Changes between Initial Version and Version 1 of Ticket #4162, comment 6

initial	v1
38	38	* Adding the QR Code Contents to the Export functionality, to allow it to be integrated with 3rd-party checkin systems (I guess?)
39	39	* Verifying it works with Apple mobile devices
	40
	41	(edit: The Apple device problem could've been due to not having the `muted`, `playsinline` attributes set on the `<video>` preview element - haven't yet confirmed that was the case though)
