Cafés, restaurants, guesthouses — and any home with frequent visitors — share the same chore: repeating the Wi-Fi password. A Wi-Fi QR code fixes it with a single scan.
What you need
- Network name (SSID) — the name people see when searching for Wi-Fi. It must match exactly.
- Password — also exact; capitalization matters.
- Security type — most modern routers use WPA/WPA2. If unsure, pick that.
Creating the code
Open the Wi-Fi QR generator, fill in the three fields, and download. Your Wi-Fi details are processed inside your browser only — never stored on any server.
Test before you post it
Scan with both an iPhone and an Android if you can, since the two systems handle Wi-Fi QR codes slightly differently. iPhones scan from the normal camera since iOS 11; recent Androids scan from the camera or Wi-Fi settings.
Common mistakes
- Changing the Wi-Fi password and forgetting to make a new code — static QR codes can't be edited, only regenerated.
- One wrong character in the SSID, so phones can't find the network.
- Posting the code where glare hits it, making it hard for cameras to read.
Print it at least 3×3 cm, place it at eye level on tables or the counter, and your guests will thank you.
