Development and application of agricultural products mobile traceability system based on NFC

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.
