    Thread moved. Haven't-a-clue questions don't belong in Advanced Java.

    At least a small explanation on those 'qr codes' or at least a small link would be fine; when I read the thread title my reaction was "yes, finally bit of fine linear algebra"; obviously I was wrong ...

    kind regards,

    I found this.

    But seriously, this really was the first result: zxing - Multi-format 1D/2D barcode image processing library with clients for Android, Java - Google Project Hosting

    For those that don't know but are interested, here is the wiki.

    Basically, a QR code is a 2D barcode which consists of several alignment points and then a bunch of binary data laid out in a 2 dimensional array. You see them as stickers sometimes or on menus, posters, websites, etc...

    There are QR code reader apps for mobile which allow you to scan the code with the camera and then you usually get redirected to a relevant website.

    Ah, thanks for the links; generating qr codes shouldn't be difficult: encode the message and draw little black or white squares according to the encoding, including those three marker squares.

    kind regards,
