The invention concerns a smart card comprising an antenna (18) on a support made of paper-type fibrous material (12), two card bodies on either side of the support consisting each of at least a plastic layer having a low flow temperature, and an electronic module (26) including a chip connected to the antenna, the assembly formed by the antenna support and the two card bodies being soldered by high pressure hot-process lamination. The fibrous material support comprises at least a recess (14, 16) so that the plastic layers (23, 25) of the card bodies are urged into intimate contact during lamination, the recess forming a weld seam between the card bodies thereby reinforcing the strength of the module.
Carte à puce comprenant une antenne (18) sur un support en matière fibreuse de type papier (12), deux corps de carte de chaque côté du support constitué chacun d'au moins une couche de matière plastique possédant une température de fluidification peu élevée, et un module électronique (26) comprenant une puce connectée à l'antenne, l'ensemble formé par le support d'antenne et les deux corps de carte étant soudés par lamination sous pression à chaud. Le support en matière fibreuse comprend au moins un évidement (14, 16) de sorte que les couches (23, 25) en matière plastique des corps de carte entrent en contact intime lors de la lamination, l'évidement formant une soudure entre les corps de carte renforçant ainsi la tenue du module.
