# QR complaint box

People who use your restrooms, elevators, lobbies or parking areas often notice problems before your staff do. With the MintCheck complaint box, they scan a QR code next to the asset, describe the problem and add up to 3 photos, with no account and no app. The complaint arrives in MintCheck, and the site's administrators get an email.

## How it works

1. **Turn on the complaint box.** Switch it on for an asset, add a short guide message for visitors, and print the complaint QR code.
2. **Visitors report the problem.** The form opens in the visitor's phone language. They describe the issue, attach up to 3 photos and can leave an email or phone number to hear back.
3. **Handle and resolve it.** Move each complaint from Received to In progress to Resolved, adding notes along the way. Administrators get an email for new complaints and for every status change.

## Good to know

- Visitors don't need to sign in or install anything.
- Anonymous by default, with optional email verification by a 6-digit code to cut down on spam.
- The same QR code can also collect improvement ideas.
- Unresolved complaints are highlighted on the site dashboard.

## Questions

### Do visitors need to install anything?

No. They scan the complaint QR code with the phone camera, and a simple form opens in their phone's language.

### How can I stop fake or repeated complaints?

Turn on email verification. The visitor must enter an email address and the 6-digit code MintCheck sends, which is valid for 10 minutes, before they can submit.

### How do I know when a complaint arrives?

MintCheck emails the site's administrators and the super admin when a new complaint arrives and whenever its status changes. The site dashboard also shows how many are unresolved.
