I think bank security is being developed following the current way of using biometrics. The problem of a password is copy = copying and hacking. That's why banks have tried to use the biometric = biometrics. As we know, it is only one thing. But it is not perfect. there = There are two point = points related to using biometric = biometrics. First is sensing the personal bimetric = biometric information. If it is not well detected, it is annoying to use and it is possible to be breached. Second is data. Despite using biometric information, that data is stored in a server, so hackers can steal that data in server. In line with that, using biometrics is the same as the current trend, and using data will be changed, not saing = being saved in the server, instantly serching = searching information will be used.
