QR codes (Quick Response) are a type of 2-dimensional bar code which is currently very popular. Originally designed for industrial use in tracking items as they move around a warehouse or factory, they are currently mainly used to provide hyperlinks in ads, articles, and signs which somebody with an appropriate reader (such as apps for a smartphone) can use to retrieve what is generally a URL linking into the Web, though other kinds of content can also be stored.
