Motiv's fitness ring transforms into a biometric safety device



Motiv adds heart rate awareness features to its smart ring that allow payments to be made later in the year, the company said today at CES. The ring has always measured your heart rate to track your exercise and activity. Now the company wants to measure the heart accurately enough to read it like a fingerprint and verify your identity. Once your identity has been verified, the ring can communicate with terminals to authorize payments. Motive intends to add the new features in the second half of 2019 via a software update.

The device is based on the theory that every heart emits unique signals in its heart rate. Motive intends to use electrocardiography (ECG) to verify your identity. The ring is already FIDO certified to log in to your online accounts via the WebAuthn standard, and as a two-factor authentication device. However, this currently requires certain gestures while wearing the ring. In the past, the company also considered using your approach as an authentication method called "Walk ID". However, this heart rate tracking could be a much more convenient safety method. The biggest question will be how accurate the heart rate tracking is and whether the system can be dropped by exercise or other heart irregularities.
