Abstract:

GS1 is a new name of EAN/UCC, which is composed of encoding system, automatic identifiable data carriers and electronic data exchange standards. Due to unsolved problems related to the origin tracing of foods, standardization of RFID tags and sharing of dynamic data, it is urgent to establish a full supply chain traceability system for beef. In this study, a general framework of GS1 full supply chain traceability system for beef was established using RFID tags and EAN/UCC codes with EPCglobal tag data standards to conduct tracking from farm to fork. Each information server contained access layer, business layer and resource layer. These servers were heterogeneously distributed to provide user an accessing interface through SOAP or HTTP protocol. In order to accomplish the sharing of dynamic data, information-searching service combined with target-name service was used to locate dynamically distributed information servers.
