Animal Crossing New Leaf is a game for 3DS, and during the play, if you keep on contacting Able Sisters, you will become able to design your own cloth, hat, flag, etc, and also enables sharing with your friends by using QR code.
I have created Android app for reading / writing this QR code, with design tool so you can design using your android device. I will leave data structure for QR code I’ve analyzed during development, for somebody who might want.
Below is movie for my app for reference.
Data is encoded to QR code in binary format, with multiple QRs for some designs, which is a rare type of QR code usage.
