If you look closely, what appears to be an abstract black and white symbol is beginning to show up more and more frequently in magazines, on package labels, movie posters, even on real estate signs. What is this mysterious symbol? It’s a QR code.
QR or “Quick Response” codes are two-dimensional barcodes that carry significantly more information than a typical horizontal barcode. Scanning a QR Code with your smartphone allows you to instantly pull information such as images, websites, or text into your device. Originally developed in 1994 to assist with inventory systems, QR codes are now being used to promote products, events, and services to the smartphone crowd. QR codes are extremely popular in Japan but have only recently been embraced by marketers in the U.S.
