These distinctive barcodes are generally square and rendered in simple black-and-white blotches. You'll find them on TV shows, in print publications, in subway advertisements...

QR codes are used to reveal more information about a product, service, event or person. Generally, they direct the scanning device to a special URL, video, coupon, event page, email address, or other digital signpost with more details and content.
