1. Introduction

This package is the QR Code Decoder Middleware Library. You can use this package to decode QR Code patterns.

This package can be used in retail products.

2. Notes

Use this package only in a Nintendo 3DS environment.

For applications that use QR Code patterns, we recommend that you prepare a means of authenticating the data when decoding, such as encrypting or adding a signature to the data, to confirm whether the data is reliable.

Due to differences in hardware specifications, QR Code patterns that could be recognized on other platforms might not be recognized on this one. In particular, due to the quality of the camera, in some cases small QR Code patterns are not recognized. When using this library, be sure to adequately test whether a QR Code can be recognized before using it.
