A Presentation on
"Fingerprint Based Exam Hall Authentication"
OBJECTIVES
● To createa system that is capable of tracking impersonators in
the examination system using the methodology of finger print
biometrics.
● To reduce rate of corruption in the educational sector and
increase the rate of self-confidence on students.
● enforce strict security measures that ensure unregistered
students do not write exams for other registered students.

INTRODUCTION
● Authentication hasalways been a major challenge in all types of
examination.
● Verification of the authentic candidate is not an easy task, and also it
consumes a lot of time and process.
● This led to the design of Fingerprint based exam hall authentication
system that is designed to pass only users
verified by their fingerprint scan and block non verified users.
COMPONENTS
● Center TapTransformer
● Rectifier
● Arduino uno Microcontroller
● R305 Fingerprint Sensor
● Resistor
● LCD (liquid crystal display)
● Capacitors
● Transistors
● Cables and Connectors
● Diodes
● PCB
● LED (light emitting diode)
● Switch
● IC MAX232

● IC MAX232:
1)It is an integrated circuit which converts the signals
from the RS232 serial port to the proper signal.
2) The MAX232 can convert the signals like RX, TX,
CTS, and RTS and it is a dual driver/receiver.
8.
● Center TapTransformer:
1) A Centre tapped transformer works in more or less
the same way as a usual transformer.
2) the difference lies in just a fact that its secondary
winding is divided into two parts, so two individual
voltage can be acquired across two line ends.
● Rectifier:
1) center tap rectifier converts AC into DC .
2) It uses two diodes that are connected to secondary of
Transformer.
● Voltage Regulator:
● R305 FingerprintSensor:
1) R305 Fingerprint Module is a serial fingerprint scanner
which can be directly connected to the PC's com port.
2) R305 Fingerprint Sensor can easily be connected to
any controller via MAX232 IC.
3) A Fingerprint Scanner performance a very basic
function: It takes an image of your fingerprints and
compares it against the data of previously sacnned
fingerprint .
11.
● LCD (LiquidCrystal Display):
1) LCD is combination of two states of matter, the solid and the liquid.
2) LCD uses a liquid crystal to produce a visible image.
3) Liquid crystal displays are super-thin technology display screen that
are generally used in laptop computer screen, TVs, cell phones and
portable video games.
