The profile card screen looks great when someone scans the QR Code, but there is no way for them to save the contact info to their phone for later use.

If you could somehow add the same info that is on the vCard and add a button to allow them to save the vCard to their phone from that it would be amazing.

Also, if you could make it possible for a contact to login and edit that card without needing access to a user account. There is a whole business there for people to sell digital business cards.
