In order to provide a security system, in particular in a motor vehicle (), comprising a transmitter which transmits a signal in the form of an electromagnetic field () and a transportable receiver () which receives the signal and sends back a corresponding response signal to a further receiver, in which it is more difficult to imitate the signal transmitted by the transmitter, it is proposed that a gradient of the electromagnetic field () can be detected by the receiver ().
