Abstract
A system and method is described for detecting a foreign object such as a skimmer placed adjacent to a bezel for a magnetic card reader device, as used in automatic teller machines and gas pumps. At least two sensors are mounted adjacent to the bezel. Each sensor provides a signal that varies when a skimmer is mounted adjacent to the bezel. A controller receive measurement signals from the sensors, and generates an alarm signal when the measurement signals differ from associated predetermined baseline signals by at least associated predetermined thresholds. The alarm signal indicates that a foreign object has been detected adjacent the bezel. The sensors may be capacitive, time of flight, spectral, radar, and/or inductive. The capacitive sensors may include three or more plates, forming multiple capacitive pairs, each capacitive pair effectively forming a separate sensor.
