What is a QR code? A QR code is a two-dimensional code (2D code, matrix code), this means it contains data not only in one dimension (e.g. horizontally from left to right like the barcodes on the products in e.g. your grocery store) but also in a second dimension (vertical and horizontal). The acronym QR is short for “Quick Response”. QR codes are also often called 2D barcodes. The QR code was invented by the automotive industry. Like other codes, the QR code symbol can be captured with imaging devices like a camera and then digitally processed. The error correction capabilities are also used for QR codes with logo (often also called “Design QR code” or simply “QR code with image / icon / logo”). Because of the excellent error correction (they can be read even if up to 30 % of the surface gets destroyed) and the high memory capacity (in comparison with other bar codes), the QR code also gained traction outside the automotive industry.
