Summary:According to a visible light coding mode capable of being identified by an RFID tag, the RFID tag is a photosensitive tag, a switch with the frequency of at least 80 Hz is used for controlling visible light to flicker and irradiate the RFID tag and an antenna of the RFID tag, and therefore flicker information codes of the visible light are added to an EPC of the RFID tag. During decoding, visible light coding information can be obtained by analyzing the phase change of the EPC signal in the communication process. In this way, the flicker information code of the visible light is added to the EPC of the RFID tag, and the coded data of the visible light can be obtained by analyzing the phase change of the EPC signal in the communication process during decoding. 一种可被RFID标签识别的可见光编码方式，所述RFID标签为光敏标签，以频率为至少80Hz的开关控制可见光闪烁照射RFID标签及其天线，从而将可见光的闪烁信息编码附加在RFID标签的EPC之上，解码时通过分析通信过程中EPC信号的相位变化即可获得可见光编码信息。通过该方式将可见光的闪烁信息编码附加在RFID标签的EPC之上，解码时通过分析通信过程中EPC信号的相位变化即可获得可见光的编码数据。
