Have you ever seen a picture like the above and wondered what is it about? Well, the unique picture is a QR code that is used to easily track products. Named a quick response code, it was previously used for vehicle and parts tracking in the automotive industry. Now it is being used in other industries, as a fast tool to present some information.
Before dedicated cameras were used to scan the code and extract the information, whereas now on 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 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 to their news portal or some multimedia links that cannot be shown on paper. Some advertisements in the dailies now even have this code to present the video ad on 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 URLs, QR codes can be used in virtual stores, code payments, and some authentication.
