Random Culture bothers to explain QR Codes and I, for one, am thankful.
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.
Give the NeoReader a try 🙂
It is able to read and decipher all common non-proprietary 2D codes (Data Matrix, QR, Aztec, Maxi) as well as URL embedded 2D codes and all 1D UPC/EAN/Code 128 open source codes. The NeoReader supports direct and indirect code linking, which guarantees maximum interoperability with already existing platforms like 2D Data Matrix Semacodes, and Japanese QR links. This allows the user to click on a variety of codes with a single application installed on their mobile device.
