Event Badges from Registration to QR Check-in: A Complete Guide

An event badge workflow has five stages: collect registrations, generate badges, print or send them, check attendees in at the door, and use the badges for networking during and after the event. Planning each stage up front avoids the last-minute scramble.

The five stages

1. Registration: your ticketing platform collects name, company, job title, ticket type and email.
2. Badge generation: you export registrations and import them into a badge template, one badge per attendee.
3. Printing and distribution: you print badges in advance, print on site, or send digital badges by email.
4. Check-in: staff scan each badge's QR code at the entrance to mark the attendee as arrived.
5. Networking: attendees and sponsors scan badges to exchange contacts.

Who owns what

• Registration team: clean data and ticket types.
• Design or brand: the badge template and role colors.
• Operations: printing, badge pickup, help desk and scanners.
• Sponsors: lead capture at booths.

Getting these roles clear early means a late name change has an obvious owner. The event badge maker keeps the template, data and reprints in one place.

The most common lanyard badge is 4 × 3 in (about 102 × 76 mm) landscape, with 3 × 4 in portrait, A6 (105 × 148 mm) and CR80 cards (85.6 × 54 mm) also widely used. Choose a size that matches your holders before you design.

Design for reading distance

People read badges from across a conversation, not from a desk.

• First name: at least 24 pt and bold. It is the most important thing on the badge.
• Last name: smaller, beneath the first name.
• Company and job title: smaller again.
• Role band: a strip of color with text such as SPEAKER, SPONSOR, STAFF or PRESS, readable at a glance.
• QR code: near the bottom edge, so it can be scanned without lifting the badge far.

Front and back

Lanyards twist, so many organizers print the name on both sides. If you only print one side, put the event agenda, WiFi details or venue map on the back.

Common design mistakes

• Event logo larger than the attendee's name.
• Light gray text on white.
• Long company names that wrap onto three lines. Set a character limit or a smaller font for long values.
• QR codes under 2 × 2 cm, which scan slowly in a busy entrance.

Export registrations from your ticketing platform as CSV or Excel, upload them to your badge tool, and map each ticket type to a role variant of one badge template.

Prepare the export

• One row per attendee, headers in the first row.
• Columns for first name, last name, company, job title, ticket type, email and a unique ticket or order reference.
• Clean up capitalization ("ACME LTD" to "Acme Ltd") and trim long job titles.
• Save as XLSX or CSV UTF-8 so international names display correctly.

Map ticket types to roles

Create one template with a variant per role, such as General, Speaker, Sponsor, Staff, Press and VIP. Each variant changes the role band color and label. Then map ticket types to variants: "Early bird" and "Standard" both become General; "Exhibitor" becomes Sponsor.

Generate in bulk

Upload the export to the batch generator, map columns to fields and generate every badge in one job. Each attendee gets a unique QR code linked to their ticket reference.

Handle late registrations

Registrations keep arriving. Re-import the updated export with the same ticket reference column: existing badges stay as they are, new attendees get new badges, and changed rows update.

Print in advance for most attendees and keep a small on-site printer for late registrations and corrections. Pure on-site printing is fastest to change but can create queues at peak arrival times.

Printing in advance

• Print in alphabetical batches by last name so pickup tables can be split A–F, G–L and so on.
• Print a sample sheet first and check alignment, role colors and QR codes.
• Pack badges with holders and lanyards ready to hand over.

On-site printing

• A help desk with a laptop and printer handles name corrections, lost badges and walk-ins.
• Because each badge comes from the same record, a corrected badge is a single reprint, not a new batch.

Digital badges

Send each attendee their badge by email ahead of the event. They show the QR code on their phone at the door, and you print a physical badge at check-in or skip printing altogether for smaller events.

Which plan

Event badges are part of the CardDeck Business plan. For a one-off event without an annual plan, contact the team about per-event badge runs.

Each badge carries a unique QR code tied to the attendee's ticket reference. At the entrance, staff scan the code with a compatible check-in app or scanner, which marks the attendee as arrived and flags duplicates or invalid tickets.

