Abstract: The invention relates to an electronic system comprising a casing consisting of at least first and second casing portions and containing a device for detecting the substitution of the first casing portion. The device comprises a first integrated circuit intended to be fixed to the first casing portion and a second integrated circuit intended to be fixed to the second casing portion.
