The QR Code is a so-called 2D barcode, which has been developed by the Japanese company Denso Wave in 1994. QR means Quick Response.

The QR Code is built on a square matrix with black and white pixels which represent the binary coded data. Using special marks in three corners, the alignment of the QR Code can be recognized. The data content of a QR Code is protected by a special code which helps restoring up to 30% of damaged data, depending on the error correction level.

Upozornění: The current implementation of QR Code in Barcody supports error correction level L, which means that up to 7% of damaged data can be restored.
