The Interchange fee is charged by the cardholder's Issuing Bank. There are over 100 variations of Interchange fees which depend on the type of transaction (card-present, card-not-present, full 3D, partial 3D, etc.), merchant industry, the type of the card used (Prepaid, Debit, Credit, Premium, Commercial, etc.), and the country of the merchant and the cardholder's Issuing Bank.
Card Scheme & Technical Transaction Processing fee
The “++” in the IC++ pricing model is a card scheme fee and the cost of technology (technical transaction processing cost). This fee is charged by the Acquirer’s Processing center and the International Payment Systems (e.g., Visa, Mastercard) for using their network.
Payment Acquirer margin
The fee “%”, which goes after the IC++ (ex. IC++ 0.3%), is the actual margin of the specific payment Acquirer, collected to process the payments. In the case of the IC++ fee structure, the payment Acquirer is openly showing their costs (IC++) and their margins, so the merchant may see the real fee that goes to the Acquirer’s pocket to process the payment.
If you have any questions regarding the pricing model, feel free to approach your account manager.
