How NFC Tap Works
Badge-to-Badge Tap
Tap your badge against another attendee's badge. Both phones instantly receive a push notification with full contact details. No app needed to exchange.
Booth NFC Reader
Tap your badge at any booth's NFC reader. Your visit is logged, the startup gets your contact data, and you get their pitch deck sent to your phone.
Session Entrance Tap
Tap your badge at the session entrance NFC point. Your attendance is auto-tracked, no manual check-in, no QR scanning.
