QR-Codes are two dimensional barcode (datamatrix) that is designed to have it's contents decoded at a high speed.
The acronym QR is derived from the term Quick Response. The company Denso Wave originally spawned the term QR as the creator intended that such barcodes and their contents were to be decoded at high speed electronically.
QR-Codes originated within the technology hungry country of Japan and have merely only recently began to become popular within the Middle East and Europe.
Barcodes that you see on any commercial product are extremely beneficial as their reading speed, supreme accuracy and their functionality are key.
As barcodes reached their peak and began getting used worldwide, the need for more data and characters types to be stored was inevitable.
Developers began tying to expand on the current amount of bars within the barcode and how their positioning to allow further data capacities. The need for smaller barcodes also was another defining factor in their development.
Such developments failed as reading and printing implications caused more problems than solutions. The 2D barcode was then born.

Take a mobile phone such as the iPhone; nearly ever mobile phone has a digital camera in today's world. The camera, along with decoding software can be used to capture a picture of the QR-Code of which the QR-Code software decoder and then transform the data held with the QR-Code to a meaningful action for the mobile phone:

This can all be done within a matter of milliseconds making the transformation from a user's mobile phones browser to the mobile web instantaneous.