Setting up check-in

1. Decide on your check-in tool: a check-in app on staff phones or tablets, or dedicated 2D scanners. CardDeck badge QR codes work with compatible check-in apps and scanners; it does not sell check-in hardware.
2. Test scanning printed badges and phone screens before the event.
3. Plan enough scanning points for peak arrival. Watch the first wave and add a lane if the queue grows.
4. Have a manual fallback: a searchable attendee list for people who forgot or damaged their badge.

Make codes fast to scan

• At least 2 × 2 cm on printed badges, larger if scanned from further away.
• Dark code on a light background with a clear margin.
• Near the bottom edge of the badge, not hidden by a lanyard clip.
• Phone screen brightness turned up for digital badges.

After the doors open

Use the same badge QR for session check-in or room capacity if your check-in tool supports it, and keep the help desk open for reprints throughout the day.

When each badge's QR code links to the attendee's profile, attendees can scan each other to save contacts, and sponsors can scan badges to capture leads, instead of swapping paper cards that rarely get entered.

For attendees

A scan opens the other person's profile in the phone's browser, with a button to save the contact. No app is needed. Attendees control what their profile shows.

For sponsors and exhibitors

Booth staff scan attendee badges and the contacts flow into contact management, tagged with the event and booth. After the event, they export leads to CSV or their CRM instead of typing up a pile of business cards.

For organizers

You see engagement across the event, and badges keep working as profile links after the event ends, which gives attendees a reason to keep them.

Privacy basics

• Tell attendees at registration that their badge links to a profile and what it will show.
• Let attendees choose what to share.
• Only capture lead details with consent; CardDeck's contact form records consent and timestamp with each contact.

We cover this in more depth in turning event badges into networking cards.

Run a help desk with a laptop, a badge printer and blank stock, and fix every change in the attendee record before reprinting. Because each badge is generated from that record, a correction is a single reprint, and check-in and networking keep working.

Changes you should expect

• Misspelled names and wrong companies from registration typos.
• Substitutions, where a colleague attends in place of a registered attendee.
• Role upgrades, such as a late speaker or a new sponsor representative.
• Lost or forgotten badges.
• Walk-in registrations on the day.

A simple help desk process

1. Find the attendee by name or ticket reference.
2. Correct the record: name, company, role or ticket type.
3. Reprint that one badge. The role variant updates automatically if the ticket type changed.
4. For substitutions and lost badges, make sure the old badge no longer checks in, if your check-in tool supports it.
5. Hand over the new badge with a holder and lanyard.

Keep the queue short

• Put the help desk next to, but separate from, the main pickup tables.
• Keep the busiest pickup period free of reprints where possible by fixing known changes the night before.
• Have one person whose only job is reprints during the first hour.

After the event

Export the final attendee list with check-in status. It is the most accurate record you will have of who actually attended, and it makes next year's import cleaner.

Work backwards from the day doors open. Most badge problems come from leaving design and data checks until the final week.

Timeline

• Six weeks out: choose badge size and holders, decide roles and colors, build the template.
• Four weeks out: agree the registration fields you need for badges; make sure your ticketing form collects them.
• Two weeks out: run a test import with real registrations, print samples, test QR scanning with your check-in tool.
• One week out: import the full list, fix flagged rows, and print the first batch. Order extra blank stock.
• Two days out: import late registrations and changes, print the second batch.
• Event day: set up check-in lanes and a help desk with a printer for reprints.

Day-of checklist

• Badges sorted alphabetically with holders and lanyards.
• Scanners or check-in devices charged, with spares.
• A searchable attendee list as a fallback.
• Blank badge stock and a printer at the help desk.
• Signs for pickup lanes and the help desk.

Common mistakes

• Waiting until the final week to see real data in the template.
• Role colors that are hard to tell apart under venue lighting.
• No process for name corrections, which creates a queue at the busiest moment.
