The mini-app is an intelligent, flat-to-one platform that can participate in a business-free business by scanning 2-dimensional code through micro-credit payments, and a new type of promotional platform. The role of small and microteams in returning to the platform is divided into five roles: consumer, commercial, district, municipal and provincial. The vendor completes the information on the platform, and the platform's review will become a business. On the small micro-team return platform, nearby stores can be seen to support navigation for consumption. When consumers go to the store for consumption, the merchants go to the pool, which amounts to the amount of consumer consumption, the system goes back to the consumer, and the merchants can negotiate with the platform**. The queuing back-to-do model is now well received by young people, in the form of consumer incentives that allow consumers to double consumption, proactively share, maintain attention and increase commercial sales. There are now many line-back platforms with similar business models. The small micro-team system, which affects people's mobility, is now being further developed to provide access to users. The mini-micro-app is affiliated with henan tenaor technology ltd., which has many years of experience in the development of internet-based software, provides customized development services for various distribution models, such as the roll-back system, the secondary distribution system, the repurchase distribution system, the role-backer system, the distribution red system, etc。
