Smart Mall "is an embedding of digital and intelligent technologies such as the Internet of Things, cloud computing, mobile commerce, and e-commerce into traditional shopping malls. Through smart commercial displays, information exchange between people and things is more convenient. As one of the main intermediaries, smart screens will bring changes to everyone's way of life and procurement. High definition smart screens make shopping mall information display within reach. We transition from product brands to scene brands; segmented small scene solutions under large scenes, linking ecological circles and supply chains, forming a win-win closed loop for all stakeholders. We will combine the dual+branding strategy (product+service, scene+ecology), starting from smart screens, for exhibition halls. Provide a complete set of exclusive commercial display solutions and services for N scenes in the exhibition hall.
