Abstract
A radio frequency identification (RFID) communication system and method is provided to resolve the power-consuming problems of an active RFID tag while operating at a receiving mode in a long duration. A designated channel is established between the reader and the RFID tag, and also the reader sends a designated message so that the actuated active RFID tag can receive the designated messages and dynamically enter into a receiving mode. Therefore, normal communications may be conducted between the reader and the RFID and the usage period or technical performance can be improved as well.
