Wii U Controller has new Communication Functionality
NFC, short for Near Field Communication, is a communication standard which allows for wireless distribution of information. Iwata described the uses of NFC to investors in this way:
“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. Adoption of this functionality will enable various other possibilities such as using it as a means of making micropayments.”
Nobody knows how Nintendo plans to make use of the Wii U controller’s NFC abilities. In addition to this, communicating with its own system, the tablet could conceivably relay information to other Wii U systems or controllers.
