My app is registered as far as I can tell. I received the email in January, clicked the link & installed the app.
I do not however have an option for adding keys.
Only:
Create Actions
Read
Settings
Register
Feedback (which does not work BTW)

@Lafunamor
Yes, but my question is how?
It is not recognized by the app as a ring so how do I do it?

Update:

I tried the ring and tags with a Nexus 5 today. It recognizes the tags but not the ring. So I believe the ring shipped defective.

Also, when the app reads the additional tags is pops up:
"ALERT
Not NFC Ring"

So how am I use them as backup keys?

Device: Nexus 7 2013, Android 4.4.2

I fear this ring does not work. My Nexus 7 can read other NFC tags, like the ones included (btw what do I use those for?) but it will not recognize the NFC Ring.
I have tied everything I could find online before I resorted to emailing support.

I have:

• slowly covered the whole surface with both sides of the ring. Multiple times and also at different angles.
• determined it is not my device because it works fine with other tags.

What is the next step?

Thanks,

Phillip C.
