It is understood that the "smart label" attached to the outer packaging of goods reflects the external temperature and storage time of the product in real time and directly through the color change from green to red, so as to know whether the product is fresh or deteriorated in logistics and sales. The "smart tag" technology is invented by the State key Laboratory of rare Earth Materials Chemistry and applications of Peking University and the Chinese University of Hong Kong, and is authorized by the national invention patent. It has the advantages of low cost, wide application, safety and non-destructive monitoring of product quality.

Li Wei, executive vice president of Lanthanum Color Technology Co., Ltd., a shareholding enterprise of Peking University, believes that the market-oriented application of "smart tags" will provide good and reliable service and guarantee for producers, logistics, sellers and consumers throughout the process. to protect the quality of products.
