How to Create a Survey with a QR Code

You have finished building your online survey and now you just need participants? This is exactly where the QR code comes in. Instead of typing out a long link or forwarding it, people simply scan a code with their phone and land directly in your survey. That works on a poster in the stairwell just as well as on the back of a business card, on a stand-up display in a shop, or on a slide at the end of your talk. In this article, we show you step by step how to create a survey and share it with a QR code, what to keep in mind when generating it, and how to avoid the typical mistakes that end up costing you participants.

 

📌 Key points at a glance:

• A QR code for your survey is nothing more than your survey link in machine-readable form. You create it from the link, either with a QR generator or directly inside your survey tool.
• QR codes pay off everywhere people are meant to come across your survey offline: on posters, flyers, stand-up displays, receipts, presentation slides, or at an event venue.
• With empirio.ai you create your survey for free, get the participation link, and can turn it straight into a QR code. It is privacy compliant, with all data stored 100% within the EU.

Survey with a QR code: what is actually behind it?

A QR code is essentially just another way of showing your survey link. Instead of an address you click on, you get a square black-and-white pattern that a phone camera reads in seconds. When the participant taps the address that pops up, your survey opens in the browser, with no app, no account, and no typing.

The key point: the QR code itself does not "contain" a survey. It only points to the link behind which your survey sits. As long as that link is reachable, the code works too. If the survey is deleted or closed, the scan leads nowhere. So with a QR code you are not building a second, independent survey, you are building a convenient bridge from the real world to your online questionnaire.

That is exactly what makes it so practical. Wherever your target group happens to be physically, in the waiting room, in the seminar room, at the shop counter, at the club party, you can bring them into your survey without a detour.

 

QR code or link: when do you use which?

Both have their place, and in practice you often use both in parallel. A rough rule of thumb:

• QR code whenever your participants are looking at something printed or displayed: a poster, flyer, stand-up display, receipt, projected slide, or shop window.
• Link whenever your participants are already on a screen anyway: email, messenger, social media post, intranet, newsletter.

 

If you send your survey via messenger, for example, you are better off with the plain link. We show you exactly how that looks in our article on running a survey through WhatsApp. But as soon as paper or a screen comes into play, the QR code is almost always the faster route.

 

Create a survey with a QR code: step by step

The process is always the same, no matter which survey tool you work with. First you need a finished survey with a shareable link, then you turn that link into a QR code. Let us walk through the five steps.

1. Create and publish the survey

Before you even think about the QR code, the survey itself has to be ready. Set up your questions, check the order, and make sure the survey looks good on a phone, since the vast majority of QR code scans happen on mobile anyway. Only once the survey is published do you get a stable participation link that no longer changes.

If you are still unsure how to build your questions, our guide on how to create a questionnaire properly will help. That is worth doing before you send the code out into the world, because you cannot fix anything afterwards on a printed poster.

2. Copy the participation link

Your survey tool has a section for sharing or distributing the survey. There you will find the public link that participants use to open the survey. This link, not the editing or preview address from your account, is the basis for the QR code. Copy it out.

3. Generate the QR code

Now you turn the link into the pattern. You have two ways to do that:

• Directly in the survey tool: Many tools, including empirio.ai, offer a QR code right alongside the sharing options. You do not have to copy anything, you simply download the code directly. This is the most convenient and safest route, because the link and code are guaranteed to match.
• Through a separate QR generator: Alternatively, you paste the copied link into a QR code generator and have the code created there. That works, but you should pay attention to a reputable provider (more on that shortly).

4. Test the QR code

This step is skipped most often, and it is the most important one. Scan the finished code with your own phone, ideally with a second device as well. Does your survey really open? Can it be filled in to the end and submitted? Only once that works cleanly is the code ready for printing.

5. Place and distribute the QR code

Finally, you put the code where your target group will see it: on the poster, the flyer, the stand-up display, the presentation slide. It is important that the code is large enough and does not get lost between other text. We will take a closer look further down at exactly how to place and label it.

