FINGER PRINT BASED ATM WITH PASSPORT VERIFICATION : ECE FINAL YEAR PROJECT

FINGER PRINT BASED BANKING SYSTEM         

  The main aim of this project to provide secure banking system, by taking fingerprints as authorized identity at ATM/banks.

             The purpose of the project is to provide a secured and reliable environment to the customers for their banking transactions by providing a unique identity to every user using the FINGER PRINT identification technology.

              Here in this project we are going provide the at most security since it is taking the FINGER PRINTS as the authentication for our account. So whenever we want to access our account first we have to press the finger on the finger print scanner. Scanner is interfaced to the micro controller with the serial interfacing. The micro controller reads the data from the scanner. The micro controller allows those users, who are authorized to operate the account. If any unauthorized user tries to operate the account the micro controller switches on the security alarm. The total information about the account holders is stored in the EEPROM. Keypad is used to enter the password to operate the account or Locker.

                In present days, computer becomes a main part of human beings for storing information. This information is up to some extent is a secured one. For example the details of employees and students etc... The authority person may only change the details. For this protection we are going to provide a PASSWORD for the PCs. This is secure up to some extent only because there may be a chance of revealing the password or sometimes the authorized person may forgot the password. So we have to provide security for PCs with a unique and simple to remember identification. One of such identification is the FINGER PRINT.

                Fingerprint Scanner is a device for computer Security featuring superior performance, accuracy, durability based on unique NITGEN Fingerprint Biometric Technology. Fingerprint Scanner can be plugged into a computer separately with your mouse. Fingerprint Scanner is very safe and convenient device for security.

After selecting the mode of operation, the optical sensor takes the finger print and compares with the previously stored database. If the present finger prints matches with any one of the previously stored data then the controller sends a signal to enable the keypad.

For each key press a low logic value will be present at the concerned pin of the microcontroller and by reading this value the controller will do the further actions as specified in the program. The concerned transaction by the user is loaded in the external memory in this case what we are using is EEPROM of 2K bytes at a particular location in the memory.

All these functions which are performed by the user are simultaneously displayed on the LCD. In case any of the finger print is not matched with the data the Locker system is not opened and the Keypad is not enabled at all by giving the indication in the form of buzzer.
