Barcode Scanner is required to read the QR code.
Launch Barcode Scanner and you'll see a red line across the screen. Move the phone forward to make the viewfinder zoom in on the QR code. The light from your computer screen will occasionally make it difficult to read. If that occurs, back up from the screen and then slowly move forward until the QR code comes into focus.
Once the code is read, it will then bring up the app in the browser.
