Food Traceability System Based On Android
Abstract: In recent years, the global food security incidents continue to occur. There are many food safety problems in China. At the same time, the establishment of China's food traceability system is not perfect. Consumers need a safe food traceability system to protect food safety. This paper designs a food traceability system based on Android, through the ZXing class library import, to achieve the two-dimensional code information scanning recognition; through the map SDK import, to achieve the positioning display function; the use of database technology to complete the product information query , Food traceability tracking, enterprise information query and other functional modules. The final completion of the system will enable consumer users to have sufficient confidence in food safety to meet the business users to trace the food tracking and government departments of food production supervision and management, while better protection of food safety.
