AR Card

AR Cards are plastic cards that the Nintendo 3DS uses as position trackers for some augmented reality experiences, such as AR Games. When the image of an AR Card is in clear view of the console's outer cameras, it can cause some in-game effect. Only the image on an AR Card is important, though the size and material of replacement AR Cards can impact readability.

Six AR Cards are bundled with the Nintendo 3DS: the "?", Mario, Link, Kirby, Samus, and Pikmin Cards, respectively labeled A-1 through A-6. The "?" Card has a ? Block symbol and is used to start AR Games. Games such as Nintendogs + Cats have Super Mario-related content accessible by scanning the Mario Card. Some games, like Photos with Mario, use additional sets of AR Cards.
