Quick Response codes (QR codes) and other two-dimensional codes are expected to achieve widespread use this year – and for good reason. Consumers want immediate access to what’s relevant and QR codes are being used to make that possible.
If you’re not yet familiar with QR codes, they’re similar to the barcodes used by retailers to track inventory and price products at the point of sale. 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.
