This document describes a fingerprint-based ATM system that uses fingerprint scanning as authentication for transactions. The system stores users' fingerprint data in an Aadhaar database. During transactions, the user's fingerprint is scanned and matched against the stored data. If a match is found, the transaction is completed. Otherwise, the transaction is cancelled for security. The document outlines the proposed system design, including modules for fingerprint scanning, iris detection, database storage, and transaction authorization based on biometric authentication. It concludes that the fingerprint-based system allows for secure and easy-to-use ATM transactions.

FINGERPRINT BASED
ATM SYSTEM

3. ABSTRACT
• The main purpose of our system is to make online transaction more secure and user-
friendly. Here we are using Fingerprint scanning biometric and iris scanning to provide access
to ATM machine. Data of a fingerprint and iris is stored in Aadhar database. Bank provide
authentication to the customer that can be access while performing transaction process. If the
fingerprint and iris match is found in data base then transaction take place. After verification,
if fingerprint and iris does not match transaction will be cancelled. Using fingerprint based
ATM system user can make secure transaction. Biometric can be used to identify physical and
behavioral characteristics of user fingerprints. There are many biometric devices like iris
detection, face recognition, fingerprint. In our Project, we are using fingerprint biometrics and
iris detection. Users fingerprint are scanned using biometric, eye ball are scanned through
camera and stored in database. All fingerprints have unique characteristics and patterns.
Fingerprint biometrics and camera are easy to use, cheap and most suitable for everyone.
Characteristics of fingerprint and iris vary from person to person. Fingerprint and iris is a
unique identity of user.

5. • INTRODUCTION
• Fingerprint Based ATM is a desktop application where fingerprint of the user
is used as a authentication. The finger print minutiae features are different for each
human being so the user can be identified uniquely. Instead of using ATM card
Fingerprint based ATM is safer and secure. There is no worry of losing ATM card
and no need to carry ATM card in your wallet. You just have to use your fingerprint
in order to do any banking transaction. The user has to login using his fingerprint
and he has to enter the pin code in order to do further transaction. The user can
withdraw money from his account. User can transfer money to various accounts by
mentioning account number. In order to withdraw money user has to enter the
amount he want to withdraw .The user must have appropriate balance in his ATM
account to do transaction. User can view the balance available in his respective
account.

6. • PROPOSED SYSTEM
• Design Approach This project was developed using functional design approach. It is a modular
approach. Each module is a function of its own and as the modules are independent, the change in
functional implementation of module will affect the functional implementation of the other modules
minimally. Each authentication step in the proposed solution is identified into three independent
modules for implementation purposes and integrated. The first module implements a scrambling
keypad, second a color-coded password combination and finally a biometric fingerprint
authentication. Each functional module consists of its own implementation and sub modules. 2.2
Detailed Design This project consists of three steps of authentication: The 6-digits ATM PIN number
on a scrambling keypad, color-coded combination password identification and fingerprint
recognition. A user must first register with all three before accessing his records. The user records
are stored in a SQLite database in the form of rows. When a user authenticates using his account
details, they are matched against the records in the database and the result (“valid” or “invalid” user)
is returned. The registration and authentication processes are further explained with respective
activity, sequence and architecture diagrams. 7 2.2.1 Registration The activity diagram below shows
the workflow of activities for user registration process. In real world, a user swipes his debit/credit
card to authenticate and use a teller machine. The bank issues these cards to users with bank
accounts, so the user details are already registered with the bank. For demonstration purposes, this
project stores user details entered by the user and the user needs to enter his account number to
authenticate with the three steps

7. • POWER SUPPLY
A power supply is an electronic device that supplies electric energy to an electrical
load. The primary function of a power supply is to convert one form of electrical
energy to another and, as a result, power supplies are sometimes referred to
as electric power converters. Some power supplies are discrete, stand-alone devices,
whereas others are built into larger devices along with their loads. Examples of the
latter include power supplies found in desktop computers and consumer
electronics devices.

8. • TRANSFORMER
A transformer is a static electrical device that transfers electrical energy between two or more circuits. A
varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a
varying electromotive force across a second coil wound around the same core. Electrical energy can be
transferred between the two coils, without a metallic connection between the two circuits. Faraday's law of
induction discovered in 1831 described the induced voltage effect in any coil due to changing magnetic flux
encircled by the coil. Transformers are used for increasing or decreasing the alternating voltages in electric
power applications, and for coupling the stages of signal processing circuits. Since the invention of the first
constant-potential transformer in 1885, transformers have become essential for the transmission,
distribution, and utilization of alternating current electric power. A wide range of transformer designs is
encountered in electronic and electric power applications. Transformers range in size from RF transformers
less than a cubic centimeter in volume, to units weighing hundreds of tons used to interconnect the power
grid.

