Sam Altman’s World project has launched in the U.S. It scans users’ irises in exchange for crypto, raising fresh concerns about privacy, biometric data and AI-linked identity systems.

The eyeball-scanning crypto play had originally stayed out of the U.S. market amid a more uncertain regulatory regime.

World is opening six U.S. retail locations for eyeball scans: Austin, Atlanta, Los Angeles, Nashville, Miami and San Francisco. The Orb, a spherical biometric device, scans your face and iris, then creates and stores a unique "IrisCode" for you verifying that you're a human.
