Introduction With the development of global economic integration and information technology, customer personalized demand is growing day by day, and the uncertainty is also increasing greatly, which puts forward higher and higher requirements for the efficiency of supply chain in the fields of trade logistics, production and manufacturing. Due to the backwardness of item identification and identification technology, information asymmetry is caused, which seriously affects the efficiency of social logistics. In 1998, two professors of Massachusetts Institute of Technology (MIT) proposed that all goods or articles should be given a unique numbering scheme based on radio frequency identification technology (REID) for unique identification. This identification scheme uses digital coding, and realizes further inquiry of article information through the physical Internet
