Design of 433MHz low power anti-collision RFID system

A design method of low power anti-collision RFID system is presented in this paper. The system power consumption is effectively reduced by circuit design and work mode selecting. An improved anti-collision algorithm is used in the system, reducing both the tag collision probability and the power consumption. The design method has been used in a 433MHz RFID system, enhancing the identification efficiency and reducing the system power consumption successfully.
