Four-Party Model

What is Four-Party Model?

The four-party model is the organizational structure used by major card networks like Visa and Mastercard. It involves four main participants: the cardholder, the merchant, the issuer (customer’s bank), and the acquirer (merchant’s bank).

The card network itself acts as the central hub that connects these four parties. This model allows for a competitive and scalable ecosystem where any bank can issue cards that are accepted by any merchant.

Why It Matters

• Creates a standardized framework for global payment acceptance

• Allows for competition among many different banks and processors

• Ensures that cardholders can use their cards at millions of locations

• Defines the flow of data and funds for the majority of card transactions
