The feature would allow a speed dating even to occur.

As a user already on the platform I would scan the event QR code
then I would see a page with another QR code that is my own with instructions for others to scan it

As a new user I would scan the event QR code
then I would fill a form where I need to fill in email, password, display_name, upload a selfie or photo
then I would see a page with my personal QR code with instructions for others to scan it

In hetero events the women would be the ones who scan or vice-versa but in non-hetero circles either user could scan a personal QR code.

As a signed up user when I scan a personal QR code 
then I see a page with the person's name and photo
with a link to all the users you've scanned

Once the event finishes the profiles you've seen show up with a pass or like button on your phone.

If you had a match... you have to setup a proper fully fleshed out Fresh.Dating profile to start chatting with them

So as you can imagine the point is that these dating events can actually be a growth channel.

Now to further things... some groups organize speed dating events and could just use the app for free so we could outsource some of it to other events.
