What is QR-code survey?
A QR-code survey is a questionnaire accessed by scanning a QR code with a smartphone or tablet camera, which opens the survey URL so participants can respond quickly without typing a long web address. It's a mobile-first way to share surveys on printed materials, screens or signage.
A QR-code survey uses a QR (Quick Response) code that encodes a link to an online form or questionnaire. When someone scans the code with a phone camera or QR app, the device opens the survey in a browser. Because QR codes are visual and require only a quick scan, they remove the friction of typing URLs and make it easy to connect in-person audiences to digital surveys — for example on posters, flyers, event badges, receipts, or facility signage. The survey itself is a regular web form and works with any mobile-friendly survey platform; on multilingual platforms like Hearo, the landing experience can offer automatic translation or let participants choose their preferred language.
Usage example
A school prints posters advertising a parent feedback survey with a large QR code. Parents scan the code on drop-off, the survey opens on their phones in their preferred language, and they complete the form without creating an account.
Practical application
QR-code surveys increase response rates by making it easy for people to start a survey immediately from the place where they encounter a prompt (an event, meeting, clinic, or poster). They remove a common friction point — typing a web address — and are especially useful for reaching multilingual or mobile-first audiences because they open the survey directly on the participant's device. For teams using Hearo, a single multilingual survey linked via QR code means you don't need separate printed forms in every language; participants see the survey in the language they prefer, and administrators receive translated responses back for review.
FAQ
Do participants need a special app to scan a QR-code survey?
No. Most modern smartphone cameras can scan QR codes directly. If a device doesn't support native scanning, a free QR-scanner app can be used. The code simply opens the survey URL in the phone's browser — no account is required.
What if someone can't scan the QR code?
Always provide an alternative: a short, easy-to-type URL, a QR-friendly NFC tag, or a printed phone number/shortcode for SMS. Also include a brief instruction line so people know what to do if scanning fails.
Can a QR code send people to a survey in a specific language?
Yes. You can use a URL parameter or separate short links encoded in different QR codes to open the survey with a language pre-selected. Alternatively, multilingual platforms can auto-detect a participant's device language and offer language options on the landing page.
Will I know who scanned the QR code and completed the survey?
QR codes themselves are just links. You can use distinct links for different locations or campaigns to track where responses came from, but identifying individuals requires adding optional contact fields in the survey. Be transparent about any tracking and follow privacy rules for your organisation.
