One side of ring stops working



  • I received my ring a few days ago, and love being able to unlock my door and phone with my hand; very convenient. Half the fun died when one side of my ring stopped working yesterday. At first it would only work about half the time, then it stopped working completely. My phone, a Galaxy Note 2, can no longer read that one side, nor can the Adafruit PN532 breakout board. The other side of the ring still works flawlessly across devices.

    Has anyone else experienced this problem?



  • @Taylor This happened to me too. But it did not give any signs before the one side did die. It just died after half a day of "use".
    Anyway. The NFCRing Team offered great support and response regarding this matter! :D

    Hi Taylor, that's no good. Could you drop <!-- e --><a href="mailto:support@nfcring.com">support@nfcring.com</a><!-- e --> a line and let them know that one of your inlays has stopped working, they should be able to sort you out.

    Hi Taylor,

    Send me a message on here as well if you can. I'm currently in transit to China at the moment, we will get you a replacement ring sorted though.

  • Aaaand there goes the other side of the ring. I'm really hoping my ring just happened to be part of a bad batch that slipped through QA. I've absolutely babied my ring since the first side failed, just to be certain I didn't lose the other chip. Time to go through the returns process!

    That's very unusual. Are you working/living in a area where there is a lot of radio waves? Unless you rewrote the tags the whole time they should last for years.



  • The office I work in has 10 wifi signals stronger than -80 dBm. That would be the worst my ring is exposed to. As for re-writes, I'm at two for one side, 5 for the other. The failure of both sides did not correspond with a re-write.

    I really can't see that overloading the NTAG203.
    I've exposed mine to far, far worse in the kiloWatt range without killing them.
    Did you message Tom on here as well, Taylor?



  • I did; left in his hands. Thanks for reminding me about that. I would have started the replacement process all over again.

    so you'll get a replacement soon.

    Would the ring be more susceptible than your average ntag? I've had one on a keychain for nearly a year with no issue and a few sticker tags at my house and one at my office that still work fine.
    I live in Chicago, so I would imagine the area is quite saturated with radio waves, especially in high density residential areas where everyone and their mother has wifi. My 2.5 ghz wifi has degraded performance and my apartment is on a street that is more commercial than residential.

    It really shouldn't be any more susceptible than a standard style tag, and I'd think it would be a little more hardy than those by dint of it's titanium construction.
    I have had an inlay die on me, but I honestly think it just randomly stopped working rather than actually being damaged by my shenanigans.
    While I wasn't able to use them properly last time I was at a television broadcasting tower, I wasn't able to use my phone or commercial radio either. All these issues resolved themselves once I was out of that RF field. Note that it was somewhere around the 20 kilowatt range, so it wasn't unexpected that it would drown out everything.

    Actually I have a theory about this, I think the factory are putting some superglue on the titanium band which is sticking to the glue holding the IC in place and when the ring takes a heavy knock there is no "space" for the antenna to flex into causing the IC to break away from the antenna.

    The glue isn't on our spec sheet but the factory have admitted they have been putting it on to "make production easier". I'm chasing them about it at the moment and trying to get to the bottom of it. I expect if it's the case the factory have gone off piste again we will have to replace any rings that go faulty..

    What are doing though is if your ring goes faulty only on one side we can do you a new ring at a heavy discount, email us for details :) This way you don't have to send it back in for repair, best of both worlds!

    That's kinda awesome, yay China.
    It would explain why I can sometimes get the faulty inlay to read after 'massaging' the inlay cover. I guess I'd be occasionally pushing everything down just the right way to make contact again.

    Here's a curious question for you, John; would it be worth looking into the idea of a DIY inlay replacement/re-finishing kit at some point?
    I can understand that it could be difficult in the case of something like the dreaded carbon fiber but from the ones I have here it looks like the black and the blue at least have the colour in the epoxy coating. I've managed to pretty spectacularly gouge the black side of my Alpha ring and though it does still work it's fairly deep. The black side on my Normal ring is the one that has failed but still intermittently functions when I apply pressure in the correct spot, I guess because the chip as you said has seperated itself from the antenna. This one would be a good candidate for an inlay replacement kit if that were ever to be available - I'm not afraid to give it a try.
