I was a KickStarter backer for the NFC Ring project and just received my first ring and have a few others ordered to support the NFC Ring team. I was excited to use it but my GS4 is having NFC issues. Has anyone tested out the NFC capabilities of the OPO or have any of you bought/tested an NFC Ring. What are your thoughts on both? I like the idea of having NFC tags for different things, like setting your phone to work/sleep/driving modes, but since there isn't NFC integration into the stock lock screen (only a secondary NFC Ring lock app, which is very buggy) having a wearable tag doesn't seem very useful right now.
