Research on Traceability System of Food Safety Based on PDF417 Two-Dimensional Bar Code

摘要：

In this paper, through the research on twodimensional bar codes of food source tracking; a set of traceability tracking system was designed based on the two bar coding algorithm and decoding algorithms. This system could generate PDF417 code based on food production, logistics and transport, su-permarket and other storage information. Consumers could identify PDF417 code through a client based on B/S architecture so that a simple process of food traceability has been completed.
