What do you know about QR codes?
The acronym QR is derived from the term Quick Response.
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 THEY WORK:
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:
Connect to a web address
Download a MP3
Dial a telephone number
Prompt your email client with a sender address
This can all be done within a matter of milliseconds making the transformation from a users mobile phone to the mobile web instantaneous.
