QR Code was developed 1994 by the company DENSO. In contrast to linear bar-codes which encode the information usually in the ratio of the bars or spaces to each other a QR Code is more tolerant with respect to poor printing quality. Each dot in a QR Code symbol represents a bit. In practice up to several hundred bytes are encoded in a single symbol. QR Code is a 2D barcode symbology with very high data density. The Swiss QR Code contains all payment information necessary to trigger payments. In Switzerland, the QR code is used in the numerical part of the QR-bill, which will replace the previous payment slips from June 2020. After decoding the QR Code symbol, the user is forwarded to product related web-sites or marketing campaigns. A user can now scan and decode this QR Code using a mobile phone with a built-in camera and suitable decoder software.
