A charging system using an RFID tag is provided to improve convenience of a user by enabling a user to charge an object by simply placing the object to the RF field. A charging system using an RFID(Radio Frequency IDentification) tag includes a main body(100) and a reader(200). The main body uses the RFID tag to communicate with external devices and includes an RF communication unit(150) which converts the energy from a communication signal to a current. The reader includes an RF communication unit(250) which wirelessly interfaces with a communication port of the external device and the RF communication unit of the main body. The RF communication unit transmits a signal with high energy during a charging process. The reader supplies a charging energy and receives various state values from the main body.
