# QR codes for cafés

> For a café the highest-value QR code is not the menu — it is the WiFi code at the counter and a UPI, PIX or local payment code sized for the counter distance. Both remove a repeated interaction from every shift.

## What actually gets scanned

1. **WiFi** — the most-asked question in any café. A printed card at the counter and on each
   table ends it. Use a guest network separated from your till system.
2. **Payment** — a counter code for [UPI](/upi-qr-code), [PIX](/pix-qr-code) or your local
   rail, at least **4 cm** for a 40 cm counter distance.
3. **Loyalty** — a code replacing the punch card.
4. **Google review** — on the receipt or the cup sleeve.

## Counter payment codes: check them daily

The dominant fraud is physical — someone pastes their own payment code over yours. Print the
payee name large enough that a customer notices when their app shows a different one, and
look at the standee at the start of every shift. It takes five seconds and it is the only
defence that works.

## WiFi card design

- Print it as a card at the counter and on tables, not in the window.
- Include the network name in text as a fallback.
- Use WPA (which covers WPA3 — the format has no separate WPA3 value).
- If your network has a captive portal, say so, or people will think the code is broken.

Our [WiFi card tool](/wifi-card) prints an A6 card or table tent with the instructions
already laid out.

## The cup sleeve

A code on a takeaway sleeve is scanned somewhere else entirely — on a train, at a desk.
Point it at something worth reading later: the roastery story, a subscription, the loyalty
signup. Not the menu they have already ordered from.
