Do Wi-Fi QR codes work on all phones?

They work on iPhones with iOS 11 or later and on most Android phones through the camera or Google Lens. Very old phones may need a QR scanner app.

Is it safe to print my Wi-Fi password as a QR code?

It is as safe as writing the password on a card. Use a separate guest network for customers so they can’t reach your billing systems.

What if my network is hidden?

Tick the hidden option when you make the code. The phone then joins the network even though it isn’t shown in the Wi-Fi list.

How to share your Wi-Fi with a QR code

Short answer

A Wi-Fi QR code stores your network name, password and security type, so customers join by pointing their phone camera at it, without typing. Make one free with a Wi-Fi QR generator, print it for each table, and use a separate guest network so customers never get access to your billing systems.

How does a Wi-Fi QR code work?

The code contains a short line of text in a standard format (WIFI:T:WPA;S:network;P:password;;). iPhones from iOS 11 and most Android phones read it with the built-in camera and offer to join the network. Nothing needs to be installed.

How to make one

Check your network name exactly as phones show it, including capital letters.
Open a Wi-Fi QR code generator, such as Oyelo’s free one, and type the network name and password.
Choose the security type: WPA/WPA2/WPA3 for almost every modern router.
Download the card, test it with one Android phone and one iPhone, then print copies.

Keep your business network safe

Create a guest network on your router for customers, separate from the one your billing and POS use.
Anyone who can scan the code can join, so don’t use your main network’s password.
If you change the password, the printed code stops working: make and print a new one.

Can the same QR do more than Wi-Fi?

A plain Wi-Fi QR only joins the network. A table QR page such as Oyelo QR shows the Wi-Fi with a copy button and its own Wi-Fi QR, plus your menu, today’s offer, a “Need help?” button and feedback with your Google review link. Because the printed code opens a page, you can change the Wi-Fi password without reprinting.
