Abstract
In an embodiment a device includes an electrically conductive structure, a near field communication (NFC) reader including a support supporting an electrically conductive NFC loop antenna system located in a vicinity of the electrically conductive structure and a component configured to excite the loop antenna system with a current, wherein the loop antenna system has a geometry configured to generate several electromagnetic fields in response to excitation by the current, the electromagnetic fields having a NFC carrier frequency and respective different field directions adapted to induce respective eddy currents cancelling each other in the electrically conductive structure.
