Hi everyone,

I have a question regarding Siemens HMIs and NFC integration.

Has anyone here successfully implemented an NFC reader to log into a Siemens HMI using an NFC card/tag? The idea would be that a user simply scans their card and automatically logs in with their assigned credentials.

From what I understand, Siemens HMIs (at least with standard WinCC setups) don’t allow login unless you manually enter the username and password. So I’m wondering if anyone has found a workaround—maybe via scripting, external systems, or PLC logic.

Any insights, experiences, or suggestions would be really appreciated.

Thanks in advance!
