What Is A QR Code?
The QR Code is a two-dimensional version of the barcode, known from product packaging in the supermarket. Originally developed for process optimization in the logistics of the automotive industry, the QR Code has found its way into mobile marketing with the widespread adoption of smartphones. "QR" stands for "Quick Response", which refers to the instant access to the information hidden in the Code. QR Codes are gaining popularity because the technology is "open source", i.e. available for everyone. Significant advantages of QR Codes over conventional barcodes are larger data capacity and high fault tolerance. The black and white checkered pixel patterns appear at first glance to be a small crossword puzzle and seem to be composed at random. But if you look closely, certain structures can be identified. For the scanner to recognize a QR Code as such, the Code must always be square. A number of additional elements ensure that the information is read correctly.
