So a month ago i ordered an NFC ring for myself but unfortunately it arrived a month later and as you can see from the picture above, it didn't even fit my pinky finger. I'm pretty sure i ordered the right size but, Oh Well 😔

But What Even Is A NFC Ring?
Well an NFC Ring is a ring with an NFC chip in it and NFC stands for Near Field Communication. The NFC chip can store a small amount of data with whatever you choose. You can have Url or the wifi password or even your Bitcoin address in it. I took a screenshot of all the options the app gave me to fill my NFC ring with.

As you can see you can use the ring for a bunch of different things and it doesn't even require you to charge it. The only problem i noticed is that it can't connect to my phone if it's in the cover since it's a pretty thicc rubber cover. But i still think it's a cool piece of tech and I'll probably buy another one with the right size.
