In the last few years, to reduce the cost and raise the efficiency of the logistics management, the related researches of the radio frequency identification (RFID) have been investigated by several business corporations such as Wal-Mart, Gillette, Kraft Foods, P&G, HP, Microsoft, IBM, Sun Microsystems, and SAP, etc. This gives us a motivation to develop a RFID data system by using the techniques of RFID, Wireless Fidelity, Embedded System, and Web based Database System. The advantages of the proposed ARM Based RFID Data System are: (1) it can reduce the routing complexity of the network, and (2) the system functionality is flexible.
