Hi everyone,
Just letting you know that the ASUS NFC express, which was previously crap, is now much better since the most recent updates of both the driver NFC_Driver_Win8_1_VER1461 and the application NFC_EXPRESS_Win8-8-1_VER10019
Strangely this also worked from my Lenovo Thinkpad Twist, as well as my asus motherboard.
It should be noted that the ASUS software, like the NFC ring unlock app, writes to the tag instead of just reading it. So the private side of your ring cannot unlock both your desktop and your phone (annoying)
Just letting you all know
Cheers Jason
Disclaimer - I don't have my ring yet so I'm testing with other tags.
