Beginning in November, Japanese retailers will begin carrying Nintendo Points cards, which can then be used to buy download software in either the Wii Shop Channel or the forthcoming Nintendo DSi online store.
While Nintendo Points can be redeemed for either Wii Points or Nintendo DSi Points, those Points can not be shared between the Wii and Nintendo DSi's online shops. As with the existing Wii Points setup, 100 Points are equivalent to $1.
Only accessible from the new Nintendo DSi, the DSi's online store is expected to arrive alongside the enhanced $190 handheld on November 1 in Japan. A North American release of the DSi and its bigger screens, slimmer profile and increased internal memory is not expected before April 2009.
