# Feedback QR codes — how they work

> A feedback QR code points at a short form or a prefilled email. Response rate is governed almost entirely by two things — how close the code is to the moment of experience, and how few fields the form has. One question beats five, every time.

## What to point at

| Destination | Good for | Watch out for |
|---|---|---|
| A hosted form (Google Forms, Typeform, your own) | structured data | slow to load; consent wording |
| A prefilled `mailto:` | written detail, zero setup | you get an email address with it |
| A one-tap rating page | volume | shallow signal |
| A public review site | reputation | you cannot filter, and must not |

For most businesses the honest combination is a private feedback code *and* a public
[Google review code](/google-review-qr-code) side by side, clearly labelled. The
customer chooses. That is not review gating, because you are not filtering.

## Every field costs you responses

Feedback forms fail by asking too much. The pattern that works:

1. One question on the first screen. A rating, or "how did it go?".
2. Everything else optional, on the *next* screen, after they have committed.
3. No login. No email required. No captcha.
4. Under two seconds to load on cellular.

If you need to reach the person again, ask for contact details *after* the rating, and
explain why.

## Placement beats copy

- **Receipt or bill folder**: the highest-yield location in hospitality.
- **Delivery packaging**: high, because the experience just completed.
- **Hotel room, on the desk**: works for stays.
- **Exit door at eye level**: works when there is no receipt.
- **Entrance**: does not work. The experience has not happened yet.

## GDPR and equivalents

If the form collects anything identifying — name, email, room number, order id — you
need a lawful basis and a privacy notice at the point of collection, not buried in a
footer. State what you collect, why, how long you keep it, and how to have it deleted.
An anonymous rating with no identifiers avoids most of this entirely, which is another
reason to keep the first screen to one question.

## FAQ

### How many questions should a feedback form have?
One on the first screen. Everything else optional afterwards. Each additional required field measurably reduces completion, and a five-field form collects less usable data than a one-field one.

### Where should I put a feedback QR code?
On the receipt, the bill folder, the delivery packaging or at the exit — after the experience. Codes at the entrance do not get scanned because there is nothing to give feedback on yet.

### Can I show a feedback code and a Google review code together?
Yes, as long as both are visible and the customer chooses. That is not review gating. Filtering customers and only showing the review code to happy ones is prohibited.

### Do I need a privacy notice?
If the form collects anything identifying, yes — at the point of collection. An anonymous single-question rating avoids most of this.
