Abstract
An integrated circuit chip (2), an antenna (3) and a tamper loop (4), and in addition to this, a light emitting diode (LED) (20), configured to be activated, i.e. supplied with current, upon a signal received by the antenna (3). The LED (20) is integrated in the device in such a way that when the LED is activated in the above-described way, the LED lights up so as to become visible by the naked eye, on the condition that the tamper loop (4) is in a predefined state, either open or closed. The LED (20) is coupled between the same terminals (8,9) of the integrated circuit chip (2) as the tamper loop (4).
