Biometrics assures identification of individuals at a very high level of accuracy and is used in high-security areas such as banks, institutes, important government organizations and various airports.
The biometric technology is clearly making rapid technical advances. The first thing to be discussed here is technical limits. One cannot safely assume that the technical limitations of biometric identification protect our privacy today.
Moreover, even if the “technical limitations” argument were sound(Alterman, 2003)., there are reasons to think that this only creates different kinds of privacy concerns. For example, Veristar requires a 7-digit code "to empower prompt location of your biometric ID" on the off chance that a Smart Touch fails. The company recommends using your telephone number as the code.
