发明名称 Electromagnetic compatibility (EMC) safety foil for detecting intrusion into security module e.g. of electronic cash facility
摘要 The protecting foil (1) is made of flexible material, with an inlay of conductors (100) electrically connected together and of copper. The inlay can be lattice-shaped, having a certain distance between the conductors. The foil is of one piece and continuous but provided with gaps for equipment. The foil has contacts (120), so that it can be earthed, and it should be tinned to prevent oxidation. Earthing passes to earth all electromagnetic signals and energy, effectively screening the zone inside the foil from this type of manipulation.
