Abstract: A smart radio frequency identification (RFID) system for controlling operation of electrical units is disclosed. The system includes a RFID tag, a control unit coupled to the RFID tag, a relay unit connected to the control unit and to the electrical unit, and an external RFID reader for generating radio frequency (RF) signals for sending data to the RFID tag when the RFID reader is placed next to the RFID tag. The RFID tag checks and stores the data and passes the data along to the control unit. The control unit sends a control signal to the relay unit in accordance with instructions contained in the data, causing the relay unit to operate the electrical unit between a first state and a second state. The system may also include sensors to monitor certain conditions of the electrical unit and cause the control unit to turn off the electrical unit when the conditions are abnormal.
