When a customer goes to a restaurant or a shop. They usually ask owner the WIFI name and password. After that, they have to enter long WIFI password which could contain uppercase, special character and is very hard to remember and type. It is very boring and time consuming job. Smarter approach is that owner will create a WIFI QR Code and stick to restaurant's wall or menu. And then customer will scan this QR Code to access WIFI network automatically without entering anything. They can use Barcode QR Code generator For Google Docs for creating QR Code WIFI very easily.
