Abstract
A method of preventing fraud at a self-service terminal is described. The method comprises: receiving a signal from an electromagnetic sensor located in the vicinity of an electromagnetic signal transmitter; monitoring a drive signal being delivered to the electromagnetic signal transmitter; and comparing the drive signal with the electromagnetic sensor signal. The method then ascertains if a state of the electromagnetic sensor signal is inconsistent with a state of the drive signal; and triggers an alarm when the state of the electromagnetic sensor signal is inconsistent with a state of the drive signal.
