Worldcoin will expand its operations to sign up more users globally and aims to allow other organisations to use its iris-scanning and identity-verifying technology, a senior manager for the company behind the project told Reuters. Co-founded by OpenAI CEO Sam Altman, Worldcoin launched last week, requiring users to give their iris scans in exchange for a digital ID and, in some countries, free cryptocurrency as part of plans to create a "identity and financial network". In sign-up sites around the world, people have been getting their faces scanned by a shiny spherical "orb", shrugging off privacy campaigners' concerns that the biometric data could be misused.
