Hi @p6ril yes you may.
I have rings and cards registered on both my phone and tablet, they work fine on either device.
The unlock app registers your UID in the phone. The part that is written to the ring is actually just an action trigger basically, with the UID making that one allowed to trigger the unlock.
You can also use the same ring with an arduino reader that doesn't alter the stored info, just reads the UID, or a door lock that operates off the UID.

glad I could help. this is a bug which will be fixed with the next version.

Well, glad it got working for you at least.
There are looking to be changes in the way validation works in the future.

@Lafunamor yeah, in NFC Ring Control version 0.1.11 the language problem is gone.

I'll wait until after Google I/O

That one's difficult @lobi, because the unlock app is trying to do things purely in userspace that are a lot easier with root access. It's bringing the NFC unlock to the people who for one reason or another aren't using rooted android devices.

Would you care to elaborate a little? Device, OS version, etc?

I believe there are some apps in the Windows Store. But we have some user working on a NFC logon.
Checkout this threads:
Asus NFC Express
NFC reader for passwords
There is one about developing an own NFC login solution for Windows but I don't find it.

Hi @FrankyD, that's the Unlock app, not the Control app.

Our contacts at Google were not willing to say if it will/wont support NFC... Anyone able to dig further?

I did, but I think that there is a flaw with the Android control on the Nexus. I tried a different app using the same control and it had the same problem. The add icon with the key and the plus brings up the dialog box but the bottom half is chopped off and you have no choice but to cancel. The app that I used successfully had a different UI control ( a simple add button). Obviously, it is impossible to test on all devices but this was a useful exercise as I will try to create my own app at some point. (This will be a demo for something I do at work so won't ever end up on Google Play).

Thanks!

Yes, in that case its really redundant for me. I was expecting the ring to be able to unlock the password screen of my phone. Having a popup screen in order to prevent any use of the phone don't seem like a good way to lock up the phone. I guess I will have to root the phone then. Thanks for all your contributions.

Its all good folks, turns out I was just being especially idiotic

Whenever I got past the lock screen with my pin and my Nexus asked me what I wanted to do with the NFC interaction and offered me a list of apps, I should have selected the Ring Unlock app, instead of just ignoring it...

try to pull down the quick menu

I use trigger and NFC unlock without problems, FYI

try the reset link and use an all CAPS password. this is an old bug but might still be in the release version.

i feel myself like ncfnoob :(

i changed the pin to a shorter one and tested it again. works. thanks

[SOLVED]

Resolved

@John what fixed the problem?
