Structured data


Add a one-line explanation of what this file represents

The unmodified QR code is shown in blue, superimposed over the artistically modified version. The letters of the Wikipedia logo have been carefully placed so that they mostly line up with the blocks of the QR code. This tends to reduce the number of scan errors caused by the modifications.

The area occupied by the logo is unused space that does not actually encode any useful information. The URL is stored in the space above the logo, while the space below contains error-correcting codes. This QR code is encoded with the lowest available level of error correction.


English: Illustrates why the artistically enhanced File:Extreme QR code to Wikipedia mobile page.png is still scannable.
