HTML5 is an advanced web technology that allows for cross-platform capability, eliminating the need for users to download apps. It enhances information dissemination and eliminates information barriers, while also being low in development costs and requiring less code. However, the link established between HTML5 pages and users is short, and user identification is a unique code randomly assigned by the site, which is stored in the browser's cache. Sometimes, event planners use QR codes to link H5 mini-programs, which attendees are more willing to register for events and learn about information through scanning codes. However, these convenient H5 pages cannot help identify customers personally, making it difficult to design activities that interest existing customers more.
