EVA Networking · contacts by QR code
At the coffee break, two attendees connect
One shows the QR code on their badge, the other scans it, and nothing happens until the owner says yes. No more business cards, and nobody’s details given away.
A unique QR code per attendee, built into the event badge.
Explicit acceptance: each person decides who walks away with their contact details.
EVA suggests who to connect with based on shared interests.

The photos attendees send to the same chat get projected onto the event wall, next to the posts carrying the official hashtag. And anyone watching from outside wishes they were inside.
A live wall: attendee content on the screens, in real time.
The official hashtag built in: the event amplifies itself on social.
Automatic moderation before anything is projected: you decide what makes it to the screen.

The keynote ends and the ratings are already coming in
Before the room empties, EVA asks and attendees answer, because they are one tap away, with their mobile in their hand. Anything urgent does not wait for the debrief.
Ratings while it is fresh, session by session: the answer arrives while the room is emptying.
Automatic alerts to the organisers when something urgent shows up in the conversations.
