Interchange feesnounMWEFees paid by one financial institution to another to cover handling costs and credit risk in a financial institution card transaction. Interchange fees generally flow toward the institution funding the transaction and assuming the risk. In a credit card transaction, the interchange fee is paid by the merchant acquirer accepting the merchant's sales draft to the card-issuing institution, which, in turn, passes the fee to its merchants. In EFT/POS transactions, interchange flows in the opposite direction: the card-issuing institution (or customer) pays the fee to the terminal-owning institution. When a transaction is an off-line debit sale, the card-issuing institution collects an interchange fee from the merchant, rather than from the customer, unlike in an EFT/POS transaction, where the customer pays the interchange fee. Interchange revenue is derived from fees set by the card associations. Depending on the card association, fees can range from 1% to 3% of the value of the transaction. Interchange revenue is recognized as a card issuer's second largest revenue line item.RequirementRegulated

interconnected systemnounMWEA configuration of two or more distinct IT systems—spanning organizational, network, or authorization boundaries—that are directly linked for the purpose of sharing data, resources, or services. What distinguishes it from a single system with internal components is the presence of a cross-boundary connection that introduces shared risk: each party's security and privacy posture can affect the other's, which is why authority documents treat the connection itself as a security object requiring its own governance instruments (interconnection security agreements, architectural controls, and joint authorization). In practice, standards bodies use the term to frame obligations such as mandating specific architectural constraints, documenting mutual protection requirements, and maintaining the confidentiality, integrity, and availability of information as it moves across the join.SystemRegulatedCUI
