An Apple patent document describing the improved Face ID technology on Mac computers is now available online, reports Ferra.

Now retina scanning will also help recognize faces, increasing security and precision at the same time. For instance, retina scanning will help differentiate between twins.

In addition, the patent describes the Touch Bar sensor panel integrated in the Magic Keyboard. On the keyboard, it is placed on the top instead of the first series of the functional buttons.

The date of the launch of the patent technology hasn’t been announced yet.
