Sorry, Android only to produce the QR Code. But Apple users can scan it too.
A quick way to share a WiFi network and its password is using a QR code like the one shown below.
To display the QR code, navigate these steps:
1. Touch "Settings"
2. Touch "Network & internet"
3. Touch the network you want to share then touch "Share"
That network might be located in "Saved networks", if you not near to it.
Next week I'll cover how you scan it from Android and Apple smartphones.
