Check out the latest Adafruit Learning System tutorial from Erin St Blaine: use NFC tags to create a scannable tap-to-pay link or social media link that’s inexpensive and easy to use. NFC tags use RFID technology, scannable and writeable by most modern smart phones. This is a very inexpensive and easy way to connect with the people around you using technology. From the guide:
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.
