i have implemented a PAM module that logs user in according to login information written on NFC-Tags. i can log in via GDM or KDM with checking data on nfc tag and corresponding information on Ubuntu.
Here is my question:
how can i bypass (GDM or KDM) login screen and log user in just with detecting and checking login infromation stored on NFC-tag?
Example scenario:
When Ubuntu started, user put his tag on nfc reader and log in without any interaction with login screen.

Thanks in advance.
