Abstract: The present invention relates to a system for tamper detection. A tamper detection system in accordance with an embodiment of the present invention includes: a passive electronic sensor including a circuit having first, second, and third nodes; a load connected between the first and second nodes of the circuit; a friable electrical connection element connected between the second and third nodes of the circuit; and a storage unit, connected to the second node of the circuit, for storing an identification code of the sensor; wherein in use a voltage is applied across the first and third nodes of the circuit, and when the friable electrical connection element is intact, the second node of the circuit is at a first voltage, and when the friable electrical connection element is broken, the second node of the circuit is at a second voltage.
