The QR code scanner feature in "Pokemon Sun and Moon" is a hit. The feature allows players use the Nintendo 3DS cameras to scan QR codes in the real world. Players can unlock this feature a little way into the game and it pops up as a new icon in the Pokedex. Every single Pokemon in the game has a unique QR code. Using this feature, players can use the Pokedex to see where a Pokemon spawns in Alola.

This scans the island a player currently is on and then spawns a rare Pokemon that is generally difficult to find in Alola. This way players can catch Pokemon not found in Alola. Only 10 QR code scans are allowed in a day and one attempt to catch the Pokemon.
