According to Lei Feng.com, on July 14, 2019, the 4th Global Artificial Intelligence and Robotics Summit (CCF-GAIR 2019) was officially held in Shenzhen. Wang Junjie, dean of the Suning Retail Technology Research Institute, said that Suning’s smart store solution covers all aspects of the entire business. In the process of customers visiting the store, the user experience is enhanced by cloud shelf and blockchain traceability. For example, if a consumer buys fruit, he can pick up the fruit and know where it is produced. How long it took to transport it from the place of origin to the store, and what characteristics and attributes it has, all clear.
