Application of RFID technology in tea anti-counterfeiting
Tea is an indispensable drink in life, and the habit of drinking tea has become the norm in life. The quality of tea has always been the concern of many tea drinkers. In recent years, the frequent occurrence of tea quality and safety crises has aroused widespread concern among consumers. To ensure the quality and safety of tea products, the products must be traceable. "Tea product safety traceability system" uses automatic data collection technology to uniquely identify and link the management objects of the supply chain links such as the growth, processing, storage and retail of tea raw materials. Once the tea has a safety problem, it can be traced through these signs to accurately narrow the scope of the tea safety problem, find out the link where the problem occurred, and even trace back to the source of tea production.
Application of RFID system in all aspects of tea products
Production stage: The producer stores the product name, variety, place of production, batch, pesticide application, producer information and other necessary content in the RFID tag, and uses the RFID tag to record the initial product information and production process. At the time of purchase, the label information is used to quickly sort the products, and different purchase prices are given according to the different conditions of the products.
Processing stage: Use the information in the RFID tag to sort products, and only those products that meet the processing conditions can be allowed to enter the next processing link. For products that enter the processing link, use the information recorded in the RFID tag to target different products. Processing to ensure product quality. After processing, the processor adds the processor’s information, processing method, processing date, product grade, shelf life, storage conditions, etc. to the RFID tag. In the transportation and storage stage: use RFID tags to understand and track the transportation route and time of transportation vehicles with fixed readers installed along the way, install fixed readers at warehouse imports and exports, and automatically record the entry and exit of products. Many agricultural products have high requirements for storage conditions and storage time. Use the information recorded in the RFID tag to quickly determine whether the product is suitable for storage in a certain warehouse and how long it can be stored; when leaving the warehouse, select priority according to the storage time The products in the warehouse can avoid economic losses; at the same time, the use of RFID can also realize the rapid inventory of the warehouse, helping the management personnel to know the status of the products in the warehouse at any time.
In the sales phase: Merchants use RFID tags to understand the status of purchased goods and help merchants implement access management. When collecting money, using RFID tags can confirm the price of a customer's purchase of goods more quickly than using a barcode, and reduce the waiting time for customers. Merchants can write the name of the product, sales time, salesperson and other information into the RFID tag to confirm the product when the customer returns and recalls the product. When there is a problem with the product, because the information of the product's production, processing, transportation, storage, sales and other links is stored in the RFID tag, the entire process can be traced based on the content of the RFID tag.
