The construction of campus all-purpose card for secondary vocational education mainly manages teaching, personnel, finance, logistics, dormitory, attendance, access, access control and campus consumption, to fully save management resources and realize the integration and sharing of information and data. Through the common identity authentication mechanism, all parts of campus intellectualization construction are organically integrated into a whole, avoiding that each department is fighting for its own sake and settling accounts independently, resulting in multiple cards for one person, which brings great inconvenience to teachers and students. Besides, according to customer needs, local and SAAS deployment modes are adopted to solve the limitations of school-scale construction funds and personnel management. The completion of the campus card, the maturity of the two-dimensional barcodes, the application of face recognition, the gradual intellectualization of various core application technologies, and the gradual increase of cooperation between banks and schools have created mature conditions for the development of the campus all-purpose card system. Repeated investment is avoided to improve the efficiency of information construction and integrate information resources more effectively.
