Fingerprint attendance system is a hand-held device which aims to automate entire attendance procedure of classroom using biometric technology. The device can be carried to the classroom and can be passed to the students. The hand-held device can take attendance without the intervention of teacher. This device would operate from a rechargeable Li-ion battery. The GUI application would help the teacher to manage the device through a host PC.
