摘要: A method of wireless communication, with a circuit that includes radio frequency identification (RFID) reader, can be carried out using is configured and arranged to communicate RFID cards use load modulation an RF carrier provided by the reader. presence (RF) detected on antenna. local clock signal generated. difference between detected. In response difference, modified reduce difference. Load mimicked modulating encode data; driving antenna modulated signal.
