Authorization and Settlement Fee per Transaction: Authorization and settlementfees are charged to issuers and acquirers for the authorization process that Visa performs for each transactions.
Authorization is the process by which MasterCard validates the card, and Settlementfees are charged to issuers for the exchange of funds between issuers and acquirers.
The authorization and settlementfees are most prone to competition, and we expect these fees to decline in the near future since Visa, the nearest competitor to MasterCard, has been reducing its authorization and settlementfees.
