# Tamper-resistant QR codes for parking payments

> Parking meters are the top target for QR sticker fraud. Kizmo codes show drivers a verified check screen, tell them what to look for, and alert you when a meter's code stops getting scans.

Scam stickers on parking meters send drivers to cloned payment pages. The FBI and many city governments have warned about it. You cannot stop someone sticking a label on a meter, but you can make the genuine code recognisable and find out quickly when one is covered.

## Steps

1. Create one dynamic code per meter or zone and set the placement (for example 'Meter 12, Elm St').
2. Turn on the verified check screen: drivers see your organisation's name and the payment site before continuing.
3. Print the human-readable code and 'Pay only at yourdomain.com' next to the QR.
4. Leave tamper monitoring on. If a meter that normally gets scans goes silent, you get an alert naming it.

**Recommended size:** 40-60 mm, at eye level, behind a clear protective cover where possible.

## Tips

- Print the payment domain in large text so drivers can compare it with the page they land on.
- Use a tamper-evident laminate or frame that makes an added sticker obvious.
- Publish your verify link (kizmo.io/verify/your-code) on signage and your website.

## Common mistakes

- Using a generic short link that looks like any other short link and trains drivers to trust unknown domains.
- Relying on a code that stops working when a subscription ends: a dead official code pushes drivers toward the fake one.

## Frequently asked questions

### How does Kizmo detect a covered code?

Each monitored code learns its normal scan rate by weekday. When a code that usually gets scanned records none over a day, the probability of that happening by chance is tiny, so we alert you with the placement name.

### Can Kizmo stop someone placing a sticker?

No software can prevent a physical sticker. Kizmo shortens the time a fake code goes unnoticed, and helps drivers spot a genuine code before they pay.
