A device for identifying an electrical appliance when it is powered up includes a current detector coupled to an electrical power supply cable of the electrical appliance, for detecting the passage of an electrical current in the cable and generating an electrical signal. A voltage generator converts the electrical signal at the output of the current detector into a direct voltage. An RFID circuit stores identification information, coupled to an antenna suitable for receiving and transmitting signals from and to an RFID reader. The device includes a control circuit coupled to the voltage generator and to the RFID circuit, the control circuit configured for producing a change of impedance of the antenna when the direct voltage is applied, the change of impedance allowing to transmit the identification information to the RFID reader.
