Abstract:
A tamper-detection device and system are disclosed. The tamper-detection device includes one or more components which enable the tamper-detection device to detect a state change, even in the absence of a power supply. A capacitor is provided in the tamper-detection device that, when shorted, discharges and induces a state change at a microcontroller of the tamper-detection device.
