Project Features:
• College attendance system with finger print module
• Exam hall paper sets generation with finger print
• Detection of Digital cheating in exam hall like Mobile SMS/ CALLs
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.
 The most common electronic equipment used is cell phones. With advancement in
communication technology, the requirement of cell phones has increased
manifold. A cell phone typically transmits and receives signals in the frequency
range of 0.9 to 3GHz. This article provides a simple circuit to detect the presence
of an activated cell phone by detecting these signals.
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
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

2. 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).
