how to incorporate a unique barcode for submissions

the basic idea is this.  we use our jotforms for service tickets from our field.  what i was curious is that when the ticket/form is submitted that a unique QR code could be sent emailed that takes you to the completed form pdf??

Though we do not have a built in feature to accomplish this, there is a workaround described in the following thread that will allow for doing this via email but will not include the barcode in PDF output.
