Abstract: Aiming at the problem that Radio Frequency Identification(RFID) tag has short storage space and higher data repeatability, this paper presents an improved RFID tag data compression algorithm based on the LZW. The algorithm uses multi-tree storage structure to enhance data compression speed and improves the operating method for threshold determination to avoid the waste of storage space. Experimental results show that compared with other algorithms, this algorithm has higher performance in compression time and efficiency.
