摘要：

A security system for testing for exposure of the contents (4) of a container (3) to a predetermined physical stimulus. The system has a sensor (1), for example a pressure sensor, and a tag (2) in the form of a r.f. transponder which are both placed within the container (3). The transponder transmits data representative of the ouptut state of the sensor (1) in response to an interrogation signal for a transceiver (5) outside the container (3), without the container having to be opened.
