My recommendation now for making a QR code for sharing Google Forms is to use QR Droid Zapper. QR Droid Zapper lets you make a QR code for sharing all kinds of things from webpages to contact information to files to Google Forms. It's an easy tool to use and doesn't require any kind of registration in order to use it. Watch my new video to see how easy it is to use QR Droid to create a QR code for a Google Form.
