You can use Nintendo Points to buy WiiWare or Nintendo DSiWare games, Virtual Console games or add-on content for certain titles. Nintendo Points can be added to your Wii Shop Channel or Nintendo DSi Shop accounts by entering the code found on Nintendo Points Cards. When Nintendo Points are added to your Wii Shop Channel account, they will become Wii Points. Likewise, redeeming a Nintendo Points Card in the Nintendo DSi Shop will turn Nintendo Points into Nintendo DSi Points.
Nintendo Points Cards can be bought from retailers, or purchased online with a credit card in the form of Wii Points or Nintendo DSi Points via the Wii Shop Channel or Nintendo DSi Shop. Nintendo Points Cards can also be purchased from the Nintendo Points Card Shop with Stars from your Club Nintendo account.
