Abstract
A device is provided for protecting an electronic payment terminal. The device includes at least one capacitive detector placed between a lower mechanical supporting element of a keypad of the terminal and an upper mechanical supporting element of the keypad of the terminal. The at least one detector is configured to deliver a reference capacitance. A capacitive measurement microprocessor is electrically connected to the at least one capacitive detector and configured to detect a variation of capacitance of the at least one capacitive measurement support. A transmitter is configured for transmitting a piece of information representing the capacitive variation, when an absolute value of a difference between the measured capacitance and the reference capacitance exceeds a predetermined threshold. The capacitive detector is conformed so that it extends between holes of the lower mechanical supporting element.
