What are QR codes and how can they help your business? Keep reading to find out.
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.
QR Codes 101
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.
Bar codes are linear one-dimensional codes and can only hold up to 20 numerical digits, whereas QR codes are two-dimensional (2D) matrix barcodes that can hold thousands of alphanumeric characters of information. Their ability to hold more information and their ease of use makes them practical for small businesses.
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.
