Customers will stay longer if they can enjoy a coffee in your bistro while checking their mails or going online with the help of your WLAN hotspot.
They can login to the hotspot automatically via e-mail or SMS - no staff required. Your customers will recognize the guest network as an advantage over your competitors. It is of course completely separated from the rest of your store's network, so your internal data remains secure.
While your customers are online, you as the shop owner can distribute your latest advertising at an interval of your choice.