 

💡 Practical tip:

Generate the QR code as late in the process as possible, that is, only once the survey is finally published. That way you avoid printing a code that points to a preview or test version and stops working later.

 

Generate a QR code for your survey with empirio.ai

If you create your survey with empirio.ai, you do not need an extra tool for the QR code. The process stays the same as above, except that steps 2 and 3 merge into one.

You create your survey, with AI support if you like, so that you do not start from a blank page, and publish it. In the sharing section you then find both the participation link and the matching QR code, which you can download directly and build into your poster or flyer. The link and code come from the same source, so nothing can drift apart.

Creating a survey is free with us, you only need an email address, no credit card. We describe how this works without any hurdles in detail in our article on creating an online survey for free and without signing up. A pleasant side effect: your participants' answers are stored 100% within the EU, a point that quickly becomes important with QR code surveys in public spaces, because you never know exactly who is scanning.

Choosing the right QR code generator

If you do use a separate generator, the choice of provider is not a side issue. QR codes all look the same, but there is one important difference below the surface.

Static and dynamic QR codes

There are two basic types, and the difference decides how flexible you are later on.

• Static QR code: The link is stored permanently in the pattern. Once printed, it can no longer be changed. If the code points to an address that no longer exists, it is worthless. In return, it is usually free and not tied to any service.
• Dynamic QR code: The pattern points to an intermediate address belonging to the provider, which you can redirect to a new target at any time. The printed code stays the same, the target is adjustable. That is handy, but it ties you to a service provider, and it is often paid.

 

For most surveys, a static QR code is completely sufficient, as long as your survey link stays stable. Dynamic codes pay off mainly when you use the code over a long period and expect to switch the target in between.

What to look out for in a generator

If you use an external provider, check a few points in advance:

• No expiry date on static codes. Some services produce seemingly static codes that in reality run through a redirect and get deactivated after a trial period. Make sure a genuine static code works permanently.
• A file in good quality. You should be able to download the code as a vector file (SVG) or as a high-resolution PNG, otherwise it becomes blurry on large posters.
• A responsible approach to data. Dynamic codes often record scan statistics. Clarify what the provider stores, especially when your survey itself is sensitive in terms of data privacy.
• No mandatory account. For a simple static code, you should not have to register anywhere.

 

The easiest way to save yourself all of this: generate the QR code directly in the survey tool instead of putting a third-party provider in between.

 

Placing the QR code correctly: how to get more people to scan

A QR code only brings in participants if it is seen, understood, and easy to scan. Three things decide that.

Size and placement

The code has to match the distance it is scanned from. On a flyer held in the hand, a small code is enough. On a poster hanging on the wall six feet away, it has to be considerably larger. As a rough guide: the further away the viewer, the larger the code. On top of that, do not place it too low (people do not like bending down) and not behind glass with strong reflections.

Contrast and a quiet border

QR codes need contrast. A dark pattern on a light background works reliably, light codes on a dark or colorful background often do not. Also leave a small white border free all the way around (the so-called "quiet zone"). If the code is squeezed right up against text or image edges, the camera struggles.

A clear call to action next to it

A bare QR code tells nobody what to expect. Write a short sentence next to it explaining what it is about and why the scan is worth it, for example: "Scan the code and give us feedback on our service in 2 minutes." A concrete time estimate and a clear benefit noticeably increase willingness to take part.

 

Location	Scan distance	What to watch out for
Flyer / handout	Close (in the hand)	A small code is enough, with a clear call to action next to it
Poster on the wall	3–10 feet	A considerably larger code, placed at eye level
Stand-up display / table card	Close to medium	Not behind reflective glass, with good contrast
Receipt	Close	Check the print quality, do not make the code too small
Presentation slide	Variable (room size)	Leave the slide up long enough, code large enough for the back rows

 

Typical mistakes with QR code surveys, and how to avoid them

Most problems do not arise when generating the code, but before and after. We see these stumbling blocks again and again.

