Is a pricing model that consists of three components: IC represents the interchange fees assessed by the issuing bank, the first plus signifies a markup charged by the payment processor, and the second plus represents a scheme fee directly levied by card schemes like Visa and MasterCard. In this model, the payment processor’s markup remains fixed, while the other two elements vary dynamically based on factors such as card type (debit or credit), card network (Visa or MasterCard), transaction type (domestic or cross-border), and card category (business or consumer).
