A WiFi QR Code stores the network name, the password and the security type inside the code itself. When scanned with a phone camera, the device recognizes the data and offers to connect automatically, with no need to open settings or type anything. It is handy for receptions, cafes, clinics and anywhere that offers WiFi to visitors.
Frequently asked questions
How does the automatic connection work?
Most modern phones recognize the WiFi QR Code standard right in the native camera app and show a button to connect, with no extra app required.
Does it work on any phone?
It works on the vast majority of recent Android phones and iPhones. On older models you may need a separate QR Code reader.
Is the password exposed to anyone who sees the QR Code?
The password is encoded inside the image, not displayed as text. Even so, treat the QR Code the way you would treat the written password: avoid leaving it in public if the network is restricted.
Which security type should I choose?
Use WPA/WPA2 for most current networks, WEP only if your router is old, and No password only for open networks.
