A QR code is made by entering the target web address, phone number, or text into a QR Code generator. Our favorite is the Kaywa generator. This site allows the user to easily choose the content type and the desired size of the code. Along with the actual code image, a permalink and html code are also generated for each code. The Google URL shortener service also generates a QR code, which can be tracked when the code is created while logged into a Google account.
