Camera-Based WiFi Network Onboarding
Enter your network name and password once, and guests scan instead of typing a password on a phone keyboard. The generated code encodes your network's security type (WPA/WPA2, WEP, or none) directly, so most modern phone cameras join the network automatically after scanning — no app needed on iOS 11+ or Android 10+. Older Android versions may open a QR scanner app instead of joining directly; if you expect older devices, pair this with the network name printed alongside the code as a fallback. Changing your WiFi password later means generating and reprinting a new code — this type is static by design, since WiFi credentials aren't something you want stored on a server.
MeCard and ZXing WiFi String Architecture
WiFi QR codes follow the standard ZXing protocol syntax: WIFI:S:<SSID>;T:<WPA|WEP|nopass>;P:<password>;H:<true|false>;;. Because the credentials reside entirely in the visual pattern, no cloud intermediary stores your private home or office access keys.
When users scan the code with their default camera lens, the operating system's networking daemon catches the intent, validates the SSID broadcast, and performs the WPA 4-way handshake automatically without requiring user clipboard copy-paste.
Operating System Support Matrix
Default Camera app detects the SSID payload immediately and presents a system banner stating "Join ‘Network_Name’ Network?". Tapping connects the device directly without prompting for password entry.
Google Camera and Quick Settings Barcode Tile recognize the ZXing string and display a "Connect to Network" chip. Tapping executes the supplicant connection seamlessly.
Frequently Asked Questions
Is my WiFi password transmitted to your server?
No. The WiFi QR code is generated 100% locally within your browser. Your network SSID and password are never sent across the internet.
Will this work if my router uses WPA3-Personal?
Yes. Mobile operating systems handle WPA3 authentication gracefully using the standard WPA protocol flag encoded in the code.
