“The ring’s eponymous developer, a FIDO Alliance member, has partnered with some big names to ensure compatibility.”
A new wearable device is aimed at enabling a kind of continuous biometric authentication paired with wireless technology allowing users to do things like make payments and unlock doors with a wave of the hand.
It’s called Token, and it’s a relatively thick, plain-looking ring. It features a fingerprint sensor on the inside; once a user scans her finger and slips it on, she’ll be able to use the device for authentication at any time. An optical sensor detects when the ring is removed, and then another fingerprint scan will be required the next time the user wants to put it on and use it.
The ring’s eponymous developer, a FIDO Alliance member, has partnered with some big names to ensure compatibility. Mastercard has enabled Masterpass digital payment functionality for the device so that it can be used to make purchases, and Visa and Microsoft are said to be partners as well. HID is also supporting the device, allowing it to be used to open doors locked with HID’s contactless smart card readers.
The device starts at $249, with additional features available for purchase that can enable it to be used with locking and car ignition systems. Black and rose gold models are also available for an extra $50.
