How to Create a QR Code Survey (and Get People to Finish It)

A paper feedback card gets read by nobody and typed up by even fewer. A QR code survey fixes both problems: the person standing in front of your sign, receipt or table tent scans it, answers a few questions on their phone in under a minute, and the answers land in a dashboard you can read the same day. This guide covers how to design one that people actually finish, where to put the code, and how to read the results without fooling yourself.

Note: the survey builder in ScanTraceQR needs a free account, because you need somewhere to manage questions and see responses. The people answering do not need one.

When a QR code survey is the right tool

QR surveys work best when the audience is physically present and has a phone in hand, and when the survey is short:

• Customer feedback at a cafe, salon, shop counter or hotel room.
• Event feedback on the last slide, on badges or on seat-back cards.
• Lead and sign-up forms at a trade-show booth, where a name and email is all you need.
• Classroom or workshop check-ins, such as a quick poll at the start and end of a session.
• Field data collection, for example a tick-box inspection form on a poster at a site entrance.

It is a poor fit for long research questionnaires, anything that needs respondents to prove who they are, or audiences who will not be near the printed code. For those, send a link by email instead.

Step 1: Decide the one thing you want to learn

The most common reason surveys fail is that they try to answer five questions at once. Write down the single decision the results will change, such as “should we keep the Saturday opening hours?” or “which workshop topic do we run next?” Then keep only questions that help with that decision. If you cannot say what you would do differently after reading an answer, drop the question.

Step 2: Write questions people can answer on a phone

Thumbs are slower than keyboards, so choose the fastest answer type that gets you the information:

• Yes / no and 1–5 ratings take one tap and give you numbers you can average and compare over time.
• Single choice and dropdown suit questions with a known set of answers, such as “How did you hear about us?”.
• Multiple choice fits “select all that apply” questions. Keep the list to about six options.
• Short text is for one-line answers like a name, and long text for open comments. Use at most one open comment box; it is where the best insights come from, and also where people give up.
• Email, phone, number and date fields validate their input, so you do not end up with “n/a” in the phone column.

Aim for five to eight questions. A good order is: an easy rating first to get people started, the specific questions in the middle, the optional open comment last, and contact details only at the very end and only if you truly need them.

Step 3: Build it in ScanTraceQR

1. Create a free account (or log in), then open Surveys.
2. Create a survey and add your questions. Pick the type for each, mark required ones, and for choice questions type one option per line. Drag questions to reorder them.
3. Add branding so the form looks like it came from you: a logo, company name, header line and a short description.
4. Set what happens afterwards: show a thank-you message, or send respondents on to a web page such as your booking page.
5. Choose your settings: one response per device or unlimited, an optional close date, and whether to record approximate location and device (respondents see a notice if you do).
6. Open the QR page to download the code, or print it directly.

The survey lives at a short address of the form scantraceqr.com/s/code, and the QR code simply points to it. You can share that same address by text or email for people who are not near the printed code.

Step 4: Place the code where people are waiting

The best placement is wherever there is a natural pause. A cafe table tent, the back of a receipt, a poster in a waiting room, or the final slide of a talk all work. Put one sentence next to the code that says what it is and how long it takes: “Two minutes, five questions: tell us how we did.” A code with no explanation looks like an advert and gets ignored. For sizing and printing, the rules in our QR code size guide apply: keep the white margin, use high contrast, and test with more than one phone before you print a batch.

If you run several locations or events, make one survey per place, so that the results are already separated when you open the dashboard.

Step 5: Read the results honestly

Each survey has a dashboard with the total number of responses, responses over time, and a chart for each question: bars or pies for choice questions, a histogram and average for numbers and ratings, and the most common words for free-text answers. Everything can also be exported as a CSV with one column per question, ready for a spreadsheet.

A few cautions when interpreting the numbers:

• Small samples mislead. An average of 4.8 from nine responses tells you much less than 4.3 from three hundred. Wait before acting on early results.
• Self-selection is real. People with strong opinions, good or bad, are more likely to respond. Treat the results as a signal, not a representative poll.
• Compare like with like. Use the same rating question across weeks or locations, and look at the trend, not a single day.
• Read the comments. Charts tell you what; the open answers tell you why.

Privacy: collect less than you could

Because respondents are anonymous by default, a survey with no name or email questions collects very little personal data. If you do ask for contact details, tell people why and only use them for that purpose. Recording approximate location and device can help you compare venues, but it counts as extra data, so switch it on only if you will use it, and keep the notice visible. Our guide to GDPR and IP addresses explains how to think about that. Do not use a survey to collect sensitive information such as health details, passwords or payment data.

Common mistakes

• Too many questions. Completion drops with every extra screen of scrolling. Cut until it fits in about a minute.
• Leading wording. “How great was your visit?” biases the answer. Ask “How was your visit?” and offer a balanced scale.
• Two questions in one. “Was the staff friendly and fast?” cannot be answered if they were friendly but slow.
• No close date. Old posters keep collecting answers about a change that is long over. Set a close date for event surveys.
• Never testing it. Scan the code yourself on a phone and complete the form before you print anything.
