Abstract
An electronic tag includes an integrated circuit for communicating with an external unit and a detector for detecting at least one physical variable related to the preservation, storage or packaging of a product to which the tag is to be affixed. According to the invention, the detector has an irreversible non-volatile memory for the physical variable or a threshold value thereof. The internal state of the detector being self-modified in the presence of the physical variable or when the physical variable exceeds the threshold value, even in the absence of an electric power source.
