RFID stands for Radio Frequency Identification, a technology that uses electromagnetic fields to identify and track objects. RFID tags are small devices that can be attached to objects, such as student ID cards, and store information about them. RFID readers are devices that can scan the tags and access the information stored on them. RFID based school attendance system is a system that uses RFID tags and readers to record and monitor the attendance of students in schools.
In a RFID based school attendance system, each student is given an ID card with an RFID tag embedded in it. The ID card contains the student's name, class, roll number, and other relevant information. The RFID tag has a unique identification number that is linked to the student's information in a central database. The school premises are equipped with RFID readers at various locations, such as the entrance, the classrooms, the library, and the cafeteria. The RFID readers are connected to a computer network that communicates with the central database. When a student enters or exits the school premises, or attends a class or an activity, they have to tap their ID card on the RFID reader. The reader scans the tag and sends the identification number and the time stamp to the database. The database records the attendance of the student and updates the information accordingly. The database can also generate reports and alerts based on the attendance data, such as daily, weekly, or monthly attendance summaries, absent or late students, or students who skip classes or activities. The reports and alerts can be accessed by authorized people, such as teachers, parents, or school administrators, through a web portal or a mobile app.
