Abstract
The invention discloses a security foil which covers a security module, wherein the security foil comprises a shielding from electromagnetic radiation from inside and outside. In a preferred embodiment the security foil comprises a metal lattice with defined lattice distances. The lattice distances can be used to change characteristics of the shielding from electromagnetic radiation, in particular the relevant spectra. The invention is especially applicable in electronic payment transactions. The invention permits effective and low-cost shielding of security modules against electromagnetic radiation from inside and outside. Additional time and labor is saved because existing components can be used.
