Abstract: -This paper presents a proposed Fast search Algorithm based Anti-collision technique for Radio Frequency Identification passive tags. The Anti- collision technique architecture consists of two main subsystems; First subsystem and Second subsystem. The First subsystem is to detect any error in the incoming messages. Then the identification bit of the no error packet will be fed to the next subsystem. The Second subsystem is to identify the tag by using the proposed Fast-search Lookup Table. The proposed system is designed using Verilog HDL. The system is simulated using Modelsim and synthesized using Xilinx Synthesis Technology. Finally the Anti-collision technique architecture is resynthesized using from the hardware verification results, it shows that the proposed Anti-collision technique system enables to identify the tags without error at the maximum operating frequency of 261 MHz and the average connection delay is 1.15 ns. Maximum pin delay is 4.177ns.
