A STATE CONTROL SENSOR ACTIVATING AND/OR DEACTIVATING AN ANTI-FRAUD DEVICE AND A MAGNETIC CARD READER/WRITER FOR AN SST OR AN ATM

摘要

A state control sensor for detecting a foreign object in the vicinity of an SST (Self Service Terminal) or an ATM (Automated Teller Machine) comprising a transmitter transmitting signals to the vicinity of the SST or the ATM and a receiver receiving signals reflecting back from the vicinity of the SST or the ATM for detecting if any change in state occurred in the vicinity of the SST or the ATM, characterized in that the sensor is set to an initial state value by transmitting sonic or ultrasonic wave signals to the vicinity of the SST or the ATM and receiving sonic or ultrasonic wave signals from the vicinity of the SST or the ATM, and when a change in state is detected an anti-fraud device is activated and/or deactivated.
