An explainer breaks down what Visa and Mastercard actually do, noting they are card networks rather than banks, card issuers, payment processors, or merchant acquirers.

GoKawiil's interpretation of the reporting above, not reported fact.
Confusion over who does what in the payments industry can obscure why certain merchants accept only some cards and how fees get distributed among issuers, processors, and networks. Understanding this structure helps explain the competitive dynamics between incumbents like Visa and Mastercard and newer entrants like Stripe, Square, and Adyen expanding into acquiring.
- Visa and Mastercard are card networks, not banks or card issuers.
- Payment processing and merchant acquiring are separate functions, increasingly handled by fintechs like Stripe and Square.
- Every card transaction involves four distinct roles: issuer, cardholder, network, and acquirer/merchant.
