One of the big talking points surrounding the iPhone X, apart from its price, was the removal of a physical home button and Touch ID, which was replaced by a new Face ID system. The jury is still out on facial recognition software on mobile phones, with the likes of the Galaxy S8 still being duped now and then by printed images of faces rather than the genuine article.

To that end, Mashable recently tried to put the iPhone X's Face ID software to the test in a video, using two sets of twins to 'fool' the system.

The first twin registered their facial features onto the iPhone X, which involves holding the front facing camera at one's self, then moving your head in a circle to ensure it 'captures' all the necessary angles.

Before the big reveal, each set of twins discuss their past experiences with facial recognition software, in some instances even bypassing the other twin's face unlock mechanism. Following their remarks, the second twin (the one that did not register their face) tried to unlock the iPhone X by staring at the screen.

To see whether it worked, watch the video below.
