Abstract : In this project we have done on biometric authentication system that is finger print authentication system. Biometric authentication system is used for different purpose in place of visa cards or automated teller machine (ATM) cards because of the visa or ATM card and the password is forgotten during a person travel from one place to other place. Due to difficult to remember and memorize of this two things (visa cards and password) we design this biometric authentication system, since biometric authentication system is safe and secure, unforgettable and also very easy to use everywhere. Biometric authentication system is reliable, economical, save time, and has more advantage compare to other like visa cards. The user suspect their password may be stolen or attack by thief then the user change their password when they expect the password attack by the thief. In order to solve this kind of problem we design biometric authentication system (finger print), because biometrics is the science of using human measurements to identify people. This technology not only make our lives easier and simple by reducing the required to carry identification but also it prevents the use of forget visa card or ATM and passwords . Biometric is selective because of why? It has unique characteristics that is no one shares and remain the same over time . In this project we have survey on biometric authentication system. Biometric authentication system is used for various kinds of authentication system instead of the tension of cards to put with them and to memorize their difficult passwords and pin numbers. Biometric authentication system is much safe and secure and very easy to use and even without using any password or secret codes to remember as compare with previous system like credit card payment system ,wireless system and mobile system etc. Biometric authentication system is reliable, economical and it has more advantage as compare with others. In daily life the usage of credit cards, check cards for shopping, bus card, subway card for traveling, student card for library and department , and many kinds of cards for unlimited purpose and so on. So problem is that a person has to take many cards and has to remember their password or secret codes and to keep secure to take with it all time. So the biometric authentication system will solve this problem. Greater adoption of biometric authentication system will drive down the cost of biometric readers and thus making it more affordable to small business owner .
