A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional code) designed to be read by smartphones. The code consists of black modules arranged in a square pattern on a white background. The information encoded may be text, a URL, or other data. Created by Toyota subsidiary Denso Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. The QR code was designed to allow its contents to be decoded at high speed. The technology has seen frequent use in Japan and South Korea; the United Kingdom is the seventh-largest national consumer of QR codes. (Excerpt from Wikipedia article: QR code)
