The Construction of the Agricultural Products Traceablity Code System Based on a Type of Barcode Technology

Using Visual Basic as the development platform, the agricultural products traceability code system was constructed based on the PDF417 two-dimensional bar code technology through the embedded c++ dynamic link library (DLL) in the paper. The system implemented the expression of the related information for agricultural products origin, agricultural products, certification types, agricultural products processing enterprises, production date, shelf life of agricultural products and so on. Through the effective traceability of agricultural products, the requirements of the consumers to agricultural product quality were satisfied by the system.
