1. A locking mechanism configured to switch from a locked state to an unlocked state when reading an identification code of an identification key that is an authorized code of the locking mechanism, comprising:
a processor configured to read an identification code of an identification key and configured to cause the locking mechanism to switch from the locked state to the unlocked state if the identification code of the identification key is an authorized code of the locking mechanism,
a printed circuit board in a first plane comprising an aperture configured to accept insertion of the identification key according to a first axis secant the printed circuit board through the aperture, the identification key comprising a Near Field Communication passive part, the Near Field Communication passive part of the identification key comprising a wire antenna and a chip connected to the wire antenna and configured to store the identification code,
a Near Field Communication active part comprising a wire antenna positioned on the printed circuit board, the wire antenna comprising a first at least one winding around the aperture, the wire antenna being connected to the processor,
the wire antenna of the Near Field Communication active part is configured to generate a magnetic field when the Near Field Communication active part is provided with energy, thereby providing energy as a result of a relative movement between the passive part and the active part, when the passive part is inserted through the first at least one winding of the wire antenna of the reader to the Near Field Communication passive part of the identification key,
wherein the locking mechanism is configured to establish a Near Field Communication communication between the Near Field Communication active part of the locking mechanism and the Near Field Communication passive part of the identification key when the identification key is inserted into the aperture.
