What is QR Code and how to generate it?
Of late it has been seen that the mumbo-jumbo i-phone users are preferring   to read the latest news updates/ articles on the move. Yes, it is indeed a   telepathic transformation of hardcoded contents at your finger tips..! 
The QR Code: The process of reading information has been made even   simpler when you see a QR Code in a magazine. Just scan and read it, that simple   it is.
QR Code abbreviated form of Quick Response Code is a type of matrix barcode   initially designed and confined for the automotive industry. 
Structure of a QR code, highlighting functional   elements
It was designed to allow its contents to be decoded at stunning high speed.
The QR code is detected as a 2-dimensional digital image by a semiconductor image sensor and is then digitally analyzed by a programmed processor. The processor locates the three distinctive squares at the corners of the image, and normalizes image size, orientation, and angle of viewing, with the aid of a smaller square near the fourth corner. The small dots are then converted to binary numbers and validity checked with an error-correcting code.
To read QR code, you need a QR code scanner app on your smartphone. Lots of   QR Code scanner is already available under Android store. Google Goggles and   NeoReader are free apps that work great on Android, Windows Phone and iOS   devices. I'm using ixMAT Scanner with my Samsung Galaxy Note. You can scan   either Barcode or QR Code from any store and search and benchmark the product   price online.
