How WiFi QR CodesActually Work
WiFi QR codes encode network credentials in a standardized string format that iOS and Android can read and interpret automatically.
The WIFI: String Format
WiFi QR codes use a standardized string format defined by the ZXing project. The format encodes all necessary network information in a simple, machine-readable string.
