Chicken and egg food traceability system based on NFC and QR code technology was designed. The traceability system registers and uploads the information of raised chickens through the chicken foot ring embedded with NFC tag. The system generates egg QR code according to the registered information and prints it on the eggs corresponding to the raised chickens. It is used for consumer users to scan and query the relevant information of the eggs and the raised chickens, including the breeding address, breeder and breeding record of the raised chickens. The system is designed based on the classic three-layer mode of the Internet of things and the B / S architecture. The system mainly realizes the traceability of chickens through NFC tags and eggs through QR codes. It has high stability and great application and promotion value.
