The invention relates to an M2M device comprising a communication unit and a SIM card, the said SIM card comprising a controller or microcontroller (A), characterized in that the SIM card comprises at least one sensor (B; C), the said at least one sensor being a sensor selected from the group consisting of a temperature sensor, a strain sensor, a movement sensor, a displacement sensor, an inertia or acceleration sensor, a sound sensor, a pressure sensor, an impact sensor and a vibration sensor, the said controller or microcontroller (A) comprising an element for deactivating at least some of its functions following the receipt from the said at least one sensor (B,C) of at least one signal indicating that an environment status value is outside a predetermined range, thus preventing the malicious use of the said SIM card.
A machine comprising a communication unit and a Subscriber Identification Module (SIM) card, which SIM card comprises a microcontroller (A), at least one sensor (B;
A method for preventing the malicious use of a Subscriber Identification Module (SIM) card inserted in a communication machine by the prior extraction of the said card from the communication machine device, the SIM card comprising a microcontroller and at least one sensor, wherein the method comprises at least one measurement by a sensor of a signal representing the operating environment of the card, the sending of an alert message reporting an abnormal measurement to a remote server in response to an alert indicative of the signal from the sensor if the signal is located outside a predetermined measurement range and the deactivation of at least some of the functions of the SIM card in response to the receipt of a deactivating message from the remote server.
A Subscriber Identification Module (SIM) card designed to be embedded in a communicating machine, the SIM card comprising a microcontroller, at least one sensor, and an element for deactivating at least some of its functions, wherein the microcontroller comprises a program for sending an alert message reporting an abnormal measurement to a remote server in response to an alert indicative of a signal from the sensor that is located outside a predetermined measurement range, the deactivating element deactivating at least some functions of the controller in response to the receipt of a message deactivating the remote server.
