1. Badge QR for Contact Exchange

Each attendee badge carries a unique QR. Scanning with the event app or a generic reader opens a profile or vCard download. This replaces business card exchange and keeps contact details current.

2. Session Check-In

Scan badges at session entry for attendance tracking. Automatic check-in data helps organisers understand popularity and schedule future events.

3. Exhibitor Lead Capture

Exhibitors scan visitor badges to capture contact details. GDPR and equivalent laws require informed consent; the consent flow must be clear before the scan or at the point of follow-up.

4. Networking Apps

Most conference platforms now embed QR networking: attendees scan each other and the platform facilitates introductions and follow-ups. This works best when the event app is adopted by most participants.

Frequently Asked Questions

Can exhibitors take personal data from a badge scan without permission?

No. Most jurisdictions require informed consent. Make the consent mechanism clear at registration.

What is the most reliable badge QR format?

A URL to the attendee profile or a vCard payload. URLs are more flexible; vCards work offline.
