Problems solved by technology

[0003] At present, the logistics industry as a whole lacks coordination, logistics information sharing and opening are not enough, the phenomenon of "information islands" is prominent, and the logistics and warehousing industry is still scattered and weak in terms of services

At the same time, there is a lack of effective connection and intercommunication among logistics enterprises, between different regions, between different warehouses, and between different modes of transportation, and the national logistics has not yet formed a unified system

The data storage in each link of the product from the factory, transportation and storage is opaque, the data lacks security and is difficult to share, resulting in incomplete product traceability and difficulty
