If you’re not yet familiar with Quick Response codes (QR codes), they’re similar to the barcodes used by retailers to track inventory. The key difference between the two is the amount of data they can hold or share. When you scan or read a QR code with your iPhone, Android or other camera-enabled Smartphone, you can link to digital content on the web; activate a number of phone functions including email, IM and SMS; and connect the mobile device to a web browser. The ability of QR codes to connect people with each other and to multimedia digital content is very useful for businesses and consumers alike. Give it a try!
