Simply put, the campus card system means that all teachers, students and employees in the school hold a campus card, which replaces all previous documents (including student ID card, work permit, library card, medical card, pass, etc.). ). All or part of the functions of teachers and students can go in and out of school, do things, do activities and spend money with this campus card, and realize self-service with the bank card, and finally realize "one card in hand, travel all over the campus". This management mode replaces the traditional consumption management mode and brings high efficiency, convenience and safety to school management. All-in-one card system is an important part of digital campus construction, and it is one of the basic projects to provide information collection for campus informatization, and it has some functions of school management decision support system.

Campus card is an important part of "digital campus", which should mainly have the functions of comprehensive consumption, identity recognition, financial services and public information services. The whole system should be well connected with the banking system, the original school system and the school management information system, and appropriate interfaces should be reserved for the school's potential management information system to provide necessary help for the school to add other management system interfaces at any time after the project is completed.
