How to Set Up QR Code Check-In for Events: Step-by-Step Guide 2026

The concept is simple: each attendee gets a unique QR code (sent via email or on their ticket). At the event entrance, staff scan the QR code using any smartphone camera. The system marks them as checked in and your attendance list updates in real time.

There are two common setups:

1. Individual QR codes per attendee — each person has a unique code tied to their registration. Best for paid events, conferences, or anywhere you need to verify who is attending.

2. Single entry QR code — one QR code at the door links to a check-in form where attendees type their name. Best for free community events, workshops, or informal gatherings.

For most events, individual QR codes give you cleaner data and faster check-in.

Before you start, gather these components:

You do not need special hardware. Modern smartphone cameras scan QR codes instantly.

Before creating QR codes, decide what happens when an attendee scans their code.

Option A: Direct confirmation page Create a simple webpage (Google Sites, Notion, or your event platform) that shows the event name and date, a confirmation message, and schedule or session information.

Link each attendee's QR code to a unique URL like: yourevent.com/checkin?id=12345

Option B: Google Form check-in For smaller events, a Google Form works perfectly. Create a form with fields for name, email, and ticket type, set up a Google Sheet to capture responses, and all attendees scan the same QR code linking to this form.

Option C: Eventbrite, Townscript, or Konfhub If you registered attendees through an event platform, they already provide individual QR codes. You just need the scanning setup.

For most independent event organizers, Option A or B requires zero budget and works well for up to 500 attendees.

If you're generating individual QR codes (recommended for paid events):

Using QRForever: 1. Log in at qrforever.com 2. Use Bulk QR Creation — upload a CSV with attendee names and their unique check-in URLs 3. QRForever generates all QR codes at once and lets you download as a ZIP or PDF 4. Each QR code links to that attendee's specific confirmation page

Naming your QR codes: Use the attendee's name as the QR code label so you can identify each one in your dashboard.

Once generated, distribute QR codes via:

Email (most common): Embed the QR code image directly in the confirmation email. Include a backup link in case scanning fails. Send a reminder 24 hours before the event with the QR code again.

Digital tickets: Add the QR code to a PDF ticket using Canva or Google Slides. Attendees screenshot it to their phone — no printing needed.

Physical tickets: For premium events, print QR codes on physical tickets. Use a minimum size of 2.5 × 2.5 cm for reliable scanning.

Tip: Always include the attendee's name visibly on the ticket alongside the QR code so staff can cross-check manually if needed.

On event day, your check-in station needs 1 device per 100 expected attendees, adequate lighting at the scanning point, and a printed backup list for the first 30 minutes while connectivity stabilizes.

Staff briefing (5 minutes): Open the camera app, ask attendees to show their QR code, scan and confirm the green checkmark, then wave them through. For any failed scans, check the printed list manually.

Pro tip for large events: Set up two lanes — one for phone QR codes, one for printed tickets. This prevents the common bottleneck of people searching for emails.

With QR code check-in, you get data traditional sign-in sheets never could:

Scan analytics from QRForever: Total scans by time of day (see your peak arrival window), device types, and first scan timestamp per attendee.

Google Sheets tracking: If using Google Forms for check-in, your spreadsheet updates in real time. Share it with your event team so everyone can see who has arrived without needing to be at the entrance.

No-shows: Compare your registration list to your check-in data after the event. A high no-show rate (above 30%) is useful data for future events — consider overbooking or sending day-of reminders.

QR code won't scan: Screen brightness too low, QR code image is too small, poor lighting at entrance, or cracked phone screen. Always have a printed backup list.

Attendee forgot their QR code: Have a printed backup list sorted by name. If using Google Forms, they can check in manually by filling the form.

Slow internet at the venue: Download your attendance list as a PDF before the event. Have a paper sign-in sheet as backup for the first 15 minutes.

Duplicate check-ins: For paid events requiring strict access control, use a dedicated check-in app (Eventbrite, Konfhub) which marks codes as used after first scan.

Conferences and seminars: Use individual QR codes per attendee. Track which sessions they attended by placing different QR codes at each session entrance.

Weddings and private events: A single check-in QR code linked to a form works well. Guests appreciate not needing to find their name on a list — they just scan and fill their name in 5 seconds.

Corporate training and workshops: Individual QR codes double as attendance certificates. After the event, export your scan log as proof of attendance for HR or compliance records.

Recurring events (weekly classes, monthly meetups): Use one dynamic QR code per event series. Change the destination URL each week to that week's check-in form. The same printed QR code works every time — no reprinting needed.
