A Novel Attendance System Via Integrated Wifi And Blockchain Technologies

Student Attendance is part of the academic curriculum, student needs to attend classes for lectures which is part of the major reason for coming to school for study. Keeping the attendance record safely, transparent, immutable and easily accessible is very essential. This study aims at designing a Wi-Fi attendance system that can allow a student to mark attendance with their phone or laptop, the record will be saved on distributed and decentralized blockchain. This attendance system is implemented in such a way that students will mark their attendance by inputting their unique student number on a webpage after they have initiated a connection with the Wi-Fi microcontroller module installed in the classroom, This record is been logged and arranged on a server database with time in and time out, the student name, student number, date, course ID and it can be generated for every registered student. The generated attendance can be uploaded to a node in a blockchain via the internet. The generated attendance record can easily be accessed with data reliability, and transparency with the aid of peer-to-peer features of distributed ledger to be available to other parties such as a parent, student or anyone on the network.
