Abstract
The invention involves a card, including a card body including at least three laminated plastic layers directly superimposed on each other, a second layer being a layer in polyethylene terephthalate glycol placed between a first layer and a third layer, the first layer and third layer being of a chemical nature different from that of said second layer, and an electronic module being incorporated in a cavity of the card body, the module including an integrated circuit, where the thickness of the second layer is of the same order of magnitude as that of the first and third layers, and wherein the cavity extends into the second layer from the first layer.
