FINGER PRINT BASED ATM AND LOCKER SYSTEM FOR
MODERN SECURED BANKS
Abstract:
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.
