The first generation of QR Codes appears as a two-dimensional barcode that manifests as a square consisting of black and white dots. Like all barcodes, the QR Code is essentially a code that contains information and when scanned by an appropriate QR Code scanner that is available for all Smartphones, they redirect the scanner to a certain destination, providing their creators with a wide range of possibilities for their use. Although most QR Codes are used to redirect their scanners to a set destination such as a URL, a Google map location, a YouTube video or a Facebook profile page, they can also be used for many other functions such as transmitting vCards, calling via Skype and sharing statuses via social networks like LinkedIn, Facebook and Twitter.
