1. An active radio tag configured for attachment to packaging of a product, the active radio tag comprising:
a flat flexible film composite including a carrier layer having a first portion and a second portion, the first portion separated from the second portion by a perforated breaking point defined in the carrier layer;
an integrated circuit applied to the first portion of the carrier layer, the integrated circuit including: a data memory, a transmission unit, a first sensor configured to detect a packaging status of the product, and a second sensor configured to detect an environmental condition;
an electrical conductor arranged on the second portion of the carrier layer, the electrical conductor coupled to the first sensor across the perforated breaking point, the first sensor configured to detect the packaging status of the product based on an interruption in the electrical conductor at the perforated breaking point; and
a unique identifier stored in the data memory;
wherein the radio tag is configured so as to send the unique identifier and status information about the packaging status, via the transmission unit, to a transceiver via a mobile radio network at time intervals.
