Why Biometrics ?
Biometrics authenticates and determines an individual’s identity by utilizing the uniqueness of his or her biological and behavioral characteristics. Other authentication methods often used are PIN method and Token (ID card) method. Biometrics is superior to PIN or Token methods in the following ways:
1) Increased Security
Biometrics offers superior security than PIN or ID card. Biometric methods do not involve danger of information exposure like PIN and ID card do and unauthorized persons cannot attempt to steal or make a guess at private information.
2) Increased Convenience
Today, people have to remember many passwords. They should be able to provide their passwords whenever they use their credit cards or log into various sites on the Internet. Uniform passwords can lead to serious dangers if exposed. However, biometrics does not require us to remember our passwords.
