What is a QR Code?
QR-Codes are two dimensional barcode (datamatrix) that is designed to have its contents decoded at a high speed.
Static QR codes, the most common type, are used to disseminate information to the general public. They are often displayed in advertising materials in the environment (such as billboards and posters), on television and in newspapers and magazines. The code’s creator can track information about the number of times a code was scanned and its associated action taken, along with the times of scans and the operating system of the devices that scanned it.
Where did QR Codes come from?
History: QR-Codes originated within the technology hungry country of Japan, and have 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 character types to be stored was inevitable.
Developers began tying to expand on the current amount of bars within the barcode and how their positioning resides to allow further data capacities. The need for smaller barcodes also was another defining factor in QR-Codes development.
Such developments failed as reading and printing implications caused more problems than solutions. The 2D barcode was then born.
How do I use a QR Code?
Take a mobile phone such as the iPhone; nearly ever mobile phone has a digital camera in todays 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 can 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 users mobile phone to the mobile web instantaneous.
