Apple has filed and received a patent for the iPad Smart Cover which will have multiple uses while enhancing the popular tablet's existing features.
The iPad smart cover will have the capacity to extend the iPad's display through text, functioning as an input device. Apple's design illustrations show that the cover has four connection points instead of the standard three, which implies that the cover could be used for purposes other than protection, but also as a surface on which one can type.
The designs feature solar panels as well as the cover itself that is used as a touch panel. The surface of the cover appears to have notes on it which may mean that it can function as a writing pad. The iPad Smart Cover may also include a live drawing pad which would be compatible with an Apple Pencil writing tool.
