This thesis investigates the feasibility and advantages of establishing a more efficient distribution system utilizing new technologies such as the internet and radio frequency identification (RFID). Introducing and promoting the diffusion of commodity traceability (the ability to trace the distribution route of products and materials) is necessary in order to make distribution and logistics more efficient, to clarify the safety of foods and daily necessities, to prevent theft and to monitor the dealing of stolen or imitation goods. This thesis focuses especially on a commodity (products) traceability system to enhance transparency for consumers. The expected effects of RFID can be summarized as follows. - Substantial improvement in logistics efficiency. - Higher consumer safety, quality management, and security for foods, drugs, and goods (clothes, books, electric appliances, automobiles, etc.) through improved traceability.
