Do you have an app that works with your forms so that we can scan QR bar codes

Do you have an app that works with your forms so that we can scan QR/bar codes to check registrants in at events?  We don't want to use the spreadsheet manual method due to the size of our event. 

You can use the QR Code widget on your form.
