can a surcharge be applied to both credit and debit cards, and how can I implement a custom surcharge based on card type and purchased product in an app? For example, if a customer purchases a product for $10, can I add a 3.20% surcharge for credit cards, and then have Clover add an additional 0.30% surcharge at checkout, making the total surcharge 3.50%?
And also is it possible to increase surcharge rate above 4.0% in clover?
