The design of RFID electronic tags based on laser holographic technology is designed to improve the ability of reading and writing of RFID tags. The traditional electronic label design uses the coupling element to realize the space coupling and the transmission of the electronic tag RF signal, when the high intensity electromagnetic interference, the radio frequency recognition performance is not good. A design method of electronic label based on laser holographic scanning and radio frequency identification is proposed, and the design of multi frequency and multi format RFID tag is proposed. First the overall design of the RFID electronic tags, electronic label system overall design and function of the technical indicators analysis, hardware circuit design and software development of the electronic label and the hardware module of the electronic label mainly includes the information processing module, can communication module, data encryption module, radio frequency identification module, antenna module and man-machine interface module etc. , system design using ST ultra low power arm cortex ＂ -M0 as the main control chip, design software to establish in Linux2. 6. 32 kernel of the platform. Experiment results show that, using the laser holographic RFID electronic tag has the lower power consumption, smaller range of oscillation attenuation characteristics weakened, improve the RFID performance and work reliability, radio frequency identification of input and output performance better, showing the superior performance.
