INFORMATION DEVICE WITH ACCESSORY DEVICE AND TEST METHOD

摘要

The invention relates to a mobile or stationary information device, for example a mobile radio device, a mobile phone, a palmtop, an organizer, a notebook, a notepad or a data bank that are the technical devices most frequently carried along by consumers, that is provided with an accessory device for testing security features that are arranged on and/or in objects to be tested. The device is provided with means for testing the electrical conductivity preferably by capacitative or inductive coupling and/or means for testing the magnetic flux or the magnetization preferably by inductive coupling or Hall effect and/or means for optically testing preferably the optical reference or geometry and/or diffractive structures. The means for optically testing are preferably photodiodes, photoelectric cells, laser diodes, CCD lines, lenses and interferometric sensors. The device and/or the information device detect the security features preferably by capacitative and/or inductive coupling and/or optical testing and/or holographic reconstruction.
