DEVICE FOR PROTECTING A CONNECTOR AND A COMMUNICATIONS WIRE OF A MEMORY CARD READER

摘要

The invention pertains to a device for protecting an electronic payment terminal comprising an electronic printed circuit board and a casing. According to the invention, said device comprises: - in a volume formed by a first ground plane of said printed circuit and a second ground plane positioned on an internal surface of said casing, at least one capacitive detector configured to deliver a reference capacitance; - a capacitive measurement microprocessor detecting a variation of capacitance of said at least one capacitive detector; - means for transmitting said variation when an absolute value of a difference between said reference capacitance and said measured capacitance exceeds a predetermined threshold.
