Abstract
A device is provided for protecting an electronic payment terminal that includes an electronic printed circuit board and a casing. The device includes at least one capacitive detector in a volume formed by a first ground plane of the printed circuit and a second ground plane positioned on an internal surface of the casing, the at least one capacitive detector being configured to deliver a reference capacitance. A capacitive measurement microprocessor detects a variation of capacitance of the at least one capacitive detector. A transmitter transmits the variation when an absolute value of a difference between the reference capacitance and the measured capacitance exceeds a predetermined threshold.
