TAMPER DETECTION BASED ON REMOVAL OF FASTENER FROM RECESS

A point of sale (POS) device includes a flexible member with two exposed conductive areas that are part of a tamper detection circuit. While a recess receives a screw, the screw passes through apertures in the flexible member and in a conductive gasket, and the conductive gasket connects the two exp...

Zusammenfassung:	A point of sale (POS) device includes a flexible member with two exposed conductive areas that are part of a tamper detection circuit. While a recess receives a screw, the screw passes through apertures in the flexible member and in a conductive gasket, and the conductive gasket connects the two exposed conductive areas to one another, closing the tamper detection circuit. Adhesives affix the flexible member to the screw and the conductive gasket to the recess opening so that removing the screw from the recess separates the conductive gasket from the two exposed conductive areas, opening the tamper detection circuit.
