PROTECTION DEVICE, CORRESPONDING METHOD AND COMPUTER SOFTWARE PRODUCT

摘要

A device is provided for protecting an electronic payment terminal, which includes at least one printed circuit and one casing. The device includes at least one capacitive detector having a first part electrically connected to the printed circuit and a second part mounted within the casing of the electronic payment terminal without being electrically connected to the first part. The at least one capacitive detector is configured to deliver a reference capacitance when it is mounted in the electronic payment terminal. The device also includes a capacitive measurement microprocessor electrically connected to the at least one capacitive detector and configured to detect a variation in capacitance of the at least one capacitive detector. The device includes a transmitter for transmitting a piece of information representing the variation in capacitance when an absolute value of a difference between the measured capacitance and the reference capacitance exceeds a predetermined threshold.
