A new smart ring is able to unlock laptops as well as make contactless payments and even be used as a key to access office buildings, homes and cars.
Token Ring, created by start-up Token, has near-field communication (NFC) compatibility and Bluetooth connectivity built in, meaning it can be used as a contactless payment device or smart key for a range of products.
That includes homes, cars and laptops thanks to partnerships with a range of other manufacturers – including Microsoft who have made Token Ring compatible with the Windows Hello log-in for PCs, and keycard access firm HID.
Both Mastercard and Visa are also working with Token, so the ring can be used to make payments or as a transit card on 50 different transport systems around the world, according to the firm.
It also works with Token’s own door and car locking hardware systems, meaning it can be used to open, close and lock the doors of your house and car.
But what about security? Token is unlocked using a fingerprint scanner, which users activate when putting on the ring. Tapping or knocking with the ring twice then activates it and any credentials linked to the device.
Token Ring also contains an optical sensor which means it locks as soon as it’s taken off.
The firm also says any financial information used as part of adding credentials to the ring are never sent to the company’s servers.
The ring, which is available to pre-order in the US, is available in seven sizes and has a two-week battery life, Token says.
It costs $249 (£191), and the firm says it will start shipping in December this year.
