Dynamic QR Code URL Saver

Idea is great because so many dead liks are the and some qr codes will e printed as well.

I red that pretty links offer this but can't find this option there.
I would love to have an export there and best case directly from post editor ;)

I would like to believe the best ;)

Generates a dynamic QR-Code, which can be saved and edited later, even if the QR Code was printed. Very easy to install and use. Share smartly!
