How Event Badge QR Codes Work
An event badge QR encodes the attendee's vCard (contact information) plus the event name and session track. When scanned with any modern phone camera, the recipient's phone prompts to save the contact — with the event name preserved in the NOTE field so they always remember where they met.
This is the format trade shows, conferences, speaker programmes, sponsor booths, and networking nights have standardized on because it works on every phone without an app.
Designed for the Three Badge Layouts You Actually Print
- Vertical attendee badge — portrait orientation, lanyard clip at top, conference logo at the top, attendee name centered, QR at the bottom corner. The most common modern layout.
- Horizontal speaker / staff badge — landscape orientation, role band across the top, larger name treatment, QR on the right side.
- Sponsor / exhibitor booth card — tabletop or hanging signage with the booth name, company logo, and a larger QR that visitors can scan from a few feet away.
The generated QR works in all three. Pair it with your existing badge template in Canva, Figma, Illustrator, or the badge-printing service your event uses.
What the QR Actually Contains
A vCard 3.0 string with these fields filled in:
- FN / N — formatted and structured name so the contact saves with correct display order.
- ORG, TITLE — company and role.
- EMAIL, TEL, URL — the optional fields attendees want to share.
- NOTE — event name and session track joined with an em-dash. Months later the recipient's contact app still shows "Abundera Summit 2026 — Main Stage", so they remember the context.
Print Considerations
- Minimum size — 20 mm (0.8 in) square. Smaller QRs force attendees to rescan or press their phone flat against the badge.
- Quiet zone — keep at least 4 modules of white space around the QR. Do not run the badge border or lanyard clip area into the quiet zone.
- Substrate — matte badge stock or laminated PVC works. Avoid glossy laminate that glares under overhead lighting.
- ECC — High (30%) is overkill for names; Medium is fine unless the badge will get physically abused (wet, folded, covered in stickers).
- Vertical placement — the QR should sit above the name tag cutout so attendees can scan without the lanyard flapping.
Use the Print Size Calculator
Our Print Size Calculator tells you the exact minimum QR size for any attendee-to-attendee scan distance. A close-range badge-to-phone scan works at around 3 cm across; a sponsor booth QR scannable from across a table aisle needs 10 cm or more.

Frequently Asked Questions
What is the difference between an event badge QR and a regular vCard QR?
They both encode a vCard, but the event badge type adds an Event Name and Session / Track field that get written to the vCard's NOTE field. Months after the event, the recipient's contact app still shows 'Abundera Summit 2026 — Main Stage' alongside your name, which preserves the context. A plain vCard QR just carries contact info.
Will every attendee's phone save my contact?
Yes — vCard 3.0 is natively supported by iOS Camera, Google Lens, Samsung Camera, and every other modern phone camera. The phone shows an 'Add to Contacts' prompt on scan. No app required.
Can I add a conference logo to the QR code itself?
The generator supports a centre logo (upload any PNG or SVG) and keeps the QR scannable by raising error correction automatically. For sponsor booth signage with two logos (the conference AND your company), put one logo in the QR centre and the other on the printed badge next to the QR — not inside the QR quiet zone.
What if the attendee doesn't share their details online?
Encode only what they consent to share. Name is the only required field; company, role, email, phone, and URL are all optional. Many events generate the QR with just Name + Company + Event Name so attendees can scan each other without exchanging email.
Can I generate hundreds of badges at once?
Yes — use the Batch CSV feature. Upload a spreadsheet with one row per attendee (first, last, org, title, email, phone, event, session, URL) and export 500 QR codes at once, ready to drop into your badge template.
Should I use the Business Card Designer too?
The Business Card Designer is for traditional wallet-sized business cards. For event badges, design the badge in your existing layout tool (Canva, Figma, Illustrator) and drop the downloaded PNG or SVG into the QR placeholder. Badge printers generally want you to hand them a flattened PDF with the QR already placed.
How long should the QR stay valid?
The QR carries static vCard data — no server, no expiration, no revocation. It works forever and keeps working even if this site goes away. That said, when attendees leave a company their contact info goes stale, which is a limitation of any vCard (not of the QR).
