Payment networks provide the infrastructure (rails) through which funds flow between payers and recipients. They come in different flavors based on settlement speed, supported transaction types, costs, and operational hours.
How do payment networks work?
- Card networks route and police card transactions between acquirers and issuers. These 24/7 networks are most used for purchases and bill payments. They include dual-message networks like Visa, Mastercard, American Express, and Discover, which send authorization and settlement communications separately. Single-message (PIN) debit networks, such as Interlink, STAR, and Pulse, bundle them into one message.
- Automated Clearing House (ACH) networks route electronic funds transfers between payer and payee accounts. In the US, these transactions are routed through two not-for-profit networks—the Federal Reserve and The Clearing House. Transactions are categorized as debits withdrawn from payers’ accounts (recurring bill payments) or credits to those accounts (direct deposits or tax refunds). The average ACH transaction costs payees pennies per transaction, versus rates as high as 2.5% for card transactions.
- The account-to-account (A2A) instant payments network FedNow has joined the club. Launched in July 2023, the government-run service processes transactions in real time and, like ACH, for a lower cost than card transactions. However, transactions cannot be reversed once complete. FedNow is available to all US banks and credit unions regardless of size.
Card payment networks capture around $130 billion in US revenues
- Revenues among the Big Four US card payment networks topped $129 billion in 2023. They’re in the business of making money, unlike ACH networks and FedNow. Visa and Mastercard earn network fees from other parties to the transaction. American Express and Discover network operators also earn revenues via direct acquiring relationships with merchants and issuing their own cards. All four also earn revenues from value-added services.
