What you get with the Wi-Fi QR Code

Join in one scan

Works with the built-in camera on iPhone and most Android phones.

Printable Wi-Fi card

A ready-made sign with the code, network name and, if you like, the password.

PNG and SVG

PNG for screens and documents, SVG for sharp printing at any size.

Password stays private

The code is made in your browser. Nothing is uploaded or stored.

How to use the Wi-Fi QR Code

  1. Type your network name (SSID) exactly as it appears on your phone, including capitals.
  2. Enter the password and choose the security type (WPA for almost every home and office router).
  3. Test-scan the preview, then download PNG or SVG, or click Print Wi-Fi card to print a sign for the wall or table.

Questions

How do I scan a Wi-Fi QR code?

Open the camera app on an iPhone or Android phone and point it at the code, then tap the Wi-Fi notification. On some Android phones, use Google Lens or the QR scanner in the Wi-Fi settings.

Is my Wi-Fi password sent to DocNova?

No. The QR code is created in your browser and the password is stored only inside the code itself. Nothing is uploaded or saved.

Which security type should I choose?

Choose WPA for WPA, WPA2 and WPA3 networks, which covers almost every router made in the last 15 years. Choose WEP only for very old routers, and "nopass" for open networks without a password.

Does the code stop working if I change the password?

Yes. The password is inside the code, so after changing your Wi-Fi password, make a new code and replace the printed one.

Can I hide the password on the printed card?

Yes. Untick "Show the password on the printed Wi-Fi card". Guests can still connect by scanning, but the password is not written on the card.

Where a Wi-Fi QR code helps

A Wi-Fi QR code saves guests from reading out long passwords and typing them wrongly. It is perfect for cafés and restaurants, holiday rentals and Airbnb listings, offices and meeting rooms, waiting rooms, events, and simply the fridge door at home. People scan it, tap Join, and they are online in a few seconds.

The code follows the standard Wi-Fi QR format (WIFI:T:WPA;S:network;P:password;;) that iPhone and Android cameras understand without any app. Because the details live inside the code, it works offline and never expires.

Tips for a code that always works

  • Copy the network name exactly. Names are case-sensitive: "HomeWiFi" and "homewifi" are different networks. Check spaces too.
  • Test before printing. Scan the preview with two different phones, ideally one iPhone and one Android.
  • Print it big enough. At least 3 cm (about 1.2 inches) wide for a table card, bigger for a wall sign people scan from a distance.
  • Use a guest network. If your router supports it, give visitors a separate guest network so they never get access to your own devices.
  • Keep the contrast high. A dark code on a white background scans best. Avoid light colours on dark backgrounds.

Common mistakes

  • Wrong security type. Choose WPA for WPA2 and WPA3 networks. Choosing WEP or "nopass" for a password-protected network stops phones connecting.
  • Forgetting to replace the sign. After you change the password, old printed codes stop working. Make a new one straight away.
  • Hidden networks. If your router does not broadcast its name, tick "Hidden network", otherwise some phones will not find it.
  • Posting the code online. Anyone who sees a photo of the code can join your network. Keep it inside your premises.

Examples

Holiday rental: print the Wi-Fi card, put it in a frame by the door, and add the same code to your welcome guide PDF.

Café: print small table cards with the guest network code and untick "Show the password" so it cannot be copied from the card.

Office meeting room: add the code to the room sign next to a QR code that links to the booking page.

Install DocNova
