StreetPass

StreetPass is a feature present in every Nintendo 3DS system that allows users to exchange data on games that the two own. It is on regardless of whether the 3DS is in sleep mode or not, and is activated when another 3DS user walks within the console's range. With it, players can acquire new features in games that they own (even if the game's card is not presently in the 3DS card slot) and obtain the Miis of 3DS users that walk past them. If one wishes, they can turn the feature off completely or assign the games that they want it to work with. Several games have made use of this function in unique ways.
