Abstract
The invention describes a device () and a method for protecting a self-service terminal against fraudulent installation of spying-out apparatuses for spying-out information, which device and method are based on the detection of metallic components of the spying-out apparatus. The device () comprises a control unit () and a peripheral () which is connected to the control unit () via an interface (). The sound card () has an output for an analog output signal, to which output a coil () for generating a primary electromagnetic field can be connected, and an input for an analog detection signal, to which input a second coil () for detecting a secondary electromagnetic field, which is influenced by the interaction of the primary electromagnetic field with the metallic components of the spying-out apparatus, can be connected. The control unit () actuates the sound card () in order to generate the primary electromagnetic field via the interface () and/or receives the digitized detection signal and analyzes said signal in order to determine whether a foreign metallic object is present.
