Wearables as biometric social IDs

Fitness wearables are being used not just to track health but to authenticate real persons on social platforms by exposing a live or recorded biometric signal. Framing health metrics as a 'verified heartbeat' turns intimate physiological data into an identity credential that platforms can require or market as an anti‑bot guarantee. — This matters because normalizing biometric identity through consumer wearables reshapes privacy norms, platform gatekeeping and the boundary between health data and civic identity.
