How we verify this guide
Before this page is included in the public guide directory, its examples are compared with the payload produced by the linked QRFlow generator and with the export and scan-readiness controls available in the current build. Camera, lighting, paper, print size, and destination apps can still change the result, so important print runs should always be tested on the final material and real devices.
A WiFi QR code usually encodes a string like WIFI:T:WPA;S:MySSID;P:MyPass;H:false;;. Phones read it and offer to join the network.
Why WiFi QR codes fail # SSID/password mismatch (case-sensitive) Special characters that need escaping Hidden SSID behavior differences Low contrast / too small for print Generate a new one: WiFi QR code generator . For details: WiFi format guide .
