INTRODUCTION
1.1) OVERVIEW:
According 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 present scenario to operate a bank locker is with locks which are having keys. By this we can’t say that we are going to provide good security to our lockers. To provide perfect security and to make our work easier, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. In this project we are using our fingerprint and password as a key to open bank locker there by avoiding the usage of keys. There by providing security and reliability.
1.2) OBJECTIVE OF THE PROJECT:
This project is related with Embedded system technology. The main objective of this project is,To provide good security to bank lockers by using a unique module called fingerprint module. In which a person’s fingerprint is stored and identified .If at all a person has to enter a locker room ,he need to scan his fingerprint in the fingerprint scanner then after verification further he need to enter the desired password ,thus using fingerprint, password we are avoiding the usage of keys and providing good security for our lockers.
1.3) AIM OF THE PROJECT:
In this project heart of entire project is microcontroller. Many ancient methodologies have come up like signature face ,iris, voice identification, but all these can be immitated or fabricated . However, a fingerprint is completely unique to an individual and stayed unchanged for lifetime. so our project is a real time project for providing perfect authentication , we can also increase & expand security levels by using finger print technology it also consumes low power and flexible application
1.4) ADVANTAGES&DISADVANTAGES:
There are many advantages of our project because fingerprint is unique for every person it cannot be immitated or fabricated .It is not same in the case of twins also,the advantages are
• Sophisticated security
• No manual errors
• No false intrusion
• Need not to carry ant card
• Others cannot steel the user’s entry key
DISADVANTAGES
• It has less memory.
• If external memory is interface with microcontroller it takes large time to access data base
1.5) THEIESES ORGANISATION:
This project FINGERPRINT BASED BANK LOCKER SYSTEM is used for providing safety and security and to avoid the usage of keys. The present scenario to operate a bank locker is with locks which are having keys. By this we can’t say that we are going to provide good security to our lockers. To provide perfect security and to make our work easier, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS.
Chapter 1 deals with the Introduction and need for designing a system like “Fingerprint based bank locker system “and advantages and disadvantages of this system.

CHAPTER 2
THEORITICAL CHAPTER
2.1)INTRODUCTION:
This project is related with Embedded systems and bometrics technologies. The main objective of this project is,to provide safety for our bank lockers and reliability.It uses fingerprint and password as a key to open the bank locker .
When coming to our application the images of the persons who are authorized to enter into the locker room will be stored in the module with a unique id. To prove that the persons are authorized to enter that area they need to scan their images. This scanner is interfaced to 8051 microcontroller. By using this controller we will be controlling the scanning process. After the scanning has been completed the person has to enter the unique id which is given to him to open his locker with the help of a keypad. Immediately the locker will be opened. After the work has been completed if a switch is pressed the locker will be closed again. If an unauthorized person tries to scan his image then an indication will be given by a buzzer which is interfaced to the controller. If an authorized person forgets his id he will be given 3 chances to re-enter the id.
This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer,NGE-OP67 module,AT89S52,lcd ,stepper motor,keypad
