ABSTRACT:
In one embodiment of the present invention, a reading device and a method for determining an identity code is disclosed arranged at a package for a product. At least one embodiment of the present invention is based on capacitive measurements performed in capacitors formed between antennas of the reading device and communication areas of the identity code. The reading device is provided with an antenna or activation element for decoupling or minimizing perturbation signals generated in an electrically conductive foil of the package.
