Its simple really. You run the app and youre taken to your native scanner -- there are no screens besides the scanner! Scan the QR code. The text contained in the QR code is pushed to the clipboard. Finally youre taken back to the home screen with your text ready to be pasted into the app of your choice. ... Like I said, simple! :D This is great if youre on a PC or Mac and want to type something really fast. I would recommend going to a site like www.qr-code-generator.com, select the text tab, type away, then generate your QR code. If you have any questions or comments please feel free to let me know!
