NFC Ring: Rings Open Doors
Near-field communication or NFC is a wonderful standard for mobile devices. It’s more secure than RFID and a lot easier to use compared to Bluetooth. I’m not sure why it hasn’t taken off yet, but that may soon change if devices such as John McLear’s invention take off.
McLear’s NFC Ring has two NFC inlays. The idea is to use one for public purposes while the other one is for private applications. So what can you do with it? For starters, you can install NFC-enabled door locks like Lockitron at home and forget about carrying keys. Just tap the ring to lock or unlock your door.
You can also do the same if you have an NFC-enabled mobile device.
Each inlay can store up to 144 bytes of data, enough to share links to websites or personal data.
Pledge at least £22 (~$34 USD) on Kickstarter to get an NFC Ring as a reward. If you have access to a 3D printer, you can print your own ring then pledge just £8 (~$12) for the NFC inlays alone. Or forget the ring, pledge for the inlays then embed them in your skin.
