1What should the QR open?
Type it exactly as your phone shows it, including capitals and spaces.
Mobile or landline. For a landline, type the STD code without the 0, for example 22 2345 6789.
Paste a map link (a share link from the map app works too), or type latitude, longitude.

Scan the code with two different phones before you print copies. The SVG has the bare QR code, which stays sharp at any size.
Stop reading the Wi-Fi password out loud
If you run a cafe, a salon, a coaching centre, a PG or a small office, you have probably spelled out the Wi-Fi password many times a day: "capital S, then 2026, then the at sign…". A Wi-Fi QR code ends that. The guest opens the camera, points it at the poster, taps the prompt and is online. Nobody has to type anything, so there are no typing mistakes either.
The code holds three things: your network name, the password and the security type. It is written in the standard WIFI: format that phone cameras and scanner apps understand, for example WIFI:T:WPA;S:Sharma Cafe Guest;P:chai@2026;H:false;;. The tool builds this text for you and escapes special characters such as ; and : inside the password, which is where hand-made codes often break.
Where to put a Wi-Fi QR code
- Cafes and restaurants: a table tent on every table, or a small sticker on the menu card. Choose the "tent" design, print it on A4 and fold it along the dashed line.
- Shops and showrooms: next to the billing counter, so customers can check product videos or pay online with a steady connection.
- PGs and hostels: one poster per floor, especially if each floor has its own router. Make a separate code for each network name.
- Offices and co-working spaces: in the reception and meeting rooms, for the visitor network only.
- Homes: on the fridge or inside a cupboard door, so visiting relatives can connect without hunting for the router sticker.
Use a guest network, not your main one
A Wi-Fi QR code is the password in printed form. Anyone who scans it with a scanner app can read the password, and anyone who photographs the poster can share it. So the safest setup for a business is a separate guest network, which most modern routers can create from their settings page:
- Create a guest network with its own name and password, such as "Sharma Cafe Guest".
- Keep your billing computer, CCTV recorder and printers on the main network only.
- Make the QR code for the guest network.
- Change the guest password now and then, and print a new code each time.
If you would rather not print the password in words, turn off "Show password on the poster". The code still works; the poster will simply not show the password under it.
Which phones scan a Wi-Fi QR code?
On iPhones, the built-in Camera app reads QR codes from iOS 11 onwards and shows a prompt to join the network. On Android, it depends on the phone: many camera apps read QR codes directly, Google Lens can read them, and on recent versions the Wi-Fi settings screen has a QR option. Android 10 and later can also show your current network as a QR code, which is handy for a quick share, though menu names differ between brands (see Android Help). Very old phones may need a scanner app, so keep the network name and password printed on the poster as a fallback.
Before you print
- Check the network name letter by letter. It is case-sensitive, and a single extra space breaks the code.
- Pick WPA / WPA2 / WPA3 for almost all routers. WEP is only for very old ones.
- Forget the network on your own phone, then scan the printed code to join it fresh. That is the only real test.
- Laminate posters that will sit on tables, so tea and water spills do not smudge the code.

Frequently asked questions
Which phones can scan a Wi-Fi QR code?
iPhones running iOS 11 or later can read QR codes from the built-in Camera app and offer to join the network. Most recent Android phones can scan them with the camera app, Google Lens or the QR option in Wi-Fi settings; the exact menu name depends on the phone brand. Older phones may need a scanner app.
Does the QR code still work if I change my Wi-Fi password?
No. The password is stored inside the code, so a new password needs a new code. Make a fresh one here and replace every printed copy, or guests will see a wrong-password error.
Can people see my Wi-Fi password from the QR code?
Yes, anyone who scans it with a scanner app can read the password. That is why it is best used for a separate guest network. If you do not want the password printed under the code as well, turn off 'Show password on the poster'.
What if my network is hidden?
Tick 'Hidden network'. The code then tells the phone that the network does not broadcast its name, so it searches for it directly. Type the network name exactly, because hidden networks cannot be picked from a list.
Which security type should I choose?
Choose WPA / WPA2 / WPA3 for almost every modern router; it is the setting most home and office routers use. Pick WEP only for very old routers, and None only for open networks without a password.
