Abstract (en)
Security document comprising substrate means and at least one electronic security means (2), characterized in that said security document also comprises at least one coil (3) electrically connected to said electronic security means and at least one magnetic means (4). The security document can be manufactured by providing said coil, said magnetic means and said electronic security means on said substrate means. It is particularly useful for checking its authenticity, wherein said magnetic means is moved across the surface of said coil and a status change of said electronic security means is observed.
