Outside of this new feature, you'll also find
the same iris scanning technology that debuted on the Note 7 last year, and also made its way to the Galaxy S8 family earlier this too.
As for rumoured specs, the S9 is expected to feature a Snapdragon 845 chip, 5.7 - inch display, 8 - megapixel front - facing camera with autofocus, 12 - megapixel camera that has the ability to switch between f / 1.5 and f / 2.4 apertures, and
the same iris scanning tech that is found in the current S8.
Not exact matches
Irises do not remain the
same for life, which implies that people might increasingly be able to evade detection when moving between countries that use such
scans, including the UK and UAE
Windows Hello
scans your
iris with the help of onboard
iris scanner and uses the
same to unlock the device.
Then unlock the phone --- by swiping, using the fingerprint scanner, or
scanning your
irises — and you're catapulted into a cleaner colored gradient, with the
same animated star field in the background.
There's also a face recognition feature, which isn't the
same as
iris scanning on the S8 + and Note 8.
Intelligent
Scan allows the device to use both the
iris scanner and facial recognition at the
same time to offer even better security, and it will work well in low light or bright conditions — something that hindered previous scanners on the Galaxy S8 series and Galaxy Note 8.
For
iris scanning, it's basically the
same, but you're holding your eye in front of a camera instead.
That's the
same amount of biometric security as you'll find in the iPhone 8 (where the sensor is below the screen), but one third as many options as you find in the S8, which
scans fingerprints,
irises and faces to unlock.
While
iris scanning is said to be one of the most secure biometric authentication options, the
same can't be said about facial recognition.
