A QR or Quick Response code is a two-dimensional barcode. When you scan such a QR code using a mobile phone camera or a webcam, the QR reader application processes the barcode and either takes you to a Web site, a YouTube video or some other web content. QR codes provide a quick and simple way to point people towards your website or information about your business.
