Tools for Humanity, a company co-founded by OpenAI CEO Sam Altman, is set to deploy thousands of eye scanning devices, dubbed "Orb," across the United States. This initiative represents a substantial growth for the company and its identity verification services. Commencing this week, residents in six American cities will have access to Orb devices at designated locations and partner sites. Having undergone limited testing in the U.S., this technology aims to establish a comprehensive global digital identity system by distinguishing between humans and artificial intelligence.
