NFC Ring smashes crowdfunding goal with 2,100 backers in just four days

John McLear's NFC Ring

A UK-based startup raising funds on Kickstarter for a finger ring that lets users unlock NFC-enabled doors and devices and share information via NFC has amassed pledges totalling almost double its £30,000 (US$46,000) target in just four days.

The metal NFC Ring contains two tags. The first is designed to enable users to share information and is embedded in the top half of the ring. A closed “fist bump” action is then used to share data. The lower half of the ring includes a second tag that stores private information, such as the unlock password for an NFC device. This uses an “open palm” gesture for interactions. An app for writing actions to the tags has also been developed.

The NFC inlays each contain an NTAG203 chip which is coated in RFID reflective material and a clear RFID passive coating. These work together to ensure the metal of the ring does not absorb the RFID signal from an antenna.

Creator John McLear and his team have worked on the ring for over a year. The Kickstarter project launched on 20 July and still has 26 days to run but has already exceeded its target by more than £29,000 (US$44,500) thanks to 2,100 backers. Standard rings cost £22 (US$34) while larger Alpha rings are £25 (US$38). A do-it-yourself 3D printing option is also available for £8 (US$12).

Samsung Galaxy S4 and Blackberry Z10 users will require this larger ring due to the position of the antenna on those handsets, McLear says.

The NFC Ring has a number of advantages over other recent NFC accessory announcements, such as the Geak ring, McLear told NFC World. “Plastic rings aren’t the best material to work with as they tend to be quite big and ergo can be uncomfy, we moved away from large rings a long time ago due to this,” he said.
