Project Name: NFC Ring
Currently Funded: £124,000
Deadline for Pledging: 19 August 2013
It's your business card, house key, wallet, and more: This NFC ring (near-field communication) works in union with other NFC-enabled devices to simplify your life. For instance, you can touch your palm to the backside of your smartphone while wearing the ring to unlock it without having to punch in your pin. Wave your hand in front of your NFC-enabled door lock for easy entry. Share your website, Wi-Fi password, or Twitter handle with friends old and new. You can even share your public bitcoin address to collect payments.
The ring features two small transmitters: A large one on top that broadcasts public information, and a smaller one on the bottom that transmits private data. Bradford-based project creator John McLear designed the inlays this way to ensure your private data stays secure, so you only share when and with whom you want. Because it uses passive NFC, the ring has no battery and needs no charging.
Programming is done through apps, including some third-party apps. McLear is creating open source software, developed in Apache Cordova, so third parties can tap into the platform.
For £22 you can download the app and get a ring delivered to your doorstep this September. If you're a "big beefy chap" with "huge grizzly bear throttling hands," you'll likely want to spend the extra few pounds to get the Alpha Man Size Ring, which is 12mm wide and also works with the Galaxy S4 and BlackBerry Z10. Have access to a 3D printer? For just £8 you can print your own ring and receive an NFC inlay in the mail.
