QR Codes are common in Japan, where they are currently the most popular type of two dimensional codes. Most current Japanese mobile phones can read this code with their camera. 
Although initially used for tracking parts in vehicle manufacturing, QR Codes are now used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile phone users (known as mobile tagging). QR Codes storing addresses and URLs may appear in magazines, on signs, buses, business cards, or just about any object that users might need information about. 
Users with a camera phone equipped with the correct reader app can scan the image of the QR Code causing the phone's browser to launch and redirect to the programmed URL. This act of linking from physical world objects is known as a hardlink or physical world hyperlinks. 
Today QR Barcodes are being used in marketing campaigns for the end user to scan & be led to specific campaigns, websites, songs, coupons and much more. 
The key to producing the barcode is the quality of imprint upon the item. 
It is key to a clean imprint. Size is also an issue, depending on the Barcode size, you may be limited to the actual imprint size to be scanned.
