Prepare the public card first
Publish a concise profile with the name, role, organization and contact action that should remain useful after the event. Review public visibility and remove details that do not belong on an openly shared page.
A better introduction
Build an event badge that supports the conversation.
Prepare an event badge with a tested QR code, readable identity, permanent digital card, fallback link and a responsible post-event follow-up process.
Keep the badge readable
Use large text for the attendee name and enough contrast for the expected venue lighting. Show the organization or role as text, and position the code where a lanyard or badge holder will not cover it.
Export and test the final badge
Generate the QR image from the permanent card address, export the actual badge artwork and scan a physical proof. A screen preview does not expose every scaling or print-quality problem.
Plan the post-event path
Make the card useful even if the visitor does not submit a lead. If contact information is collected, explain the purpose and follow up in the context of the conversation rather than treating a scan as broad marketing consent.
Should the badge show only a QR code?
No. The attendee name and relevant organization or role should remain readable without a device, connection or successful scan.
Can the same badge QR code be used after the event?
Yes. A permanent card address can remain useful in follow-up material, provided the published profile stays accurate and intentionally public.
