A QR code solves the problem a terminal cannot: it puts the survey on the customer's own phone, which means the answer can be identified, replied to and followed up. It also introduces a new failure, which is that scanning is voluntary work. Whether anybody does it is decided by where the code sits, what the label next to it promises, and how fast the thing it opens actually is.
Where the code sits
On the receipt, the table, the bag, the invoice or the counter, at the moment there is a pause. A code on a poster by the exit is scanned by nobody, because leaving is the moment people are least willing to stop. The best-performing placements are the ones where the customer is already waiting for something, which is why receipts and tables outperform walls consistently.
The label does the persuading
A bare code gets ignored. Say what it is, how long it takes and what happens to the answer: thirty seconds, one question, read by the manager. Promising a reply raises scans and obliges you to deliver one, so only promise it if somebody is genuinely working the list within a couple of days.
What it opens matters more than the code
The page has to load in a second on a bad connection, show one question above the fold, and not ask anybody to sign in or accept anything before answering. Every extra step between the scan and the first tap costs a share of the people who scanned, and a survey that opens on a cookie banner is a survey nobody finished.
Why the identifiable answer is worth the extra effort
A scan can carry the site, the till, the table or the order, so the answer arrives attached to something real. That is what a terminal press cannot give you, and it is what makes the follow-up possible: you know which visit went wrong and often who to call, which is the whole difference between a score and a piece of work.
Questions people ask about survey qr code
What scan rate should we expect?
It varies hugely by placement, so measure your own for a fortnight before planning around it. Receipts and tables beat posters by a wide margin.
Should the survey ask for contact details?
Only if you will reply. Ask at the end, after the score, and make it optional so the answer is already recorded either way.
Does the code need to be dynamic?
If you want to know which site, till or order it came from, yes. A single static code across ten locations tells you the average of ten places and little else.
Is a QR code better than a kiosk?
It is different. The kiosk gets volume and anonymity; the code gets fewer answers you can actually reply to. Most businesses with sites end up running both.
