QR Codes ("Quick Reference" Codes) are essentially 2-dimensional barcodes. They can contain hundreds of times more data than conventional 1-dimensional barcodes [1]. Initially created for use in the shipping industry, they are gaining popularity for marketing to people with smart-phones. Many consumer-oriented QR codes point users to a website address, although other types of data storage are possible. Generally, users scan the QR Code with a scanning device (for example, the camera on a smart phone), and they are automatically directed to a website or the application specialized to handle the code's data. The idea is to allow users to avoid the hassle of remembering or manually reproducing long, precise strings of data.
