QR Codes for Event Marketing: Sign-Ups to Check-In

QR codes for event marketing work best when every printed piece gets its own code: one on the flyer, one on the mailed invitation, one on the booth banner, one on the badge. Each code sends people to a single next step, such as the registration page, the schedule, or a lead form, and each one counts its own scans, so you can see which piece brought people in. You can create an event QR code on QRelix with no credit card. Each free code works for its first 50 scans and shows a brief QRelix screen before forwarding, and Pro ($5.99/month) removes both limits. More event setups are on the QR codes for events page.

What QR codes for event marketing can tell you

Event budgets are hard to attribute. You pay for flyers, a mailing, a sponsor banner, and a booth, and the registration report shows only a total. A code on each piece closes that gap, because a scan is a record of someone acting on that specific piece.

Every QRelix code is dynamic. The printed pattern holds a short redirect link, the redirect logs the scan, and the visitor is forwarded to the page you chose. For each code, the dashboard shows:

Total scans and unique visitors, so repeat scans by one person do not inflate the count.
City, region, and country, estimated from the scanner's IP address.
Device, operating system, and browser.
Time of scan, with a chart of activity by hour and a daily trend.

Scans appear in real time, so you can watch a code during the event itself. No names, emails, or phone numbers are recorded. To learn who someone is, point the code at a form and let them tell you.

Because the redirect sits between the print and the page, you can also change the destination after printing. That is what lets one badge or program serve the whole event, from sign-up through follow-up.

Before the event: codes that drive registrations

Give each promotion piece its own code and send all of them to the same registration page. Name each code after where it will live, such as "Flyer, campus coffee shops" or "Invite, past attendees," so the numbers are easy to read later.

Flyers and posters. One code per location type. A code on gym noticeboards and a code on cafe counters tell you which venues are worth a second print run.
Mailed invitations. A code next to the RSVP line saves typing a URL from paper.
Print ads and partner handouts. A separate code per partner shows who sent you registrations.
Save the date. The free event QR code generator makes a code that adds the event to a phone's calendar. That code is static, so it cannot be tracked or edited. Use it for the date itself and use a dynamic code for anything you want to measure.

Scans tell you who picked up a phone. To see who went on to register, add UTM tags to the destination URL so each code shows up as its own source in your site analytics. The QR code tracking in Google Analytics 4 guide has the tag format, and QR campaign tracking covers comparing channels side by side.

At the event: check-in, schedules, and booth leads

If you sell tickets through a ticketing service, the code on each ticket comes from that service. The codes below are the ones around it, which you control.

Check-in and sign-in. A code at the door that opens a sign-in form replaces the paper sheet and gives you a timestamped list.
Schedule and venue map. Print one code in the program that opens the schedule page. When a session moves rooms, edit the page or the destination and every printed program follows. The Maps type opens directions to the venue, and a PDF page (under Hosted pages) shows the program right on the phone.
Guest WiFi. A WiFi code on table tents connects attendees without reading out a password. The WiFi QR code generator makes a static one in your browser with no signup.
Booth lead capture. Point a code on the banner at a three-field form. A Survey page (under Hosted pages) hosts the form for you, or you can link to the form tool you already use. The QR code lead capture guide covers the form and the follow-up.
Speakers and sponsors. A Business card page (under Hosted pages) on a badge lets the scanner save contact details in one tap.
Session feedback. Put a code on the closing slide and at the exits. Two questions get answered. Ten do not.

Make one code per session or per booth if you want separate numbers. Both QRelix plans include unlimited dynamic codes, so extra codes cost nothing.

After the event: follow-up from the same printed codes

The badge, the program, and the swag are still in people's bags the next week. Because the codes are dynamic, you can re-point them without reprinting anything:

The schedule code now opens session recordings and slides.
The booth code now opens a "book a call" page instead of the giveaway form.
The swag code opens early registration for next year's date.

On the free plan this works until a code reaches 50 scans. A code you expect to keep in use after the event belongs on Pro.

A worked example: one conference, three codes

A 300-person regional conference promotes registration with three printed pieces. Each has its own code and its own UTM tag, and all three open the same registration page.

Mailed invitation to 500 past attendees: 118 scans, 41 registrations.
Flyer at 40 coffee shops: 62 scans, 9 registrations.
Banner at a partner's trade show: 27 scans, 12 registrations.

Divide registrations by scans. The invitation converts at about 35%, the flyer at about 15%, and the banner at about 44%. The banner had the fewest scans and the best rate, the invitation brought the most people, and the flyers cost the most effort per registration. Next year the organizer mails more invitations, books a second partner banner, and halves the flyer run.

The plan matters here too. The invitation and flyer codes both passed 50 scans, so this campaign needs Pro to keep them working. The banner code at 27 scans would have fit the free plan.

Print and placement rules for event QR codes

Size the code for the distance. At least 2 cm (0.8 in) wide for badges and programs held in the hand, 5 cm (2 in) for posters read from 1 to 2 meters, and 15 cm (6 in) for banners read from 3 meters or more. When in doubt, go bigger.
Download SVG for print. It stays sharp at any size. Sizing and file formats are in the printing guide.
Keep a clear margin. Leave empty space on all four sides and keep text and borders out of it.
Say what the scan does. "Scan to register" or "Scan for today's schedule" next to the code beats a bare code.
Give slides time. Leave a code on screen long enough for the back row to raise a phone and focus.
Test the printed piece. Scan a proof with an iPhone and an Android phone from the distance attendees will stand at.

Free plan or Pro for an event?

The free plan needs no credit card. It includes unlimited dynamic codes, every QR code type, editable destinations, custom colors and logo, and the full analytics dashboard. Each free code works for its first 50 scans and shows a brief QRelix screen before forwarding. After 50 scans the code pauses until you upgrade, and nothing is deleted. That fits a workshop, a dinner RSVP, or a test of two flyer locations.

Pro is $5.99 per month. It makes scans unlimited, removes the QRelix screen, and adds Smart Routing and a Brand Kit. Expiration dates and passwords are free on every plan: an expiration date suits an early-bird code that should stop on a set day, and a password suits a speaker or VIP page. There is no per-scan fee and no long-term contract, and if you cancel, your codes return to the free plan's limits. The dynamic QR code cost guide works through the math, and current details are on the pricing page.

Common questions

Can I change where an event QR code goes after it is printed?

Yes. Edit the destination in your QRelix dashboard and the next scan opens the new page. The printed code stays the same.

Can I see who scanned my event QR code?

No. You see counts, times, locations, and devices, with no names or contact details. To collect those, send the scan to a registration or lead form.

Do attendees need an app to scan?

No. The camera on a current iPhone or Android phone reads QR codes without an extra app.

Should every session or booth have its own code?

Yes, if you want to compare them. A shared code gives you one combined number with no way to split it afterward.

Next steps

Create your event QR code, print one flyer, and scan it yourself to see the first entry in your dashboard. Then make one code per placement before the full print run. For more placements and code types, see QR codes for events.
