  • Method and device for providing active security to a contact-free electronic device
    Patent number: 8060005
    Abstract: The invention concerns a scrambling electronic device adapted to be magnetically coupled with an inductive element (L3) of a contact-free external communication station (LEC). The scrambling device comprises active scrambling means (DB) adapted, in response to the magnetic field radiated by the external communication station (LEC), to generate a charge modulation capable of causing a collision with the charge modulation generated by the contact-free electronic device (CSC) when the latter is arranged relative to said scrambling electronic device in accordance with a selected relationship, said resulting collision disabling data exchange between the contact-free external communication station (LEC) and the contact-free electronic device (CSC).
