The iPhone X has Face ID, and the Galaxy S9 has Intelligent Scan. While Samsung's Galaxy S9 and Galaxy S9+ still have a fingerprint scanner (located in a better position) they didn't stop there.
To take on Apple's iPhone X Samsung improved it's already pretty impressive Iris Eye Scanning technology. Here's how it works. Samsung's Galaxy S9 uses both the Iris Eye scanning camera on the front, and the facial recognition feature from past Galaxy devices, and blends them both into one feature. Now, your phone will scan your eyes and face, at the same time, and intelligently and securely know it's you and unlock the device. This works in more places, more situations, at night, through glasses and more. It's Samsung's answer to FaceID.
