| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 94 === Radio Frequency Identification (RFID) systems have become one of the most popular technologies recently. It can replace the traditional role of bar code system in the supply or service chain by reducing the needs of manpower.
In this thesis, we first carry out a tag module by Verilog HDL that complied with Auto-ID Center Class-1 Standard. Then, a fully tag search algorithm is designed to work in a simple RFID reader to find out all the tags coexisting in the field of the RFID reader. This search algorithm queries the tags for identification information efficiently. It can identify up to six hundred tags in eight seconds. Finally, we propose two modifications about the original architecture and focus our attention on how to further reduce the use of logic gate to efficiently improve search performance. According to our experimental results, the modified architecture achieves 200% improvement over the original standard.
