The card has a polyethylene terephtalate (PET) core layer (2) with faces on which printed layers (5, 6) of polyvinyl chloride (PVC) extend. The layers are covered by PET protection layers (7, 8). Reinforced connection zones extend across the layer (5) between the layers (2, 7), in the vicinity of intersection of adjacent card edges. Each zone is soldered to a corresponding portion of the layer (2). - An INDEPENDENT CLAIM is also included for a procedure of securing a multilayer card. |
