Abstract:
1. A device for protecting an electronic payment terminal, wherein the device comprises: at least one capacitive detector placed between a lower mechanical supporting element of a keypad of said terminal and an upper mechanical supporting element of said keypad of said terminal, said at least one detector having the general shape of a rake with a plurality of teeth and being conformed so that the detector extends between holes of said lower mechanical supporting element and being configured to deliver a reference capacitance; a capacitive measurement microprocessor electrically connected to said at least one capacitive detector, configured to detect a variation of capacitance of said at least one capacitive measurement support; a transmitter configured for transmitting a piece of information representing said capacitive variation, when an absolute value of a difference between said measured capacitance and said reference capacitance exceeds a predetermined threshold.
