This document proposes a biometric-based secure access system for bank lockers that uses fingerprint authentication for security. The system contains a microcontroller, keypad, biometric fingerprint module and LCD display. It works by requiring users to enter a code via the keypad to open the locker door initially, then authenticate via fingerprint to access the main locker compartment. This dual authentication provides better security than traditional systems and can also track unauthorized access attempts to alert banks.

1. Bank locker system

2. • In today's modern world, security plays an important role.
• Every person has precious accessories like gold, jewelry or cash.
• It is not enough to have these accessories, but security of this is very important,
for this purpose we keep them in bank lockers.
• Still we often hear or read in newspaper that some fake person has access the
locker of another person and have stolen money.
• In order to overcome this type of frauds, authentication of the person who wants
to use the locker is very important.
Introduction

3. Objectives
Banks offer locker facilities to individuals as and when required Both public as well as private sector banks
offer this facility to needy individuals for a small annual fee These lockers are maintained in a secure facility
that is under constant surveillance and security There are several advantages of availing a bank locker, a few
best ones are listed as follows:
• Softy.
• Easy access.
• Available in any bank branch.
• Anyone can avail.
• Nomination facility available.

4. Proposed system
• In this project we propose a Biometric based secure access which can provide a sophisticated
theft alert system for bank locker system.
• This system contains microcontroller, keypad, Biometric module and LCD display.
• By using keypad we need to press the button to the three door opening purpose.
• Then using biometric module to open the main door for authorized person.
• This system offers better solution for the bank security system and it will also help us to
track the person who tried to open the locker without the permission and proper
authentication.

10. Characteristics of
Biometrics
 Any human characteristic can qualify as a biometric characteristic as long as it satisfies the
following requirements:-
 Universality
 Distinctiveness
 Permanence
 Collectability

11. Working of Biometrics System

12. Fingerprint Recognition
 A fingerprint is made of a series of ridges and furrows on the surface of the finger.
 Ridge ending, ridge bifurcation and minutiae points.
 Algorithm is developed to distinguish whorl, arch and loop.

13. Fingerprint authentication

14. GSM Modem
• GSM modem is the Data Communicating Equipment which is connected to terminal equipment for
data transmission and reception.
• GSM stands for Global System for Mobile Communication
• SIM stands for Subscriber identity Module
• GSM modem is controlled using AT commands
• AT stands for Attention
• Ex- AT, AT+CMGR, AT+CMGS, AT+CMGD etc.

15. AT Commands & Corresponding Operation
AT Commands Description
AT To check if Modem is
connected properly
ATE0 To turn echo off
ATE1 To turn echo on
AT+CMGF Set operating Mode

16. AT Commands & Corresponding Operation
AT Commands Description
AT+CMGD= <index>,
<delflag>
To delete a message
AT+CMGR= <index> To read message from an index
AT+CMGS= “contact no.” ,
TP-type address
To send message to specified
contact no.

17. Enable (E)-This line allows access to the display through R/W and RS lines. When this line is
low, the LCD is disabled and ignores signals from R/W and RS.
When (E) line is high, the LCD checks the state of the two control lines and responds accordingly.
Read/Write (R/W)-This line determines the direction of data between the LCD and
microcontroller. When it is low, data is written to the LCD. When it is high, data is read from the
LCD.
Register select (RS)-With the help of this line, the LCD interprets the type of data on data lines.
When it is low, an instruction is being written to the LCD. When it is high, a character is being
written to the LCD.

18. •A relay is used to isolate one electrical
circuit from another.
• It allows a low current control circuit to
make or break an electrically isolated high
current circuit path.
