Fast-moving consumer goods (FMCG) manufacturers generally adopt an agency distribution model due to their large scale and broad market. The numerous and widely distributed dealers result in complex product circulation, high management difficulty, low efficiency, and high costs. FMCG production companies in China typically use manual management methods, which cannot promptly track and monitor the flow of products, making it very easy for cross-selling incidents to occur. Cross-selling refers to the malicious marketing behavior where agents or intermediaries, driven by profit, sell the products they distribute across regions, causing market chaos and severely affecting the manufacturer's reputation. Cross-selling disrupts the original market price system and reduces the brand credibility of enterprises. For consumers, due to the market chaos caused by cross-selling, they may worry whether they have purchased counterfeit goods and develop distrust towards the company's products, which directly affects the sales volume of the product. For dealers who do not engage in cross-selling, Due to the damage caused by other dealers' cross-selling activities, many enterprises lose confidence in their products and are unwilling to continue distributing them, resulting in further losses for the companies. According to Anheuser-Busch InBev, they suffer economic losses exceeding 2 billion RMB each year due to cross-selling. Currently, the main method adopted by illegal dealers is to artificially damage the QR code identity on the product packaging, making it impossible for the production enterprises to verify the actual sales area and the cross-selling parties. If RFID technology is used to track the entire product flow, the cost is too high and not suitable for fast-moving consumer goods, which have slim profits. The aforementioned issues have long troubled many fast-moving consumer goods companies and have not been effectively resolved. This project proposes a brand-new multi-dimensional information anti-counterfeiting theory and implementation method for product packaging, aimed at designing a traceability system for fast-moving consumer goods. The system is based on digital channel coding technology, which maps the original information of goods to local areas of the three-dimensional model of the product's outer packaging through matrix encoding and decoding methods and hides it within patterns. The implanted information is associated with the information in the verification system database one by one and adopts multi-dimensional encryption and decryption techniques, ensuring that the original information can be effectively recovered even if the outer packaging is severely damaged. Combining modern information and wireless radio frequency communication technologies, the original information of goods can be remotely verified and tracked, forming an efficient and reliable anti-counterfeiting and logistics control system. In the implementation of the project, due to the complex operating environment of production lines involving a variety of mechanical and electrical equipment, low-frequency noise generated by electrical devices affects the process of information association. Therefore, we proposed a tunable bandpass filter based on magnetic media and combined it with a method for suppressing low-frequency noise applied in open fields to resist interference from low-frequency noise (see the paper and patent). It has improved the accuracy of information association. In addition, we have conducted special electromagnetic field analysis for non-uniform or lossy material properties on packaging structures (see the paper), providing a basis for the design of wireless radio frequency verification devices. The innovation points of this project are first anti-interference and anti-destruction (compared to traditional QR codes), secondly low cost (compared to RFID technology), and thirdly simplicity and ease of implementation (no need for large-scale production line transformation), effectively solving the problems of low-value-added fast-moving consumer goods manufacturing enterprises. The project's achievements began to be applied in early 2013 at the No. 4 production line of the Wuhan brewery of Anhe Brewery Co., Ltd., and by the end of 2014, it had expanded to 100 production lines in four factories including Wuhan, Tangshan, Putian, and Foshan. Through the traceability verification system, illegal dealer's cross-selling behavior was effectively curbed, and the company has recovered about 200 million yuan in direct economic losses. The company plans to apply the traceability system to all production lines across the country by the end of 2015. The project has yielded four core patented technologies and published three SCI papers in international authoritative journals (IEEE Transactions). In addition to generating significant economic benefits and promoting academic progress, the implementation of the project results has also produced notable social benefits through combating illegal dealers' counterfeiting activities, maintaining a normal price system, and market order.
