Events with 50 or 500 attendees have the same requirement: every person needs a unique, scannable credential that gets them through the door and into the right sessions. QR codes on lanyard badges, printed tickets, or email PDFs are the practical standard for this. The challenge is generating a different code for every attendee efficiently.

BatchPrintGTIN's batch QR generator reads your attendee CSV — exported from Eventbrite, Google Sheets, Airtable, or any registration system — and produces a separate QR code for every row in under a minute. Free, no account, no server uploads. Download as a ZIP of PNG files or a multi-page PDF ready for badge printing.

🎉 Quick start: Export your attendee list as CSV (add a unique ID or URL per row), upload to the batch QR generator, select Text or URL type, download ZIP. Your attendee codes are ready in under two minutes.

Event QR Code Use Cases

Attendee Check-In Badges

A lanyard badge with a unique QR code per attendee is the fastest way to process check-in at an event entrance. Staff scan the code with a handheld scanner or smartphone; the check-in system marks the badge as used and optionally pulls up the attendee profile. For conferences with 300+ attendees, this reduces entry queues from 20+ minutes to under 5 minutes versus manual name lookups.

Session Access Control

For multi-session or multi-track events, different attendees have access to different rooms. Encode the access tier in the QR code data or URL. A sponsor-tier badge QR encodes a different identifier than a general admission badge. Scanning at each session door validates the correct access level before entry.

Digital Tickets

Email a PDF ticket with a unique QR code to each registrant. The code encodes a unique ticket ID. At the door, staff scan it and the system confirms validity and marks it used — preventing duplicate entry from forwarded emails. Generate all ticket QR codes at once from your registrant database export.

Exhibitor and Sponsor Lead Capture

Exhibitor booths at trade shows often use QR codes for lead capture: an attendee scans the booth code, which opens a contact form pre-populated with the booth ID. Generate a unique QR per exhibitor in the same batch as your attendee codes, using the URL type pointing to your lead capture form.

Session Feedback and Surveys

A QR code on the screen at the end of each talk or session that scans to a feedback form increases completion rates significantly compared to email-based surveys sent the following day. Generate one QR per session URL, print them on A5 tent cards placed on each seat.

Building the Attendee CSV

Export your registration list and format it for the batch generator. Two common structures:

Plain text ticket ID (simplest):

ticket_id,label
TKT-2026-0001,Sarah Chen
TKT-2026-0002,Marcus Williams
TKT-2026-0003,Priya Patel

URL-based check-in (links to your check-in system):

url,label
https://checkin.yourevent.com/verify?id=TKT-0001,Sarah Chen
https://checkin.yourevent.com/verify?id=TKT-0002,Marcus Williams
https://checkin.yourevent.com/verify?id=TKT-0003,Priya Patel

The URL approach enables smart check-in: scanning the badge opens the attendee record in your check-in system automatically, no lookup needed by staff. Plain text is simpler if your check-in system processes the raw ID directly from the scanner input.

Badge Printing Workflow

Once you have the ZIP of QR codes, the standard badge printing workflow:

  1. Open your badge template in Word, InDesign, Canva, or Google Slides — whichever you use for batch mail-merge.
  2. Set up a data merge using your attendee CSV (name, company, session track).
  3. Place the QR code image field in the merge — each record pulls its corresponding QR image file from the ZIP.
  4. Export as PDF or print directly. For professional conference badges, print on 300 gsm cardstock and cut to size, or use pre-punched badge sheets sized for standard lanyard holders.
💡 Error correction for badges: Use Level H (30% redundancy). Lanyard badges get bent, wet, and crumpled during events. Level H ensures the code scans even if nearly a third of it is damaged or obscured.

Frequently Asked Questions

How do I create unique QR codes for event attendees?

Export your registrant list as a CSV with a unique ID or URL per person and a label column with their name. Upload to the free batch QR generator, select Text or URL type, download ZIP. Each QR file is named by the attendee name. A 200-person event batch takes about 20 seconds.

Can QR codes replace printed tickets?

Yes. A QR code encoding a unique ticket ID or check-in URL fully replaces a printed ticket. Staff scan at entry; the system marks the code as used. For large events (500+), dedicated handheld scanners process check-in faster than smartphone cameras.

What error correction level should I use for event badges?

Level H (30% redundancy). Event badges get folded, bent, and worn throughout the day. Level H ensures reliable scanning even if nearly a third of the code is damaged or obscured.

How do I integrate QR check-in with Eventbrite?

Eventbrite generates its own QR codes for tickets, which integrate with their Organiser app. If you need custom QR codes (for session access control, lead capture, or a third-party check-in system), export your attendee list as CSV, generate codes in BatchPrintGTIN, and import them into your check-in platform. Many platforms including Whova, Swoogo, and Bizzabo accept external QR code imports.
