If you are looking for domain support, you might try using the built in smartcard framework for windows login. You might be able to use the xNT with it, or maybe not. If not, you should try working with the NFC Connector linked above along with this reg file;
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais\SmartCards\Dangerous Things xNT]
"Crypto Provider"="MySmartLogon NFC CSP"
Copy everything between the === lines and put into a xNT.reg file, then run the file to import the changes. That should ensure the xNT is seen as a "smart card" by Windows and it will also ask the NFC Connector to process the "card". I've not attempted this myself, but it may work for domain accounts. If not, then I'm sure the full EIDAuthenticate product will work with domain accounts just fine.
We are looking forward to the release of VivoKey, since it will work with the Windows smartcard framework directly.
