Abstract: ObjectiveThe system was designed to complete the automatic acquisition and processing of agricultural products processing and packaging,transport,storage,sales and other procedures,and overcome the common shortco-mings such as specialized reading equipments were needed when using radio frequency identification(RFID)and two-di-mensional code in agricultural products traceability system.With these efforts,the quality and safety of agricultural pro-ducts could be guaranteed and the agricultural products traceability from farm to dining table was realized.MethodSys-tem client was designed and developed based on cellphone Android system.Android application programming interface (API)was used to read or write near field communication(NFC)tag,Android-async-http was applied as network request frame,universal-image-loader as picture display framework,Gson as Json data serialization and anti-serialization frame-work. Location base service(LBS)was used for logistics positioning and track following.The system server was deve-loped based on Java Web in which JFinal was used as development framework.ResultThe agricultural products mobile traceability system based on NFC included user management,traceability code reading and writing,package code bin-ding,vehicle information input,automatic collection of storage information,logistics path tracking,traceability informa-tion query and other functions.It allowed agricultural enterprises and warehouse personnel to input traceability informa-tion efficiently in agricultural products processing,packaging,transport,storage and sales. Consumers could also use cellphone with NFC functions to inquire agricultural information.ConclusionThe mobile agricultural products traceabili-ty system based on NFC can fully meet the requirements of agricultural enterprises and the public to trace back agricultural products information.
