基于RFID、QR Code、NFC建立肉食品供应链追溯系统

为了加强肉食品供应链的监管,达到正向可追踪,逆向可追溯的目的.把供应链划分为饲养、加工和流通三个阶段,根据每个阶段的工作特点,选择了RFID、QR Code、NFC等技术的组合应用开发了追溯系统.该系统实现了分段管理:(1)在饲养阶段应用自制的"复合型RFID耳标"兼顾了远距离识别和大容量生产日志的存储;(2)在加工阶段应用成本低、抗污损能力好的QR Code码实现了肉块分割和识别追踪;(3)在流通阶段应用了NFC技术实现管理,方便消费者利用手机扫描成品包装上的NFC标签,实现供应链的逆向追溯,积极参与产品的质量监管.该系统的应用能够对肉类供应链实现全程、无缝的监管,同时保障了消费者知情权,增强消费信心.

Establishment of traceability system for meat food supply chain based on integration of RFID,QR Code and NFC

To strengthen the supervision of meat product supply chain so that both forward and reverse traceability can be realized, combination of radio frequency identification ( RFID) , quick response ( QR) code, and near field communication ( NFC) were used to develop a traceability system. Segmented management mode, which included 3 stages of the supply chain, namely feeding, pro-cessing and circulation, was applied in the system. To be specific, in the feeding stage,“multi-functional RFID ear mark” realized both long-range identification and storage of high-volume data log on raising and transporting livestock. In the subsequent processing stage, low-cost and stain-resistance QR code was able to trace the part of livestock which the meat came from. Finally, in the circu-lation stage, NFC technology enabled consumers to find the history of the meat by scanning NFC tag on the package of meat via mo-bile phone. To summarize, this traceability system can realize a whole-course supervision of meat product supply chain seamlessly so that consumers will feel more comfortable and confident on what they eat daily.
