Are you a connector? Are you always handing out business cards, sending people to your Etsy store, your blog, or your product? Do you meet people at festivals or conventions and need an easy way to connect, and stay connected? This tutorial is for you.

With an NFC tag and a few clicks in a smartphone app, you can create a necklace, necktie, hat or costume piece that not only makes you look sharp, but also helps you connect with your people. Simply tap your necklace to a smart phone with NFC technology (which is most of them, these days) and your contact info will appear on their screen like magic.

Or, set up a Venmo link on your NFC tag to make a tap-to-pay sign that's even easier for your customers to use than a QR code. NFC tags offer so many possibilities.

Parts

Adafruit carries a lot of different NFC tags in various formats. For this tutorial, be sure you're getting one that's labeled NTAG2** instead of "Classic" -- the newer NTAG2 devices work with modern smart phone apps and the classic tags don't.
