Typical Transaction. Our core network supports what is often referred to as a “four-party” payments network.
In a typical transaction, an account holder purchases goods or services from a merchant using one of our payment products. After the transaction is authorized by the issuer, the issuer pays the acquirer an amount equal to the value of the transaction, minus the interchange fee and then posts the transaction to the account holder’s account. The acquirer pays the amount of the purchase, net of a discount to the merchant.
