RFID (Radio Frequency Identification), a technology existing for years, has potential uses in a variety of applications. Though not without issues and challenges, RFID is a promising technology which analysts expect to become ubiquitous in the coming years, helping organizations solve problems in supply chain management, security, personal identification, and asset tracking. The purpose of this paper is to applying RFID technology in production control in a discrete manufacturing system, which needs control the production process in real time in order to improve the management level of production efficiency and quality. In particular, we build a RAMS (RFID Activity Monitor System), for sanitary ware manufacturing, which is connected to the existing ERP System by database so as to satisfy real time control requirement.
