Abstract
An electrical device includes an electrical cable and a connector coupled to the electrical cable. The connector is configured to receive electrical current from an external power source. The connector includes an RFID tag, and an electrical storing device configured to store electrical energy from the external power source and provide electrical energy to the RFID tag when the connector is disconnected from the external power source. The RFID tag transmits a signal independent of the connector being coupled to the external power source.
