A December system update for the Nintendo 3DS portable system will allow users to combine their Nintendo eShop account balance for both Nintendo 3DS and Wii U.

Users can register their Nintendo Network ID for Wii U on their Nintendo 3DS systems and combine Nintendo eShop account balances. This will enable them to purchase Wii U software using the remaining balance on their Nintendo 3DS eShop accounts, and vice versa. Nintendo 3DS owners who do not own a Wii U system can also create their own Nintendo Network ID for the first time.

This system update will also mark the beginning of Miiverse support on Nintendo 3DS.
