Tools for Humanity, the company behind World ID, a digital identity system that verifies whether someone is a unique human online using biometric data without sharing personal details, announced that it is expanding its iris scan-based World ID system to Tinder, Zoom, and DocuSign.
The rollout marks a significant step in pushing biometric identity tools into mainstream online services. According to World, the goal is to allow users to prove they are real humans—without sharing personal details—positioning the technology as a foundational layer for the internet.
In a company blog post, World said Tinder will expand its World ID integration to the United States following a pilot in Japan. Verified users will receive a profile badge along with five free Boosts. Zoom is integrating a feature called Deep Face into meetings, using a three-way match between a previously verified image, a real-time selfie and a live video feed to confirm a participant is human. DocuSign will use World ID to verify that a real person is authorizing document signatures.
The company said 18 million people across 160 countries have already verified their identity using its Orb devices.
World’s system relies on a physical device known as the Orb, which scans a user’s iris to generate a unique cryptographic identifier stored on their smartphone. The company says it does not collect names, addresses or other personal details, and that partner platforms receive only a cryptographic attestation confirming a user is a unique human.
Other identity verification providers are taking different approaches.
Persona, for example, verifies attributes such as age or “humanness” by matching government-issued IDs with live selfies, without requiring specialized biometric hardware. According to the company, it does not sell personal data or use it for AI or model training.
Major platforms are increasingly exploring these tools.
Reddit CEO Steve Huffman said the company plans to rely on third-party verification services to confirm accounts are operated by real people without requiring users to disclose their real-world identities. Meanwhile, X states in its verification policy that it uses Persona for ID checks and deletes sensitive data such as ID images and selfies after 30 days. Persona also launched a product called Relay in April, designed to separate identity verification from user activity so that who someone is cannot be directly linked to what they do online.
World, formerly known as Worldcoin, was co-founded in 2019 by Sam Altman and Alex Blania. Tools for Humanity is the primary company behind the project. The initiative has faced regulatory scrutiny in several countries, including investigations into potential data protection violations. Despite this, the company says it plans to deploy more than 7,000 Orb devices across the United States and is developing an Orb Mini, a portable version of its verification hardware.
