RFID use of agricultural products production, processing, storage, and sale process tracking, tracing food production and processing of process, be able to effectively strengthen the management of agricultural products.
Sincere RFID barcode quality tracking system RFID tag, reading and writing by the antenna and composition, the software system including data acquisition and application system two parts, based on advanced RFID barcode equipment of all kinds of agricultural products realize from the production, processing, transportation, storage and the sales process of the whole life cycle of tracing, improve product quality and safety.
RFID tags used to identify target, it by coupling components and chip composition, can store object recognition of relevant information. Each has the only RFID tag electronic code. RFID contains the built-in antenna, can the rf antenna and reading and writing to communicate. According to the different methods of energy supply, RFID tags are divided into active and passive and active half three types. According to the store content is RFID tags can be written, RFID tags are divided into both, a written to the many times read and read only type.
In practical application, the working frequency of RFID tag is a very important parameters, the working frequency of label directly determine the RFID system is the application of the aspect characteristic. According to the working frequency of different, RFID tags can be divided into low frequency and high frequency, uhf and microwave frequency band tags. Low frequency tags mainly used in animal identification, container identification, tool identification. Vehicle entrance guard system, etc; High frequency tags are mainly applied in library management, logistics management, fixed asset management, intelligent shelves management and other areas; Uhf tags are mainly applied in supply chain management, production line automation management, container management and highway charges, etc; Microwave frequency band tag has also started to application.
