摘要：The invention relates to portable cards containing integrated circuits, moregenerally known under the name of smart cards. In order to avoid disturbances of theoperation of smart cards due to modifications of threshold voltage of the transistors ofthe circuit under the effect of electrostatic charges, the present invention proposes tocover the surface of the chips with a film of a conductive substance, which film isconnected to a reference potential.
