibrous material such as paper. Said method comprises a step which consists in producing the antenna by screen printing on the support; a step which consists in bonding the chip contacts on the antenna support with a conductive adhesive; a step which consists in laminating card elements by hot pressing on the antenna support. Cutouts produced in the corners of the antenna support before the laminating step enable to weld together the card elements. The resulting card thus enables to visually observe a posteriori harmful mechanical stresses (extreme bending) to which it is subjected.

La présente invention concerne un procédé de fabrication d'une carte à puce sans contact et plus particulièrement un procédé de fabrication d'une carte à puce sans contact dont l'antenne est sur un support en matériau fibreux tel que le papier. Ce procédé comprend une étape de réalisation de l'antenne par sérigraphie sur le support, une étape de collage des contacts de la puce sur le support antenne avec une colle conductrice, une étape de lamination des corps de carte par pressage à chaud sur le support de l'antenne. Des découpes réalisées dans les coins du support de l'antenne avant l'étape de lamination permettent une soudure des corps de carte entre eux. La carte ainsi obtenue permet de visualiser a posteriori les mauvais traitements mécaniques qui lui sont infligés (flexions extrêmes).
