I've tried using Tasker and Trigger, none of them can read the nfc tag in the ring.
When i pop the back off the phone and expose the battery i can read the ring only if i force it into the battery. Nothing happens if the back is on the phone, even if i hold the ring in the same spot. So it works, but it's weak, especially considering the Alpha was supposed to work with the S4 like any normal ring.
