Biometrics refers to readers that can automatically verify the identity of a person by measuring its unique physical characteristics such as fingerprint, finger vein or face recognition. Increasingly, organizations are realizing that traditional user name and password solutions are a pain for users and IT and that they are no longer sufficient to manage and secure logical access. Authentication by biometric verification is becoming increasingly common in corporate and public security systems. In addition to security, the driving force behind biometric verification is the user convenience.
