How does check-in work at the door?
Every confirmed attendee gets a ticket with a QR code, which they can add to Apple Wallet or Google Wallet. At the door, you or your co-organisers scan it with the phone's camera: the arrival is recorded straight away and a second scan is flagged. You can also find attendees by name in the list. No equipment to rent.
What is the networking card?
A digital business card for networking. If you turn it on, every confirmed attendee can create their card: name, job title, company, LinkedIn and, if they wish, email, phone number and photo. Two attendees scan each other's QR codes and each gets the other's card, ready to add to their phone contacts in one tap. Exchanges are open from 2 hours before the start until 7 days after. If you turn the option on, everyone receives an SMS recap of the people they met the next morning.
Can the organiser see who met whom?
No. You only see overall statistics: cards activated, number of exchanges, activity hour by hour. Each attendee chooses what they share and can deactivate their card at any time.
