How Do Smartphones Connect via Wi-Fi QR Codes?
Standardized WIFI: URI
The standardized schema encodes network credentials into a clean URI recognized natively by camera optical scanners without requiring any third-party app.
Level H Error Correction
Level H error correction reconstructs up to 30% of corrupted matrix data, ensuring instantaneous scanability even with the center logo emblem.
Zero Credential Transmission
Credentials are rendered in pure client-side JavaScript canvas memory; passwords never traverse backend network cables.

SSID or password mismatch: trailing spaces, capitalization differences, or special characters.
Inspect the label on your physical router to verify the factory SSID and WPA/WPA2 passphrase.

The 2.4 GHz band provides greater physical wall penetration and universal legacy compatibility.
