A student ID is a unique identification number or card assigned to each student at an educational institution. It helps schools keep track of students' records, attendance, and grades. The ID often includes the student's name, photo, and other relevant information. Student IDs are commonly used for various purposes, such as accessing library services, entering campus facilities, and participating in school events. They may also be required for online learning platforms and exams, ensuring that only authorized students can access specific resources and services.
