    ...With my iPhone.
    Not sure if someone's posted this, but the result was... Interesting.

    CODE?,$FØk÷(BrM|ÃÐ}?ã
    °ÍËÏ?Ï?ûkÐ&?ðmj&áØ°@:lÝiÍ?$Ê7dH?ÏÎ(b
    oÛI£êG|8SÂG0?h?PF2

    By interesting I mean I have no clue what that means. Anyone think they can try this an 'decode' it?

    You mean, you've scanned a QR code containing a Mii ?
    If that's the case, then what you see are the parameters of Mii (head shape, hair color, eyes distance, and everything else) encoded in binary - that is, over 8 bits.

    Open an .EXE file in Notepad, it won't make any sense to you either.

    1st[​IMG][​IMG]
    2nd[​IMG][​IMG]
    3rd[​IMG][​IMG]

    Looks like the data for the qr codes is encrypted.
    The 2nd qr is exactly the same as the 1st qr except the name is changed from a to b.
    The 3rd qr has just one facial feature changed from the 1st qr. The name is the same.

    In each case the dots are completely scrambled. I don't know why the N wanted to encrypt this harmless data, but they did, lol.

    What would happen if you scanned 2 codes, then used 2 halves of the code to make a QR code.

    Example:
    CODE‘,$FØk÷(BrM|ÃÐ}“ã
    °ÍËÏ“Ï™ûkÐ&‹ðmj&áØ°@:lÝiÍŸ$Ê7dH…ÏÎ(b
    oÛI£êG|8SÂG0˜h–PF2

    Then you take another code and replace the 3rd line.
    CODEoÛI£êG|8SÂG0˜h–PF2

    I don't have another code. And what would happen if you try to scan the code Pong posted? I assume nothing, but what if you put the 'Mii' logo in the middle?

    I have no form of hacking theory, I just find this interesting. [​IMG]

    Nothing, it's the incorrect dot resolution. Nintendo qr codes are 57X57 dots, Pong's is 45X45 dots.

    Also, if you observe post #6 there is strong evidence the qr data the 3DS reads is encrypted. This means that any qr code processed* from a non-3ds device will be unreadable to the 3ds.

    *unless it is directly copied from a 3ds qr code, of course

    I tried similar things with my QR codes and came to the same result, i believe them to be encrypted.

    Even minor things such as changing the eye colour of my mii would result in a completely different QR code.

    I was disappointed, i was hoping to work out how to manipulate the QR codes and try things that shouldn't normally happen (e.g there are six types of eye colour, what happens if i set the QR code to choose a seventh colour? etc. - most likely wouldn't have worked but fun to try)

    By meh, nevermind. Maybe someone smarter than I will find a way to decode the codes/generate our own on our computers.

    What you have to do is to compare the binary information stored in both barcodes (e.g. using a hex editor), not compare them visually.
    But yeah, they might be encrypted anyway.
