Biometrics is one kind of technology that can be used to control these kinds of fraudulent practices. May be it is the system which cannot completely stop the practices but yes at least it is the way which can reduce it to the barest minimum. The conventional methods for the security are not so strong that they can do the identification of the person; these systems will not be able to identify the person if he creates a duplicate identity for himself and goes into the bank for some fraud. But with the help of biometrics it can be reduced a lot. Biometric authentication is the method which validates the identity of the user who wants to log into the system by measuring some intrinsic characteristics of that user. This is a method which uses finger prints, voice prints or the typing patterns. It is the method which is based on some unique characteristics of the user. In other word it is the automatic identification of living individuals with the help of their physiological and behavioral characteristics. This method can easily identify the negative identification. The pin number or the some code is being reissued by the bank system but the biometric identification is never reissued.