• The code points to a preview instead of the real survey. If you create the code from a test or draft address, you print a code that later leads nowhere. Always use the final, public participation link.
• The code was never tested. A single test scan before printing would have prevented many dead codes. Test with at least two devices, ideally iOS and Android.
• The code is too small or too low in contrast. On large posters or a colorful background, the camera fails. Enough size, a dark pattern on a light background, a quiet border.
• No explanation next to it. A code without context gets ignored. Say in one sentence what happens when someone scans, and how long it takes.
• The survey is unusable on a phone. QR code participants almost always come in on mobile. If the survey is unreadable on a phone or takes forever to load, they drop off. Test on mobile beforehand.
• The survey is closed too early. Posters often hang up longer than the survey is open. Think in advance about how long you want to collect answers, and plan the period generously.
• Data privacy not thought through. In a public space, anyone who wants to can scan. Make sure you only collect what you really need, and use a tool with clean data processing.

Where QR code surveys really pay off

QR codes play to their strengths everywhere your target group is out and about offline. A few typical situations from practice:

Customer feedback at the point of sale

A small stand-up display at the register, a code on the receipt or at the table in the café, and customers give feedback right there on the spot. The advantage: you reach people exactly when the impression is still fresh. For meaningful results, though, you should consider whether the answers give a realistic picture, that is, whether your survey is representative or more of a snapshot of the mood.

Events, trade fairs, and talks

Show a slide with a QR code at the end of a talk, put up a stand-up display at the trade fair booth, lay a code on the tables at the club party, that way you collect feedback while people are still there. The only important thing is that the code stays visible long enough so that the back rows also have time to scan.

On-site surveys: waiting room, school, club

In the waiting room of a practice, in the classroom, in the clubhouse, anywhere people are briefly waiting or coming together anyway, a QR code poster is a low-barrier invitation to take part.

Academic surveys

For a survey as part of a thesis too, the QR code can help, for example on a notice on the bulletin board or on a handout in the cafeteria. But it does not replace a well-thought-out distribution strategy. You can read about how to systematically reach enough people in our article on how to find participants for your online survey.

 

If you are still looking for a suitable structure for your survey, our survey templates offer ready-made examples for customer feedback, event surveys, or club surveys, which you can adopt, adapt, and then distribute via QR code.

 

Data privacy with QR code surveys

As soon as your QR code is hanging up in public, you no longer have any control over who scans it. That is exactly why data privacy deserves special attention here, more than with a survey you send specifically to people you know.

Three points are particularly relevant:

• Only collect what you need. The less personal data you ask for, the less problematic the whole thing is. For many feedback surveys, a completely anonymous response is enough.
• Transparency for participants. Whoever scans should be able to recognize who is behind the survey and what happens to the answers. A short note and a link to the privacy policy belong here.
• Where the data is stored. Where the answers end up is a topic especially with surveys of customers, employees, or other people. A tool that stores the data within the EU makes your life considerably easier.

 

This does not apply specifically to QR codes, but to online surveys in general. The QR code only makes the topic more visible, because your survey is suddenly reachable for every passerby. You can find a detailed overview, including sample texts, in our guide to data protection and GDPR for surveys.

 

Conclusion: the QR code is the bridge between poster and survey

Creating a survey with a QR code is not a separate, complicated procedure, it is the last, simple step once your survey is ready. You take the finished participation link, turn it into a code, test it, and bring it to where your target group is. This works most conveniently when your survey tool supplies the QR code straight away, so that the link and code are guaranteed to match.

What ultimately decides success is not technical tricks, but care: use the final link, test the code, place it large and high in contrast, write a clear note next to it, and leave the survey open long enough. Anyone who follows these points turns a poster, a flyer, or a presentation slide into a reliable channel for real answers.
