Card schemes enable a simplified and guaranteed exchange of money between merchants, customers and their banks, by operating international networks and setting uniform standards. More specifically, they define rules for the routing of payment authorizations and settlement requests in point-of-sale and e-commerce transactions between merchant acquirers and card issuers, as well as ATM withdrawals or purchases with cashback transactions.
