    Customer Facing Display

    The iPP320 and iPP350 also act as a customer facing display to show transaction details as a cashier uses the register. Learn below about the customer facing display’s features and how to toggle the display off or on.

    Display Features

    View below what your customer sees on the iPP320 or iPP350 as the cashier moves through a sale.

    The reader shows the last item added or edited along with its quantity and modifiers.

    ‘Item Removed’ indicates the cashier deleted that item from the sale.

    When the cashier tenders a sale to Credit, customers see their total and a message to swipe/tap/insert a card.

    For non-credit tenders, the reader displays discounts, tax, and the total due.
    This screen also appears for returns and saved checks.

    If the cashier selects Split Tender, each payment’s total appears as the cashier tenders it.

    Display Settings

    The customer facing display feature is enabled by default, but you can toggle it off or back on as desired.

    1. In BackOffice, click 'Settings' and select 'General'.
    2. To disable the display, uncheck the 'Enable' box and click 'Save'.

      To enable the display, re-check the box.
