    Abstract: A closed container includes a detection device for detecting opening of or an attempt to open the container. The detection device includes a contactless passive transponder that is configured to communicate with a reader via an antenna using a carrier signal. An integrated circuit of the transponder includes two input terminals connected to the antenna and two output terminals linked by a first electrically conductive wire having a severable part which is severed in the event of an opening of or an attempted opening of the container. A shorting circuit is configured to short-circuit a first output terminal with a first input terminal in the event of a conductive repair of the severed part which forms an electrical connection between the two output terminals.
