活动用QR Code：从注册到跟进
Event lifecycle QR codes: registration, badge check-in, session tracking, networking, feedback, and post-event follow-up.
QR Codes for Events: Registration to Follow-Up
QR codes streamline the entire event lifecycle — from pre-event registration through on-site experiences to post-event engagement.
Pre-Event: Registration and Invitations
- URL QR code on printed invitations linking to the registration page
- Calendar event QR with event date, time, and venue for "add to calendar"
- UTM-tracked links to measure which invitation channels drive registrations
On-Site: Check-In and Access
Badge check-in: Each attendee receives a unique QR code (in email or app) that is scanned at registration. This eliminates queues and captures attendance data.
Session access: QR codes at room entrances for session check-in — useful for tracking attendance across breakout sessions and workshops.
Access control: QR codes on wristbands or badges for VIP areas, speaker lounges, or age-restricted zones.
During the Event
Networking: Attendees scan each other's badge QR codes to exchange contact information (vCard or a link to their profile).
Session materials: QR codes on presentation screens linking to slides, handouts, or supplementary resources.
Live polling and Q&A: QR codes displaying at sessions for audience interaction via Slido, Mentimeter, or similar tools.
Sponsor engagement: Sponsor booths use QR codes for product demos, lead capture, and promotional downloads.
Post-Event: Follow-Up
Survey: QR codes on exit signage or in thank-you emails linking to event feedback surveys.
Content access: QR codes in post-event emails linking to recorded sessions, photo galleries, and presentation archives.
Networking follow-up: Scanned contacts trigger automated email sequences with mutual introductions.
Technical Considerations
- Venue WiFi QR codes ensure attendees can connect (important if the event app requires internet)
- Large venues need appropriately sized QR codes for scan distance
- Printed badges should use EC Level M or Q for handling wear
Key Takeaways
- QR codes streamline check-in, eliminating queues with scan-based registration
- Networking QR codes replace business card exchanges with digital contact sharing
- Session-level QR tracking provides granular attendance data
- Post-event survey QR codes on exit signage capture fresh feedback
- Venue WiFi QR codes reduce connectivity friction for event apps
