Basically, it works like this. Nintendo are offering developer produced Crashmo courses on Crashmo's official Japanese site. It's going to be updated with more in the future. This is the first of such:

By accessing this page on 3DS's browser and downloading the picture, you can then load the picture in Crashmo and play the course. There's no need to take a picture of the QR code with the 3DS's camera.
This works with any QR codes that Crashmo supports that are saved to 3DS's SD card, and, obviously, it's not (afaik) just limited to Nintendo's official Crashmo stages, but any custom-made stages.
