For example, a Fake Check Account entry, QR coded photographs more than the shop.
These black & white images may make no sense to the human eye but the information contained inside the image can be extracted instantly on the desktop or a mobile phone using free decoders.
Example, a fictitious bank account entry details the QR coded image above the store. That information can be easily extracted by passing this image through a QR code decoder application as shown here.
Advantages of QR Codes
Unlike the most well-liked bar code, a QR code collects information in each vertical and horizontal direction and therefore there is more storage capacity per unit area.
Denso Wave, the company that introduced QR Codes to the world, says that QR codes are readable from any direction and that data stored inside QR codes can be restored even if the corresponding image is partially damaged.
How people use QR Codes
For example, some corporations enter their net addresses as a QR code in a print advertisement– people than just click that page with their cell phone cameras and they can visit the advertisers’ website directly without typing anything because the mobile software will decode the image.
How to create QR Code
If you want to create your own QR code, then go to KAWYA – a web QR code image generator. Now to decode these QR images, download a small Java app for desktop or get this reader if you have a Java-enabled mobile phone like Nokia, Sony Ericsson, etc.

For instance, if the short URL is like http://goo.gl/2v21, the QR code for that web address would be http://goo.gl/2v21.qr
