The NFC Ring is a stylish accessory which gives you the power to open doors, unlock your phone, share data with others and receive payments with a wave of the hand (sorcery!).
As you might have guessed it uses NFC technology, or Near Field Communication, to interact with other devices wirelessly. This is the same technology that is used in debit cards or smartphones to enable contactless payments.
This smart ceramic ring is waterproof, available in black or white, and comes with two NFC tag inlays, one for public information and one for sensitive data. The ring was created by John McLear and crowdfunded via Kickstarter, with 7,665 backers having pledged more than £250,000 (over two campaigns) since 2013.
