We added a curved slit in the center of the bridge so we can insert the tag.

Fine tipped tweezers help insert the tag into the slot. Make sure to orient the chip so it’s facing towards the head of the ring.

Writing data to the tag

NFC Tools is an Android app that can be used to write data to the tag. You can write contact information, trigger actions like loading a website, or application and you can even assign custom tasks.

To trigger actions on the Nexus 7 tablet, the tag has to be pointing between the letter “N” and "E".

For this demo, we thought it’d be cool to fire up a video on YouTube, but you could use it to store contact info like a business card!

And that’s it! A really easy way to embed RFID tags into 3D printed things.
