This document describes a fingerprint-based attendance record system that uses biometric fingerprint scanning and embedded systems to accurately register student attendance. The system uses a fingerprint module containing DSP, ROM and RAM to store up to 100 fingerprint templates. Students scan their fingerprints daily, which are compared to stored templates to mark attendance. If a match is found, attendance is registered, otherwise absence is logged and a buzzer alerts. The microcontroller interfaces with the fingerprint scanner and LCD to display attendance reports. It is powered by a step-down transformer supplying a regulated voltage to components like the microcontroller, LCD and fingerprint module.

1. FINGERPRINT BASED ATTENDANCE RECORD SYSTEM
(Or)
FINGER PRINT BASED ATTENDANCE SYSTEM
DESCRIPTION:
According to ancient Greek scripts BIOMETRICS means study of life.
Biometrics studies commonly include fingerprint, face, iris, voice, signature and hand
geometry recognition and verification. Many other modalities are in various stages of
development and assessment. Among these available biometric traits Finger Print proves
to be one of the best traits providing good mismatch ratio and also reliable. Registering
the attendances of students has become a hectic task as sometimes their attendance may
be registered or missed. To overcome this problem i.e. to get the attendances registered
perfectly, we are taking the help of two different technologies viz. EMBEDDED
SYSTEMS and BIOMETRICS.
Firstly discussing about Biometrics we are concentrating on Fingerprint
scanning. For this we are using FIM 3030N high voltage module as a scanner. This
module has in-built ROM, DSP and RAM. In this we can store the fingerprints of up to
100 users. This module can operate in 2 modes i.e., Master mode and User mode. We
will be using Master mode to register the fingerprints which will be stored in the ROM
present on the scanner with a unique id.
The fingerprint module will be interfaced with the microcontroller through serial
interface. The images of the students of a particular class will be scanned and stored in
the microcontroller. The students have to scan their images to register their attendance
daily. When the student has to register his attendance on that particular day, he has to
scan his fingerprint image. The fingerprint module scans the student’s image and passes

2. the scanned image to the microcontroller. The controller reads the scanned image,
compares this image with the already stored image. If both are matched, the student’s
attendance will be registered for that day. If it is not matched, the student’s attendance
will be marked as absent and buzzer indication will be given. By simply pressing a
switch, we can get the list of absentees for that day. We can see details on 16X2 LCD. (In
this project we can connect microcontroller to PC and PC maintain presents and absents
list with help of C# application-But it is optional).
