There's one very big difference between biometric authentication, like fingerprint scanning or iris recognition, and more traditional password based security.
Potential applications include face, fingerprint and iris recognition for high-tech security as well as navigation systems in self-driving cars or industrial-product inspection.
Electronic scanners would search for suspicious behavior, inappropriate clothing or individuals on wanted lists who can be identified through facial or iris recognition.
With advances in technology, a number of critical infrastructures are adopting access control systems integrated with biometric technologies such as fingerprint and iris recognition.
