Have you ever seen any picture like above and wondered what is it about? Well the picture is a QR code which is used to easily track products. Named as quick response code, it was previously used for vehicle and parts tracking in automotive industry. Now it is being used in other industry, as a fast tool to present some information.
Before dedicated cameras were used to scan the code and extract the information, whereas now in the consumer end, smartphones are used to scan the code and give the information in some useful form like a URL for a website. Hence it is used in advertising of a product, where the product’s website can be easily accessed without manually entering the URL.
We can even see the codes in our daily newspaper for the link of their news portal or some multimedia links that cannot be shown in paper. Some advertisement in the dailies now even have this code to present you the video ad in YouTube or their Facebook fan page.
Most of the smartphones available today can easily generate and read the QR codes, otherwise you can even use some applications to make or read those codes. Besides URL, QR codes can be used in virtual stores, code payments and some authentication.
