Every user can prompt for tips on their iPad POS Platform. The prompt comes in two forms – a line on the physical receipt for the customer to add a tip and then sign OR a prompt on the Customer Facing Display for adding a tip and signing on screen.
For this function, several options have to be visited on the Management Console:
Settings-->Receipt-->Print Credit Card receipts must be set on "Signature" or "Prompt". Enable Signature only if using Customer Display System.
On the CDS, when the customer pays with a Credit Card, "Select Tip Amount" will display and the customer can choose between the percentages shown or choose Other to enter the tip amount manually.
