StreetPass

StreetPass is a unique communication feature for Nintendo 3DS and Nintendo 2DS systems. When two compatible systems are in close proximity and have StreetPass enabled, they can exchange small amounts of data wirelessly without user intervention, as long as both devices are in sleep mode. This exchange occurs automatically when the systems detect each other.

The data exchanged can vary depending on the game or application. For instance, in the built-in StreetPass Mii Plaza, users can exchange Mii characters. These Miis can then participate in mini-games, such as "Find Mii" or "Puzzle Swap," using the Mii data received from others. Other games might allow players to share in-game items, unlock special content, or contribute to a collective goal.

StreetPass functionality requires the Nintendo 3DS system to be in sleep mode, with wireless communication and StreetPass features turned on. The range of the StreetPass signal is typically around 30 feet. Users can encounter other StreetPass-enabled systems in various public places like train stations, airports, or even during Nintendo events. The feature aimed to foster a sense of community and provide ongoing engagement with games even when not actively playing. While the Nintendo 3DS family of systems is no longer in production, StreetPass played a significant role in the system's user experience and was a distinctive selling point.
