Design and Development of a Fingerprint Based Exam Hall Authentication System

Fingerprint exam hall authentication system is a system designed to allow valid users to the exam hall and block invalid users after their fingerprint scan authentication. This system offers an alternative solution to conventional paper type exam authentication. Besides, this system can also be utilized as an attendance system by storing and comparing the database of the students. Traditional paper type exam authentication and attendance list is sometimes regarded as unreliable due to paper lost or proxy attendance system. This system has been running with a R305 fingerprint scanner module and an ATmega328P microcontroller main board connected with several inputs/outputs. Barrel type push buttons are the inputs and LCD, buzzer and solenoid are the outputs used in the design. The system can be operated by push buttons or using Android app to control several operations such as fingerprint enrollment, verification and deletion. The Android app operates in similar way wirelessly by connecting to Bluetooth module but it has additional feature such as student attendance databases management and storing as well as PDF file export. The design can be operated as standalone and handheld method with both hardware and Android app is successfully implemented by using the prototype
