QR Code (Quick Response Code) is a type of two-dimensional bar code that consists of square black modules on a white background. A QR Code is made of small black squares and rectangles that are arranged in a square pattern on a white background that codes for text, URL or other information. QR code formats are now standardised under ANSI as well as AIMI in 1997 and to ISO/IEC standards in 2000. (Refer to the Barcode)
