Wifi Code allows you to generate a QR code for your Wifi network.

You want to share your wifi network:

1) Enter the name of your network (SSID)
2) Enter your network password (if you have one)
3) Select your type of network security (WPA default, WEP)
4) Select whether your network is hidden or not
5) Print and save the QRCode generated by the application

This is by far the easiest and most convenient way to connect to a Wifi network.

You want to access a wifi network:

1) Open your camera or scan application
2) Scan the QRcode
3) Connect to the wifi network
