Iris biometrics prove uniquely reliable for identity verification
Iris patterns are astronomically unique, making them ideal for biometric ID. Unlike facial recognition, irises never change and can be scanned from up to three feet. Tools for Humanity announced World ID for Zoom, using its Orb scanner to verify participants by matching a selfie to a prior iris scan, aiming to combat deep‑fake scams. Only 18 million people have used the Orb so far, but the technology could become essential as online bots increase.
