Can you please tell me how QR code is actually created and how they are tracked. Generated codes are deposited in a DB.
I am really confused how the QR Code Reader application works. If I create a site where the user can generate QR code, each generated QR code will be saved in my site DB. Again, do I have to write an application too? An application that will read QR code images from an image and work accordingly or will a QR code reader app work?

QR code is a type of two-dimensional barcode Is used to store small quantities of text or data (see Wikipedia).
Implementation in today's mobile phone platforms such as Android can use the contents of a QR code, because different sizes and error correction levels of the QR barcode are present. URL to be opened in the phone's web browser (Apple iPhone should be able to read QR codes using free semicond software.) Therefore, you can use these barcodes as a web site log analyzer using such tools Can track.
Other data formats that mobile should be used in the phone include vCard, which is used to store a person's contact information (see Wikipedia). Unlike the URLs, they can not be easily used (i.e., if the user dials the phone number instead of opening the URL inside). Although the bare URL is commonly used with the QR code, vCard has a URL field.
If you want to generate a QR code from your web site, then you can call Google Charts (Adam Stroghan) or if you want to do this on your own server, then popular programming languages (eg. , For PHP, or Java) can use one of the many libraries present. You must give a valid URL or vCard in the form of text to encode in order of a scanned QR code by a mobile phone. The industrial applications which are different in encoded.
Mostly, you will not store QR code images in the database themselves. Instead, you will store the other text inside the URL or barcode, so that when necessary, see barcode scan or information needed to reproduce the barcode as needed.
