Wii U's unique controller will use NFC technology to allow users to read and write data (in a similar way to how the Skylanders figures work with the 'Portal Of Power') and also pay for things with compatible bank and credit cards.
"By installing this functionality, it will become possible to create cards and figurines that can electronically read and write data via noncontact NFC and to expand the new play format in the video game world," said Iwata.
"Adoption of this functionality will enable various other possibilities such as using it as a means of making micropayments."
As part of a financial briefing released this morning which also confirmed a new Mario 3DS game is in the works, Nintendo president Satoru Iwata also confirmed that the company will be focusing its efforts on building Nintendo Network - the online platform which will serve 3DS and Wii U.
"Competitions and communication among users, as well as the sales of digital content" - essentially DLC - will be part of the package, says Iwata.
Iwata also re-iterated that the Wii U release date will come by the end of the year.
