Theres lots of info here on using the rings with Android etc, but what do you use to write to the rings?

Ie: How can i write a text file or something to one in windows?

Despite starting the thread i havent check back for ages. Was about to finally look buying a reader/write, and was thinking the HID because of the reputable brand name, lucky i did!
Might look at getting one of the ACR's instead.

But am looking forward to seeing what solution you come up with !

Seems a bit of a waste of ring functionality to just store recovery keys that would hopefully never be used.

But, i guess a minidriver to use it as a smartcard might be a good suggestion for a future piece of software.

Why would the tag on the ring be treated any differently to the tag on a smartcard?

I only know the basics about smartcards and NFC so am genuinely trying to work out if its possible to do what i want to do,
I have no doubt that I can store a certificate on a 2016 ring, there is space. But whether it will be treated as a smartcard as far as windows is concerned, i dont know.

The ACS one seems easier to buy than the HID, since Amazon wont send one to me in Australia!

Im not really interested in using it for Windows logon, theres plenty of software that will do that. Lafunamor, does it allow your NFC Ring to present as a smartcard?
I plan to store a certificate on a 2016 ring once they're available. A self signed Windows certificate for bitlocker is 778 bytes so am hoping it will treat the ring as a smartcard.

A lot on here about what people store on their rings, but not a lot on what they use to do so. Android devices are easy since NFC is built in to most phones and tablets these days, but what about from a Windows PC?

Ive seen the Asus NFC express mentioned, but im looking for something small and portable, preferably in a USB stick format. Found a few on Amazon, does anyone have any experience with these? What do others use?

Thanks

I did a bit testing since i had some spare time, and a self-signed windows certificate for bitlocker that i created came in at 778 bytes. Looks like it will fit on the 2016 models with a whole 110 bytes spare!

Well like i said, to me it would be useful as an encryption key for unlocking things like Bitlocker volumes. Bitlocker supports certificates on smartcards, so an NFC ring treated as one, would be great.
Very hard to lose, even give a level of deniability if no-one can tell thats what the ring is.

Im looking at getting an NFC ring, havent quite decided on whoch style yet, but one of the things id like to use it for is to store a certificate.

Windows Bitlocker and other similar applications can use certificates to encrypt files/volumes, and those certificates can be stored on smart cards. Assuming i have a suitable NFC reader on my laptop or desktop, could a certificate be stored on an NFC ring to be used as a smart card?

Thanks.
