To verify that they’re not a bot or an AI agent, users have to physically visit one of World’s orbs in person. According to World, the orb “takes pictures of your face and eyes, then encrypts and stores them on your phone so that only you control them by default.” After completing the facial scan, users can connect their World ID to eligible apps like Tinder, which gives orb-verified users a “verified human badge” on their profile. Tinder users can also verify their profile with a photo or a government ID, but the offer for five free boosts is currently only for those who verify with World ID, and is only available for a limited time.

World is also launching a World ID app, distinct from the World super app it announced last year. The World ID app is specifically for managing “proof of human” verification with the various apps and services that currently accept it, which doesn’t just include Tinder — World is also integrating its ID service into Zoom and Docusign.
