Wi-Fi QR Code

Scan to join Wi-Fi

Enter the network name, password and security type and you get a QR code in the standard Wi-Fi format (WIFI:T:WPA;S:name;P:password;;). The built-in camera on iPhone (iOS 11+) and Android (10+) shows a “Join network” prompt — no typing needed.

Things to check

• Exact name and password, including upper/lower case — copy them from the router label or admin page. Spaces count.
• Different 2.4 GHz and 5 GHz names? Use the one guests should join, or make two codes.
• Security — almost all modern routers use WPA2/WPA3. Leave it as is if unsure.
• Special characters such as ; , : \ " in the name or password are escaped correctly.

Print a sign

“Sign PNG” is a portrait card (1200×1600 px, 3:4). Printed on A6 (105×148 mm) it leaves a small margin at the top and bottom. Print it for the counter or tables, or slip it into an acrylic stand. To hide the password text, turn off “Also show the password” — the QR code still works.

Security

The password is turned into a QR code in this browser and never transmitted. Anyone who scans the code can join, so for businesses use a separate guest network isolated from your internal devices.
