Program the RFID/NFC Smart Ring to open a URL on smartphone

Post by notasausage »

I'm relatively new to the NFC/RFID programming space and I'm curious about whether it's possible to use the new NFC/RFID Smart Ring as a way to share a URL with someone by having them tap their phone to the ring in order to open up a website. I'm thinking of having a way to share my website, LinkedIn profile, or some other URL with folks I'm talking to at networking events or conferences rather than carry around a bunch of business cards.

Is this possible, and if so, what do I need besides the ring to program this to happen?

Thanks in advance!

The Adafruit guide "Using Web NFC" describes how to write data to tags and read it back. Which is pretty close to what you are asking about.

A QR code would probably be the easier way, but take a look:
