3DS owners will now be able to StreetPass users using Nintendo Zone hot spots across the UK.
The initiative is part of Nintendo's greater drive to promote the social features of the 3DS console.
Players will not only have access to the Nintendo eShop, but will be able to share screenshots and in-game content with friends via the StreetPass service.
The service will provide console owners with greater opportunities to connect with other 3DS users through StreetPass encounters.
Nintendo is aiming the feature at users who many not be able to interact with other players within their local area.
The firm hopes the addition of the StreetPass relay will increase the appeal of sharing features within 3DS games.
The StreetPass Relay functions by allowing players to connect with other whenever they're connected to one of the UK's 25,000 Nintendo Zones.
Not only will players be able to interact with other StreetPass users, but their information will be passed on to the next 3DS owner that visits their location.
The changes are set to be implemented within an upcoming 3DS update.
