Unable to Read AR Cards
Nintendo 3DS
The information in this article can help you when the Nintendo 3DS cameras are not recognizing an AR Card.
Important: You must start AR Games using the Question Mark Card.
What to do
- Check the distance and the angle from the AR Card. The system should be 14 inches away and be held at a 30 degree angle relative to the card.

- Make sure the card is centered on the screen.
- Make sure the game play area is well-lit.
- Make sure a bright light source is not reflecting off the card.
- Make sure the camera lenses are clean.
- Make sure the card is not damaged or dirty.
- Print a new set of cards from support.nintendo.com/ARcards.
