Overview

In this project we’re embedding an RFID tag into a 3D printed ring. 

The micro RFID NFC tag is incredibly small and yet flexible enough to be embed into all sorts of objects.

It features a NTAG203 chip plus antenna and contains 144 bytes of read-write memory. It works with almost any NFC capable tablet and has secure 8-byte user ID.

Although we carry NFC/RFID rings in the shop, it’s much more cost effective to 3D print one and you can also customize it to any size or shape.
