Wifi QR Plaque Template
A flat wall plate with two mounting holes and a raised QR code that lets visitors join your wifi by pointing a camera at it. No more spelling out a password across the room.
What the code stores
A wifi QR code does not link to a web page. It holds the network name, the security type and the password in a standard text format that phone cameras recognise, along the lines of WIFI:T:WPA;S:NetworkName;P:Password;;. When a guest scans it, the phone offers to join the network, and nothing has to be typed.
Because the password sits inside the code, anyone who scans the plaque can also read it. Set the plaque up for a guest network, not for the one your computers and cameras use.
Approximate measurements
A typical wifi code is about 33 modules per side, because the network name and password both go into the code. The figures below use the medium setting (2.3 mm modules) and should be read as approximate.
| Feature | Approximate value |
|---|---|
| QR code width (about 33 modules) | 75.9 mm |
| Plaque width × height | 85.9 × 93.9 mm |
| Plaque height with raised text | about 100.9 mm |
| Thickness | 4.4 mm (3.2 mm base + 1.2 mm relief) |
| Mounting holes | 2 holes, 3.6 mm diameter, along the top edge |
A longer network name or password adds modules, and each extra four modules grows the plaque by roughly 9 mm in the medium setting. Choose sensible lengths, but do not weaken a password just to save a few millimetres.
Who it is for
- Holiday rentals and guest rooms, where visitors ask for the wifi within minutes of arriving.
- Waiting rooms, salons and small clinics that offer a guest network to clients.
- Meeting rooms and shared offices, where visitors turn up with laptops and phones.
- Homes with regular visitors: a plaque by the front door or in the living room saves reading out a long password.
Tips for using it
- Create a separate guest network first and put that one in the code; keep your main network private.
- Hang the plaque at eye level near where people sit, and thread screws or nails through the two holes so the heads are wider than the 3.6 mm openings.
- Add the network name as raised text so people who cannot scan can still type it in by hand.
- Test on both an iPhone and an Android phone before you mount it. If a print will not read, use the troubleshooting checklist.
- Write down the date you printed it, so you remember to replace the plaque after a password change.
Frequently asked questions
Is it safe to put my wifi password in a QR code?
The password is stored in the code itself, so anyone who can scan the plaque can read it. That is fine for a guest network that you are happy to share, but do not use it for your main network.
What happens when I change the wifi password?
The old plaque keeps offering the old password, so it stops working. Print a new one, and think of the plaque as something that is replaced whenever the password changes.
How do I hang it?
Use the two 3.6 mm holes at the top with small screws or nails whose heads are wider than the holes. You can also lean the flat plaque against a wall or shelf.
Will every phone read it?
Recent iPhone and Android cameras recognise wifi codes and offer to join the network. On an older phone, a free QR scanner app does the same job.
