FINGER PRINT BASED BANK LOCKER SYSTEM
According to 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.
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.
The fingerprint module will be interfaced with the microcontroller through serial interface. The persons whoever comes to the banks for the first time to create their bank accounts will be asked to scan their images. After their fingerprint images are scanned, the administrator provides the user with unique ID and password. After that, whenever the user comes to the bank, he has to scan his image to prove that he is an account holder in that particular bank. Thus, the fingerprint module scans the image and sends it to the microcontroller. The microcontroller reads the image, compares the image with the already stored images in the database.
If the scanned image matches the stored image, the person is allowed to enter into the bank through the main door. The main door will be opened by rotating the stepper motor fixed to it. The door closes automatically after a small delay. If it is not matched, indication is given to alert the buzzer.
Now, for the user to access his bank locker he needs to enter the ID and password using the numeric keypad. The user can change the password at any time. When the entered ID and password are correct, the user can take the cash or valuable items from his locker. To lock the locker, the user has to press the switch provided. If an authorized person forgets his password, he will be given 3 chances to re-enter the password.
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.
