    QR Codes are those square barcodes that you often see on advertisements, billboards, business windows, and products. Unlike ordinary barcodes that just contain vertical stripes, QR Codes contain black squares arranged in a square grid on a white background. QR Codes are designed to be quickly and easily read by cameras, smartphones, or dedicated QR Code scanners.
