Summary of Project: Embedding RFID Tag into 3D Printed Ring Watch the full guide on: https://learn.adafruit.com/3d-printed-rfid-nfc-rings We're creating a project that embeds an RFID tag into a 3D printed ring. The micro RFID NFC tag is incredibly small and flexible, making it easy to embed into various objects. It features a NTAG203 chip plus antenna and has 144 bytes of read-write memory. This tag works with almost any NFC capable tablet and offers secure 8-byte user ID. It's more cost-effective to 3D print an RFID ring than buying one from the shop, and you can customize it to any size or shape you need.
