You're right, it's based off UID only, so if it can read long enough to give the failed read sound then it'll still unlock cos it'll have the UID. I played around with it for ages doing that, making sure that it wasn't just unlocking for any old device.
Something you can do that's interesting and bypasses the empty tag message is to encode an action for the ring, like in my case I read a lot so I have a good selection of ebooks and my reader of choice. Setting up the ring as both unlock-allowed and also to trigger the ebook I'm currently reading lets me unlock the tablet or phone with a quick swipe and the "failed read" sound, and with a longer "successful" read it'll both unlock and launch my book.
It's fiddly for a start but after practice it's second nature.
please follow this link and send me the email address you used and the link you received as you entered your email in the link above.
I'll set a password myself and test it so we can check if it's an error on your side or on the server side.
I'll send you the verification code if it works on my side or contact John to sort the issue out.
You download a nfc app from the play store like NFC tools and go to erase tag. Lol, but don't erase your unlock key smh. So the tags on my ring are two different tags. I should have gone with two different colors then but I'll get used to it. I love this thing.
@Twyst Afaik it's likely you are having issues with case sensitivity of your email address, can you try a few variants to see if you can find one that works? If you are still struggling bump this thread and your support ticket.
seems like you're entering wrong data as when you get the "please register" output this means that your email / verification code combination is wrong.
