QR code is a new and emerging term in Barcode technology.  QR is represented of “Quick Response”, the old barcode only display a sequence of number, this number usually used by the company to generate a unique ID for each item they produce, such as in supermarket the cashier can scan your item faster. But there is limitation in traditional barcode, they only have the capability of 8-10 digits of number, we cannot use that to display an alpha numeric item.

Now days we can use QR Codes to create such as a barcode that contain alpha numeric. For example, we can put “GetSpool” into that Bar-Code, so by simply open your mobile phone and scan those it, we can see the result “GetSpool”. With this kind of capability now we can use a barcode more than before. Blackberry phone uses it, so the user can easily add their friends or family just open the app and scan for a barcode. A blackberry barcode contain of your blackberry pin id (i.e 76582ac) and we can put both number and alphabets in this type of barcode system.

But many time such code help you to save thousands of dollar on your online spending. You might be wondering how could this possible? Don’t worry I will cover it later at post.
