People these days expect to have a Wi-Fi connection in every mall, hotel and restaurant. Now, most of the businesses offer Wi-Fi, they are not as much as effective at sharing the credentials. Even many restaurants print the Wi-Fi username and password on walls as QR code.
You can now make Wi-Fi QR codes to share the Wi-Fi credentials with the clients. They can now scan the QR code for getting Wi-Fi credentials and connect to Wi-Fi.
Scan easily and get access to Wi-Fi.
