What Are WiFi QR Codes?
"What's the WiFi password?" is the most repeated question in every café, waiting room, and guest bedroom. A WiFi QR code retires it: guests point a camera at a framed card and they're connected, with nobody spelling out "capital B, underscore, seven" across the room. If you just want to skip ahead and make one for your venue, the WiFi QR code generator takes about thirty seconds.
How WiFi QR Codes Work
The Technology
WiFi QR codes encode:
- Network name (SSID)
- Password
- Encryption type (WPA/WPA2/WEP)
- Hidden network flag
The Format
Standard WiFi QR format:
WIFI:T:WPA;S:NetworkName;P:Password;;Device Compatibility
- iOS 11+ (native camera)
- Android 10+ (native camera)
- Older devices: QR scanner app

Set it up this afternoon
The full checklist fits in an hour: enable your router's guest network, generate the code, print two copies (one laminated for the wall, one spare), and scan it yourself with both an iPhone and an Android before posting it. From then on, the only maintenance is regenerating the code when you rotate the password.
