Silver RFID Ring

This tutorial demonstrates how to make a silver ring that holds a glass RFID tag. It’s the same kind folks get implanted in their hands to unlock things like door, computers, or vehicles. I’m not quite brave enough to get the implant but I do like making jewelry and wearing rings, so this solution is perfect for me.

I got these tiny glass ampoule tags and RFID reader from Trossen Robotics– they are the daintiest tags I could find. Normally when mounting a stone on a ring, it’s surrounded on at least one side by metal. I was worried the standard bezel would impact the tag readability, so I wanted to create a design that would allow the most possible open space around the tag. I prototyped the design without a tag, just to see how comfortable it was before scaling up to add the extra pieces and figure out the construction.
