It is very easy to generate QR code. http://www.onlineqrcodegenerator.com allows you to create your own code.
We do not have to worry about paying a certain amount of fee because most of these sites are free. Just visit Online QR Code Generator, enter the type of information (data or text) that we want to store in the code. Fill in your personal details such as your Facebook Profile, Name, Company or employer, Phone number, e-mail or other information.
http://www.onlineqrcodegenerator.com will then generate a code that contains our personal information just like what we have typed earlier. We can then print the image and distribute it as we like.
