Your terminal is not pre-configured to allow for Surcharging. If you would like the Surcharge functionality enabled on your terminal please contact the terminal Helpdesk.
The Surcharge functionality would commonly be used within the leisure & service industries in order to add a surcharge of a set amount or set percentage rate to the total of the bill automatically. For example you could automatically apply a surcharge of 10% to all transactions over £10.00, and a £1.00 surcharge to all transactions of £10.00 and less.
You can discuss your specific requirements by contacting the terminal Helpdesk.
