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.

Abstract: A contactless transponder includes an autonomous power supply and a non-volatile memory device. In a first mode of operation, an apparatus external to the transponder transmits to the transponder, according to a contactless communication protocol, module command information associated with a module external to the transponder and module data information relating to data to be written to or to be read from the module. The transponder stores the module command information and module data information in a first area of the non-volatile memory device. In response to an activation signal, the transponder autonomously communicates, according to a first communication protocol, with the module by using the module command information and module data information.

Abstract: A first communication interface is a contactless communication interface for an integrated circuit. A second communication interface is coupled to a processing unit external to the integrated circuit. The transfer of data between the first communication interface and the second communication interface is made in a transfer mode using a volatile memory circuit. The volatile memory circuit is accessible simultaneously or virtually simultaneously firstly to processing circuit coupled to said first communication interface and secondly to said processing unit via said second communication interface.
