QR Codes Explained: Why You See Those Square Barcodes Everywhere
QR codes are plastered on advertisements, billboards, business windows, and products. They appear to be very popular among marketers, although it’s rare to see anyone actually scanning one.
These barcodes can be captured with a smartphone camera — for example, a typical QR code may contain an URL. Scan the QR code with a mobile phone and you’ll be taken to the website the QR code specifies.
Short for “Quick Response code,” QR codes are square barcodes first developed in Japan. Unlike traditional UPC barcodes, which are made up of a number of horizontal lines, a QR code can be captured more quickly and can contain more information.
