WinCC OA Login with id cards

[RudiKreiner]

We have a customer request to configure a WinCC OA system with id cards to identify the user with which to start the UIs with instead of passwords.
The customer wants to use the same cards that his employees are already using for access control on his premises and recording working hours.
Has anyone out there ever implemented such a system or at least tried to?
I would welcome any information about how this was done and what needs to be considered.

I once did a test with a fingerprint reader for logging into a UI manager with the login panel.
I did this on Linux where I can configure PAM (pluggable authentication module)
to use nearly anything to do authentication, and use the CTRL function verifyOSUser() to actually call
the PAM authentication.
