Transfering contacts from N900 to Lumia

I don't know if it has been implemented in some resent update, but at the time of doing this video, sending vCard contacts to the Lumias over bluetooth was not supported. But fortunately the Lumias have an integrated QR Code reader, and I had made a QR Code contact exported plugin for the N900. So here it is, a how to on how to transfer contacts from your N900 to your Nokia Lumia device. I knew it would be useful for something :)
