The iris scanner in the Galaxy Note 7 can be used for unlocking the smartphone. It's able to handle glasses and eyepatches, discern high-resolution photos of users' eyes from the actual organs, and works in both light and dark. Early hands-on impressions describe a quick and refined user experience. Additionally, the system is more secure than fingerprint unlocking, as the blood vessel patters in every individual's iris are harder to obtain than fingerprints, which we leave everywhere we touch. It also boasts the lowest measured failure rate.
