Wi‑Fi QR Guide for Cafes and Restaurants

Last updated: December 11, 2025 — See all guides at /guides/

This guide helps cafes and restaurants deploy Wi‑Fi QR codes that work reliably without constant staff support.

1) Set up the right guest network

Use a guest SSID

Create a dedicated guest SSID to isolate visitors from internal systems (POS, printers, staff devices).

Pick WPA2/WPA3

Use WPA2 or WPA3. Avoid open networks unless you must use a captive portal.

Set a rotation cadence

Busy cafes: rotate weekly.
Restaurants: rotate monthly unless abuse is common.

2) Generate and test the QR

Enter the exact SSID and password (case-sensitive).
Choose WPA/WPA2/WPA3; error correction M or Q.
Export at 800–1200 px for print; 300–500 px for screens.
Test with one iOS and one Android device in real lighting.

3) Placement strategy

Table tents at each table or counter are ideal.
Place a larger poster near the entrance or pickup counter.
Avoid glossy lamination and reflective frames.

4) Use the printable templates

Use the table tent template for fast deployment:

Download table tent SVG

5) Staff workflow

Store the QR PNG in a shared folder with the date in the filename.
Keep a printed spare at the counter.
Replace old table tents immediately after rotation.

6) Common problems and fixes

Guests can scan but can’t join: check security type and password accuracy.
Slow scans: increase QR size and contrast; avoid glare.
Frequent “What’s the Wi‑Fi?” questions: add signage at entrance and pickup counter.
