A smart card including an antenna (18) on a support made of paper type
fibrous material (12), two card bodies on each side of the support each
consisting of at least one layer of plastic material having a low flow
temperature, and an electronic module (26) featuring a chip connected to
the antenna, the assembly made up of the antenna support and the two card
bodies being welded together by hot-lamination under pressure. The support
made of fibrous material includes at least one opening (14, 16) such that
the plastic layers (23, 25) of the card body come into near perfect
contact during the lamination operation, the opening forming a weld
between the card bodies thus reinforcing the connection of the module.
