It’s being reported that OpenAI CEO Sam Altman’s eye-scanning venture that’s branded ‘World’ officially makes its U.S. debut today. The device is designed to create a global identity verification system for people that could ideally fight against fraud and bots.

Here’s how it works: You go up to an Orb, a spherical biometric device, as shown in our cover graphic, and it spends about 30 seconds scanning your face and iris, then creates and stores a unique “IrisCode” for you verifying that you’re a human and that you’ve never signed up before. Then you get some of the project’s cryptocurrency, WLD, for free, and you can use your World ID as a sign-in with integrated platforms, which currently include Minecraft, Reddit, Telegram, Shopify and Discord. Starting today, the company is opening six flagship U.S. retail locations where people can sign up to have their eyeball scanned: Austin, Atlanta, Los Angeles, Nashville, Miami and San Francisco.

At an event in San Francisco on Wednesday, the venture announced two high-profile partnerships: Visa will introduce the “World Visa card” this summer, available only to people who have had their irises scanned by World, and the online dating giant Match Group will begin a pilot program testing out World ID and some age verification tools with Tinder in Japan.

World’s “At Last” event in Fort Mason — which featured a performance by singer and rapper Anderson .Paak — included a live demo following a keynote by World Network co-founders Alex Blania and Altman. The demo, which got off to a slightly slow start due to some interference from the stage lights, showed the audience how to pair the Orb to their phones. At one point, the person doing the demo had to take off his glasses so the Orb could see his face a little more clearly.

Although Altman, who is the CEO of OpenAI, spoke at the event on Wednesday, a representative for the company said an integration with OpenAI wasn’t in the works at the moment. For more on this, read the full report by CNBC.
