QR codes are being used extensively in mobile marketing campaigns overseas, and are starting to make a breakthrough in the US. Quite simply, a QR code is a “matrix” bar code that was developed in Japan. The QR stands for “quick response”, and is being used in marketing for mobile users to take a picture of the code or read the code with the cameras on their phones and trigger an action on their mobile phone. It could be a content download, a message or link to a mobile site.
