A variety of Nintendo games feature the option to unlock new items via scanning a QR Code provided by Nintendo. This feature is included in Style Boutique 2 and Style Boutique 2 however no QR Codes have been released for either game. So the QR Code option is unfortunately not usable in the western versions of the game and is only available in Girls Mode 3 in Japan.
There are no plans to release QR Codes for the western versions of the game.
The QR Code option is available from the Add-On Items menu at the game start screen. Even if you attempt to scan in a Girls Mode 3 QR Code into your game, the game will inform you no items are available for download in your region.
