Biometrics is an authentication method based on the recognition of unique biological features such as the fingerprint or iris pattern in the eye. The face, voice and veins of the hand are also suitable for biometric authentication.
The biometric functions of smartphones can now also be included in the opening process. The same level of security can be achieved through the combination of an app and an RFID opening medium (e.g. card or key fob), which are often already used by customers.
