Question about biometrics. You say that the initial phase will be fingerprint authentication and then move to vein authentication, what is the reason for doing so?I have had experience of entering a room using handprint authentication, but at that time it was a combination of handprint authentication and a PIN using a ten-key keypad. Is there a need for a combined operation of vein authentication and passwords, etc., depending on the importance of the subject for which authentication information is used and the restrictions on the disclosure of information linked to the authentication information?
