QR Code reveals brand's website!

Whenever I go to supermarkets I find a hand held device being used for billing the purchased items by reading the bar codes present on them. Recently, I received a parcel by post that had a black square placed on its package. On its side, it was printed: ' ... point your phone's QR code reader on this marker.' What is this QR Code? And what for it is used? It is the Quick Response Code, and it is of matrix bar code type. It has large data storage capacity and faster readability than the usual bar code (UPC). It is produced by QR code generator and is readable by an image sensor (QR code reader). This QR code reveals the website of the brand of the item. So, it it is used as an advertising strategy to boost the sales of the company's products. As its code reader applications are commonly available in all the consumers' smart phones, it has become more consumer friendly.
