The A to Z of biometrics

Universality

One problem with the widespread use of biometrics is that there are few biometrics - apart from DNA - that everyone has.

This becomes more of a problem when enrolling large populations into such a system. Given a large enough group there will always be people missing fingerprints, irises or other biometrics.

Many large-scale biometric programmes will therefore use more than one biometric, such as fingerprint and face, in order to ensure everyone can be enrolled.
