Beijing twelve-centimeter science and technology co. Ltd. (hereinafter referred to as “12cm”) is a chinese subsidiary of korea's 12cm company, which has the technology of e-mail stamps and the source technology of over 200 patents. The easis seal is a smart o2o seal for global commerce. Many well-known global and chinese chains are now applying this technology. When the customer closes the account at the counter, the applet is opened and the purchase amount is entered at the appropriate interface, and once confirmed by the cashier, the score can be stamped on the phone with a smart stamp. The whole process takes five seconds! The easy operation has simplified the process of entering the customer's score and solved the pain of the mall's inability to achieve real-time and unified points. Smart stamp scores are unique compared to other solutions, such as manual entry in the service desk, sweep points, etc. This is also an important basis on which both parties can achieve strategic cooperation. As a country-wide business digital operator, wisdom has been tasked with “making real business more intelligent and consumption better”, providing complete smart business solutions for large entity businesses such as shopping centres, department stores, airports and mitigation systems throughout the country. It has successfully contributed to the digital transformation and performance growth of well-known shopping centres, such as monopolitan, central, and amalgam. With the advent of the mobile internet, twitter has become a standard application for almost every user with a smartphone, and the micro-trust applet has become an important vehicle for commercial branding, customer touch and activity. The integration of nearby small programs, sweeps, card packs, micro-mail payments, social sharing, etc., has resulted in a “micro-intellectual retail model” of assembly identification, self-help purchase, data deposition, marketing, service alerts, etc. Since the start of the micro-program, the smart map has deepened the marketing potential of the "package + new retail", integrated marketing online and offline, multi-scene connectivity to users and the development of community fission, welfare maps, smart parking, face-to-area splits, etc. This time, after becoming an agent for the 12cm-enabled china district shopping centre/expendable, the wisdom chart will organize an operational team, based on the application of the smart seal, to introduce more business games to help real business to switch to new retail。
