WinCC OA 3.14 RFID Implementation

[lbonassin]

The current method of signing in to use the application is with a pop-up keyboard; the user simply punches in their name and password.

I want to implement an RFID card reader into this app so the users can just swipe their card to provide authorization.

I'm looking for the ideal method to do this. I'm quite new to WinCC OA, so I'm sure there are many features I'm not currently aware of.

I'm thinking of having a text file in the application with all the authorized users, then have the app compare the RFID tag to that list. If it's on it, access is granted.

How would you approach this task? Suggested methods?

Thank you

On a Linux system you can use PAM (pluggable authentication module) for implementing any kind of authentication check, which WinCC_OA uses with the CTRL functioin verifyOSUser().
I once implemented a PAM module to check a fingerprint reader, with which I could then login into the WinCC_OA application (as PAM works on the OS level and WinCC_OA uses just the mechanism, there's no need to change anything in WinCC_OA itself or the project).

This is going to be very helpful!
