It’s still not clear what an eye scanner could be for, but DigiTimes suggests that eye scanners on mobile devices could be used for “biometric recognition,” like the iPhone’s fingerprint sensor. That means it could use your iris to unlock your phone and any functions that need a password.
DigiTimes’ report is a little sketchy, as there’s no indication of where the information came from apart from DigiTimes’ own “industry sources.” The report does note that Chinese tech companies have been developing eye-scanning, but that doesn’t necessarily mean the iPhone in 2018 will have an eye scanner.
However, it’s not too far from reality, as it’s also rumored that the Samsung Galaxy Note 7 will have an eye scanner, with rumors suggesting it would also be used for unlocking the device. If the Note 7 has an eye scanner, so could the iPhone.
Apart from the eye scanner, we haven’t heard any other rumors about the 2018 iPhone — it is, after all, at least two years away from release. Normally we’d presume it would be called the iPhone 8s, but recent rumors suggesting Apple will shake up the iPhone’s release cycle puts that nomenclature tradition into question.
Remember, leaks and rumors about any unreleased iPhone don’t confirm anything. We’ll only know for sure whether or not these rumors are true when Apple releases these iPhones.
