Wi-Fi QR code: guests connect without typing a password

Instead of “what is the Wi-Fi password?” – a sign on the table. A guest points the camera and the phone joins the network. How to make such a code in a minute and where to put it.

A Wi-Fi QR code with the caption Guest Wi-Fi in the BOMBA DESIGN generator — **Wi-Fi QR code:** network name, password and security type – ready for print.

Cafes, salons, coworking spaces, hotels, waiting rooms – guests everywhere ask for the Wi-Fi password. Staff spell it out, guests mistype a letter, and it all starts again. A QR code removes that conversation: the phone camera reads the network name and password and offers to connect.

The code holds no link to a website or service. The network details are written into the code itself, so it works offline, without a subscription and without an expiry date.

Key points

A Wi-Fi QR code contains the network name, the password and the security type.
Cameras on modern iPhones and Android phones read it without extra apps.
Changed the password? Make and print a new code – the old one will no longer connect.

BasicsWhat a Wi-Fi QR code contains

Field	What to enter
Network name (SSID)	Exactly as it appears in the list of networks: upper and lower case, spaces and underscores
Password	The guest network password. Upper and lower case matter
Security	WPA / WPA2 / WPA3 – for almost all modern routers. WEP – for very old ones. No password – for an open network

The security type is shown in the router settings. If you are not sure, keep WPA: the vast majority of networks use it.

How-toHow to make a Wi-Fi QR code: 4 steps

Open the generatorGo to QR code with logo and choose the Wi-Fi tab.
Enter the network detailsNetwork name, password and security type. The code appears at once.
Add a caption and logoA ready caption “Guest Wi-Fi” or your own text up to 40 characters. A logo in the centre is optional.
Check and downloadThe tool checks that the code scans. Download PNG, SVG, PDF or EPS and point your own phone at it.

PlacementWhere to put a Wi-Fi QR code

Place	How to present it
Cafe table	A table tent or a sticker on the napkin holder
Reception, checkout	A sign next to the card terminal – everyone looks there
Hotel room	A card by the bed or on the door
Waiting area	A poster on the wall at eye level
Menu	A separate block on the first or last page

Keep the network name and password as text next to the code. Some people scan, others find it easier to type – for example on a laptop.

PrintWhat size to print the code

For a table sign 3–5 cm is enough: guests scan from arm’s length. A wall poster scanned from a few metres needs a bigger code – roughly 1 cm for every 10 cm of distance.

The tool shows the minimum print size under each code. Vector SVG, PDF and EPS stay sharp at any size, so send those to the print shop.

SecurityKeep the guest network separate

Anyone who takes a photo of the code gets the password. That is why guests are better off on a separate guest network: most routers can switch one on in the settings. The till, accounting computers and security cameras stay on the work network, which guests never reach.

If you change the password from time to time, plan how to replace the sign quickly: a sticker or an insert in a frame is easier to swap than a code printed on a menu.

HonestlyThe tool makes the code. We design the sign in your brand style

The generator gives you the QR code with a caption. A table sign, a door sticker or a menu page should look like part of your place: brand colours, typeface, logo.

We design print materials in your brand identity: print design. No logo yet? Start with a logo.

A guest who got online quickly is more likely to tag your place in a story. Put your Instagram handle next to the code.
