Optionally you can add a customer diplay connected to Cashy-POS on the iPad. It can run on an old iPhone (min. iPhone 3GS) and will display all sales while you are registering them to the customer.

If no sales registering is in progress, it can display a screensaver picture or f.ex. an advertising movie.

In order to use this option, you need a dedicated application (Cashy-Display) running on a device connected to the same WiFi-network as the iPad.

You can find the customer display application for Cashy-POS in apples AppStore using this LINK
