WiFi QR Codes: How They Work and Who Can Scan Them
A WiFi QR code encodes your network credentials in a standard format that smartphones can scan to connect automatically. No typing. No mistakes.
How a WiFi QR code works
WiFi QR codes use the WIFI: URI scheme to encode your network name (SSID), password, and security type in a scannable format. When your phone camera reads the code, it decodes the credentials and prompts you to join the network instantly.
Which devices support WiFi QR codes
iPhone iOS 13+ (September 2019) and Android 10+ (2019) can scan WiFi QR codes natively with the built-in camera app. No third-party app needed. Older devices can still connect — they just read the printed SSID and password manually.
How WifiWhale generates the QR code
WifiWhale generates your QR code using the standard WIFI: format and embeds it at 300 DPI in your PDF. The QR code is tested to work on both iOS and Android camera apps without any additional software.
Tips for a scannable QR code
Print at 100% scale (never scaled down), ensure the QR has sufficient quiet zone (white border) around it, and laminate with a matte finish rather than glossy to prevent light glare.
