Invite by QR code

Does anybody think that it could be useful if D* generated a QR code image below the text field with the invite link?

This could be useful particularly in the mobile UI.

I made a QR for my invite link and printed about 50 of those QR codes on a single piece of paper - I can now just hand them out to people when I meet them.

Seems a logical and simple way of spreading the word about D* and getting new members onto pods.
