Abstract:
1. A point of sale device comprising: a housing; multiple electrically conductive portions located within said housing; a protected enclosure located within said housing; information storage functionality located within said protected enclosure and storing information to be protected information; a capacitance sensor based security system including at least one capacitance sensor operative to sense the capacitance of at least one of at least part of said housing and at least part of said protected enclosure at a reference time and thereafter and to provide an alarm indication of at least a predetermined change in said capacitance sensed by said at least one capacitance sensor, said capacitance sensor being operative to sense displacement of at least some of said multiple electrically conductive portions which are galvanically unconnected with said capacitance sensor, said displacement being the result of tampering with at least one of said housing and said protected enclosure.
