The main reason is the change of the management mode of student status and the progress of technology. In the past, students' school information was usually recorded in paper form in their school status or student files. With the development of electronization and informatization, many colleges and universities gradually adopt electronic student status management system to store students' personal and academic information in electronic databases. This can improve the efficiency of information management, reduce the physical storage space of files, and facilitate the real-time update and query of students' status. In addition, student identity authentication is usually achieved through a student ID card, which will be printed with the basic information of the student and the logo of the school. Student ID cards can generally be used to prove students' identity and enjoy related rights and interests, such as borrowing library and purchasing student tickets.
