Construction of Traceability System by Using Simple and Handy Type RFID Reader

This chapter picks up and explains some problems on system costs or specifications faced when trying to construct a traceability system by using RFID tags. The peripherals including RFID reader are even now expensive because it is not widespread in the market. Because of the sense of comparatively high price of the system cost and the dilemma to the specification, the impression that construction approach of the traceability system using RFID tags may be in the contemplation period is strong. This chapter shows these problems obtained from a market trend concerning the traceability in recent years and the result of reviews of the RFID tag applications or proof experiments. Next, the points of the future traceability system construction using these new technologies, especially about simple and handy type RFID reader using FPGA are described.
