Before you can do any of the NFC cleverness you need to register the ring with the app. The main app that you use is called NFC Ring Control. This is where you write the different NFC actions to the ring. These include creating links to Twitter, Facebook, Youtube and writing text. Now this isn't what I bought the ring for, and to be honest I can't see that I would ever use these functions. Sharing my facebook profile or twitter account with someone isn't useful to me, but maybe if these were used in a promotional way I can see the use.
The second app you need which goes hand in hand with the previous app is called NFC Ring Unlock. This is where you get all the settings to refine the NFC unlocking process. I have to say that the apps provided at the moment by the NFC ring team feel quite beta ish. I'm pretty sure there will be updates in the future but in the meantime I use an xposed mod on my rooted LG G2 which has a smoother implementation.
I bought the ring for the primary reason of a secure and fast way to unlock my device. The NFC technology at this time isn't quite up to speed. One of the problems with unlocking the device is finding the 'Sweet Spot', where your antenna in the phone is at its strongest. When you set up your ring with the control app you are taken through a process to find the so called sweet spot. Every make of device has it's antenna in a different spot. You basically move the ring around the back until the phone recognises it. Mine happens to be right and below the volume button. That's what the stickers are for, so you can easily locate the sweet spot. You also have to be 99% accurate as well when trying . In my week of trying to use the ring I found it to be very temperamental and wasted plenty of time swiping over and over to get it to unlock. Maybe there is something that the software updates might be able to help with but i have a feeling I'll have to wait and see if future phones have bigger and better NFC antennas in.
I'll finish with a little write up of the rings pros and cons that I found. The finish on the ring is excellent and the open NFC tags gets a lot of funny looks from my friends. I think it could have many useful applications. I like the idea of having your phones apps being independently locked down and needing the ring to get into them, messages or gallery perhaps. One of the uses the uses the NFC ring site advertises is to use it in conjunction with an NFC door lock. I haven't got one and probably not many people do, but if I had the option to install one I probably would.
The only real negative is the hassle of trying to line up the ring with the antenna. I found this to be a real deal breaker to use it, and often found it easier to just type in my password or pattern unlock.
I'll be keeping the ring to see where it uses go in the future, I just wonder how long I wear it before it ends up gathering dust on a shelf.
Please share your thoughts, feelings and good uses for the ring. Whether you have one or not, and please +1 and share.
