Anti-counterfeiting and traceability of RFID in retail industry

　　The principle of anti-counterfeiting is to write the product identification number (ID), which is the anti-counterfeiting code, in the RFID chip. This ID is unique in all links such as production and sales; the chip is made into a label, and the electronic label is attached to the product to make it Become an integral part of the commodity. When the electronic tag is forced to separate from the product, the integrity of the product is destroyed, the product is deemed to have been consumed, and the anti-counterfeiting ends.

　　Food safety incidents such as tainted milk powder, skinny essence, cooking oil, and dyed steamed buns have caused a lot of noise, and RFID food traceability is the most effective technical means to ensure food safety. Using RFID as an information carrier, and relying on technologies such as network communication, system integration, and database application, a set of information platform established by government supervision, sales and other links. Build a full traceability system to achieve records of every link in the entire industrial chain from production, processing, storage, and transportation to terminal consumption.

　　advantage:

　　1. No mechanical wear, anti-wear;

　　2. The physical interface of the reader ensures its own security;

　　3. Improved label password protection;

　　4. There is a mutual authentication process between the reader and the tag.

　　Application of RFID in supply chain management

　　Each supplier has an electronic label, which can be used for settlement, reconciliation, query and other applications based on this label (with uniqueness); in inventory management, the system can automatically identify the inventory of the required goods according to the electronic label on each package Information such as area, inventory quantity, storage quantity and time; in terms of member management, members can be identified quickly and effectively to better provide targeted services to customers entering the store; in cash register management, the cash register system can be unmanned In the case of intervention, the electronic label on the product is automatically recognized, the total price of the product is automatically calculated, and the bill is automatically printed out when the customer arrives at the cashier area; in terms of product safety management, the monitoring device automatically monitors the unauthorized electronic label in the area In case of abnormal movement, the sound and light alarm device can be activated.

　　Advantages: high degree of work automation, fast processing speed, without too much human intervention in the processing process.

　　Disadvantages: The cost of electronic tags is expensive. When the cost of electronic tags cannot be reduced, the application prospect of RFID in the small and medium retail industry is not optimistic. However, because of its obvious advantages, it will be a development direction in the future.
