Nintendo Points are a currency that Nintendo uses for its Wii and Nintendo DSi systems through the Wii Shop Channel and Nintendo DSi Shop respectively.
Nintendo Points were originally named Wii Points, though with the introduction of the Nintendo DSi and its own download service, they were renamed and new Nintendo Points Cards with new values were distributed. Once purchased, Nintendo Points must be converted into either Wii Points or Nintendo DSi Points before they can be used, locking the points for use on one platform only.
