I primarily use Linux, and wrote my own scripts to log in, and lock/unlock sessions (https://github.com/Giraut/nfcutils). Under Windows, I use Rohos Logon Key for machines on a domain (not free) and ISLOG Logon NFC Community for standalone machines (free).
I posted a slightly more detailed writeup of what I have going, including a couple of videos, in this thread on the biohack.me forum: https://forum.biohack.me/index.php?p=/discussion/2715
(I hope it’s cool to link to another forum. Otherwise, my apologies and feel free to delete my post…)
