fingerprint based bank locker system
DESCRIPTION
NOTE: it usually takes some time to reply to your queries because i have a lot of work and i'm not on scribd frequently so please be patient. thanks 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. 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. When this module is interfaced with the microcontroller, we will be using it in user mode. In this mode, we will be verifying the scanned images with the stored images. 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 with 8051 microcontroller. By using this controller we will be controlling the scanning process. After scanning has been completed, the person has to enter his unique id to open his locker with the help of a keypad. Immediately the locker will be opened. After the work has been completed, the locker will be closed again if a switch is pressed. If an unauthorized person tries to scan his image, then an indication will be given by a buzzer which is interfaced with 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.TRANSCRIPT

DRAW BACKS OF PRESENT SYSTEM
Security is less
Others can steal the user’s entry key

MICROCONTROLLER
89S52 microcontroller.
RAM 256Bytes.
8Kb of flash memory.
The functionality of 89S52 is
same as 8051
microcontroller.

FINGER PRINT MODULE
In this we choose “verification” process.
It can operate in 2 modes they are Master mode
and User mode.
9
MASTER MODE
In this mode,we can register our finger image in present
of manager.
10
USER MODE Compare of input finger print and identified finger
11
LCD
We are using 16x2 lcd display
LCD has14 pin

13
PASSWORD PROTECTION
Unique id (password) which is given to user to open
his locker with the help of a keypad
Any port was used to handle our alpha-numeric
keypad.
14
15
STEPPER MOTOR
Automatically, locker will open by stepper
motor(step angle).
After the work by using reset pin user will secure
their locker.
16
17
Buzzer It is a signaling device.
It beeps when user mismatch.

ADVANTAGES
Most secure
No manual errors
Need not carry any
card
Others cannot
steel the user’s
entry key20
APPLICATIONS
Voter Identification and electoral enrollment
Industries
Banks and ATM
Personal Computer
21
SCOPE FOR ADVANCEMENTS
GSM modem can be connected to this unit to communicate
to security department, in case of unauthorized entry trials.

CONCLUSION
This project is used for 100 members, we can also
extend the capability for further requirements.
