At a guess I'd say the unit isn't putting out enough RF for the metal enclosed rings to work, which is a real shame. Boosting the power is a hardware hack, and not an easy one.
You might be better off going sideways and getting an arduino beetle and a PN532 reader.
I may do that, I'm just not all that confident in programming it to work.

Well, there is an example up already in another thread that shows how it can work.it just needs to be expanded upon now, maybe with a couple of modes so it can also be used as a reader/writer.

I just ordered another Asus NFC Express to test the 2016 with.. Will post results next week

@johnyma22 There are actually two models, the original and a newer one, although from what I can tell is probably the same electronics on the inside as the specs are the same, just a different shape.

2016 NFC Rings work w/ the NFC Express :)

What data is stored on the NFC Ring when using NFC express to login into Windows? Any credentials? If so, are they stored in clear text? Does AI Suite store the credentials on the system? If so, encrypted or clear text?
How I'd like it to work: Credentials are stored encrypted on the system and the nfc tag gets a "password" or key written to it which is the only way to decrypt the information. Of course using secure encryption standards as well as a generally big key on the NFC tag.
I can't find any information on how it works technically, or rather I can't find where I would find that information if it exists..
Edit: Also, does it work on Windows 10?
Edit 2: Or perhaps it could work the other way around, the encrypted data is stored on the NFC tag and the key is stored on the system, when reading the tag it then copies the data to memory and decrypts it with the locally stored key, then logs in, then clears the data from memory. That way it could theoretically work on multiple systems, as long as you have the ability to import keys... But anyway, main concern is how NFC Express actually does do it. :)

Its been a while since I had mine working, I actually broke it when i was trying to hack it to work with the 2013 ring. From memory I think it kept a random text string on the ring as a text entry.
It may have been an encrypted password, sorry I really cant remember, but I can assure you as soon as I get my hands on a 2016 ring I will be buying a new one of these and will update this thread.
Cheers. Jason

I've gotten my NFC Express today and I've tested the login function with the supplied Asus NFC Tag, reading the NFC Tag it seems to store the username and then it seems to store the password but not in cleartext, it's probably a hash or the encrypted password. It also works nicely with Android Smart Lock at the same time without having to rewrite anything, so I can use the same key to unlock my phone and computer (will be handy for when the ring (hopefully) arrives)
My system is running Windows 10 pro, so I was uncertain whether it would work or not, but it appears that it's working just fine, at least for me. I did have to install the Windows 8.1 drivers but they're seemingly working fine. Although worth noting is that I've only tried the login function so far. So while it may not have official support for Windows 10, it does seem like it works with it.
Now the only thing missing is a ring. ^-^

Awesome thanks @SanyaIV
RE It's probably a hash or the encrypted password,
It's probably a hashed key lookup so even if someone got the string from your ring they wouldn't be able to guess your password or brute force it without the key lookup table from your PC.
