Pokémon Sun and Moon includes QR code feature
QR codes with the handheld's camera. The QR scanner function will give players a very different method of registering Pokémon in their Pokédexes. The games' website details how the new feature will work: QR codes contain information about Pokémon which, when scanned, then gets added to the Pokédex. Trainers still have their work cut out for them, though — if the QR code scanned belongs to a Pokémon they haven't yet caught, they'll be provided with the monster's habitat so that they can scout it out.
