Zusammenfassung:A method for manufacturing flexible printed circuits for smart card modules, wherein a complex material is provided. Said complex material comprises a set of at least two different-coloured strata. Areas (64, 65, 66, 67) of said set are visible through the layer of electrically conductive material (60). Said manufacturing method comprises a step of etching, on a portion of the exposed area (64, 65, 66, 67) of the strata set, at least one of the two different-coloured strata, using a laser beam, so as to render visible the other of the two different-coloured strata. A printed circuit manufactured by said method. A module and a smart card comprising said printed circuit.
