Sometimes you can find strange squared black and white patterned images in the Internet these days like this one.

These images are called QR Codes (Quick Response) and they contain information such as an URL, binary data, or plain text. Nowadays an application (such as Barcode Scanner for Android) running on a cell phone makes use of the camera of the cell phone to read out its content. I started integrating the QR code to ease the download of the GPX, I collected during my cycles tours. If someone is interested in the same or similar tour, he can download the GPX traces easily by pointing the camera of his cell phone onto the code and the cell will start to download the file automatically. Ideally his cell phone has also a GPS receiver and a application such as TrekBuddy (with maps) installed so that the route can be followed easily. There is no complicated downloading the file to a PC, copying via e.g. Bluetooth etc. necessary anymore.
