Credit Card Charges
Under the current Credit Card System, the Retailer is charged a percentage by the payment processor. Most high street retailers now pass these charges on to the customer.
Please provide a facility where certain types of credit cards can have a percentage charge added to the customer invoice.
I don't think online payment solutions pass this information to integrated software. But I am keeping this idea for the future improvements as payment solutions change over time and can implement API calls necessary to make this idea a reality in X-Payments.
