How to Make an NFC Ring
About
So you have a situation that always comes up at the end of your conversations:
Let's connect?
What do you do?
Can you unlock my computer in one tap?
Well, maybe you don't get the last one as much. But if you happen to, I'll show you exactly how to create a ring that can instantly solve all three problems with one tap of your ring.
What is NFC?
NFC stands for Near field communication. It's a form of RFID and the way it works is pretty cool. It never needs to be charged, because whenever it comes in contact with a reader, its able to power it just long enough to send whatever information is stored on it.
There are so many different types of tags, and smallest ones I could find are these chips by Adafruit, which are the perfect form factor for rings.
They also sell this button nfc, and I'm still trying to find a good use case for it because I just want one.

2. Print the enclosure
Included are the inner and outer part of the enclosure. Print both.
3. Embedd the NFC chip
There is a guide line to help line up the ring properly. Place the chip in the slot on the outer ring, then slide in the inner ring.
The black circle on the chip should be facing up. The ring should click into place.

Not really but you now have a pretty cool way to share your links, and so much more (coming soon)
