Once you have downloaded the QR code reader to your phone, point the phone to the QR code. Some QR code readers will require you to snap a picture and others will only require you to have the QR code registered steadily on the screen. Make sure that you fit the whole code onto the scanner bars on your mobile screen. Sometimes you may need a few attempts to get it right. Less than 30 seconds after the scanning, you will be brought to the web page or URL link. If its a V card it will offer to download it onto your address book.