12. • LCD
A liquid-crystal display (LCD) is a flat panel display, electronic visual display, or
video display that uses the light modulating properties of liquid crystals. Liquid
crystals do not emit light directly.
LCDs are available to display arbitrary images (as in a general-purpose computer
display) or fixed images which can be displayed or hidden, such as preset words,
digits, and 7-segment displays as in a digital clock. They use the same basic
technology, except that arbitrary images are made up of a large number of small
pixels, while other displays have larger elements.

13. • LED
A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn-
junction diode, which emits light when activated.]When a suitable voltage is
applied to the leads, electrons are able to recombine with electron holes within the
device, releasing energy in the form of photons. This effect is called
electroluminescence, and the color of the light is determined by the energy band
gap of the semiconductor.

14. FINGERPRINT
Fingers canning, also called fingerprint scanning, is the process of electronically
obtaining and storing human fingerprints. The digital image obtained by such scanning
is called a finger image. In some texts, the terms fingerprinting and fingerprint are used,
but technically, these terms refer to traditional ink-and-paper processes and images.
Finger scanning is a biometric process, because it involves the automated capture,
analysis, and comparison of a specific characteristic of the human body. There are
several different ways in which an instrument can bring out the details in the pattern of
raised areas (called ridges) and branches (called bifurcations) in a human finger image.
The most common methods are optical, thermal, and tactile. They work using visible
light analysis, heat-emission analysis, and pressure analysis, respectively.

15. • GSM MODULE
• A GSM modem is a specialized type of modem which accepts a SIM card, and
operates over a subscription to a mobile operator, just like a mobile phone. From
the mobile operator perspective, a GSM modem looks just like a mobile
phone. When a GSM modem is connected to a computer, this allows the computer
to use the GSM modem to communicate over the mobile network. While these
GSM modems are most frequently used to provide mobile internet connectivity,
many of them can also be used for sending and receiving SMS and MMS messages.

16. • RELAY
• A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate
a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is
necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled
by one signal. The first relays were used in long distance telegraph circuits as amplifiers: they repeated the
signal coming in from one circuit and re-transmitted it on another circuit. Relays were used extensively in
telephone exchanges and early computers to perform logical operations. A small cradle relay often used in
electronics. The "cradle" term refers to the shape of the relay's armature. When an electric current is passed
through the coil it generates a magnetic field that activates the armature and the consequent movement of
the movable contact either makes or breaks (depending upon construction) a connection with a fixed
contact. If the set of contacts was closed when the relay was de-energized, then the movement opens the
contacts and breaks the connection, and vice versa if the contacts were open. When the current to the coil is
switched off, the armature is returned by a force, approximately half as strong as the magnetic force, to its
relaxed position. Usually this force is provided by a spring, but gravity is also used commonly in industrial
motor starters. Most relays are manufactured to operate quickly. In a low-voltage application this reduces
noise; in a high voltage or current application it reduces arcing.

17. • DC MOTOR
• A DC motor is any of a class of rotary electrical machines that converts direct
current electrical energy into mechanical energy. The most common types rely on
the forces produced by magnetic fields. Nearly all types of DC motors have some
internal mechanism, either electromechanical or electronic; to periodically change
the direction of current flow in part of the motor.

18. • KEYPAD
• A keypad is a set of buttons arranged in a block or "pad" which usually bear
digits, symbols and usually a complete set of alphabetical letters. If it mostly
contains numbers then it can also be called a numeric keypad. Keypads are found
on many alphanumeric keyboards and on other devices such as calculators, push-
button telephones, combination locks, and digital door locks, which require mainly
numeric input.

19. • CAMERA
• A camera is an optical instrument used to capture an image. At their most
basic, cameras are sealed boxes (the camera body) with a small hole (the aperture)
that allows light in to capture an image on a light-sensitive surface (usually
photographic film or a digital sensor). Cameras have various mechanisms to control
how the light falls onto the light-sensitive surface. Lenses focus the light entering
the camera, the size of the aperture can be widened or narrowed to let more or less
light into the camera, and a shutter mechanism determines the amount of time the
photo-sensitive surface is exposed to the light. The still image camera is the main
instrument in the art of photography and captured images may be reproduced later
as a part of the process of photography, digital imaging, photographic printing. The
similar artistic fields in the moving image camera domain are film, videography,
and cinematography.

20. • CONCLUSION
• After testing the system developed, we came to know that ATM prototype can
be efficiently used with fingerprint recognition. Since, password protection is not
bypassed in our system, the fingerprint recognition done after it yielded fast
response and is found to be of ease for use. Fingerprint images cannot be recreated
from templates; hence no one can misuse the system. LPC2148 and FIM3030
provide low power consumption platform. Speed of execution can be enhanced
with the use of more sophisticated microcontroller. The same hardware platform
can be used with IRIS scanner to put forward another potential biometric security to
the ATMs.
