Abstract
A multi-layer tamper detection arrangement for use with an input device comprising tamper-response electronics and memory. The multi-layer sensor arrangement comprises a flexible circuit assembly configured for connection to the input device. The flexible circuit assembly comprises an outer layer comprising a first tamper-responsive conductor circuit and a first inner layer disposed beneath the outer layer. The first inner layer comprises at least one switch, a removal detection circuit, and a foreign conductor detection circuit. The at least one switch is configured to close the removal detection circuit when the at least one switch is actuated, and the foreign conductor detection circuit is normally open. The first tamper-responsive conductor circuit, the removal detection circuit, and the foreign conductor detection circuit are configured for electrical communication with the tamper-response electronics of the input device.
