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.
I feel like I am missing something about how this works.
Take this use case “ Companies could pay Worldcoin to use its digital identity system, for example if a coffee shop wants to give everyone one free coffee, then Worldcoin’s technology could be used to ensure that people do not claim more than one coffee without the shop needing to gather personal data, Macieira said.”
What is stopping someone from showing up with 2 IDs and claiming 2 coffees. I dont know how you prove that the person showing up with a coin is the person who was physically scanned. Much less how you prove the person today was the person who was scanned 40 years ago.
