This research presents a prepaid electric energy consumption system via RFID controlled by Arduino Uno R3. The system is composed of two parts: the prepaid machine and the electric power control machine. The operation of the system uses RFID cards as an intermediary for communication between the prepaid machine and the electric power control machine. However, it is necessary to top up money on the RFID card and to place this card on the electric power control machine to turn on the system to use the electrical appliances. Moreover, the efficiency of the system was tested using five electrical appliances namely: electric fan, incandescent lamp, hair dryer, hot kettle, and steam irons for the duration of 72 hours or three days. The electric power consumption was measured by kilowatt-hour meter compared with the proposed electric power control system. For the experimental results, it was found that the average error of the electric power consumption was at 0.58 %.
