Biometric technology is set to encompass nearly all aspects of the economy and our daily lives. Utilizing biometrics for personal authentication is becoming convenient and considerably more accurate than current methods (such as the utilization of passwords). This is because biometrics links the event to a particular individual (a password or token may be used by someone other than the authorized user), is convenient, accurate (it provides for positive authentication), can provide an audit trail, and is becoming socially acceptable and inexpensive.
