What happens between “Pay” and “Paid”
When a customer pays by card online, the checkout page sends payment details through a chain of financial companies. A payment processor carries the transaction data; the card network routes the request to the bank that issued the card; and that bank checks whether the card is valid and funds or credit are available. The response travels back through the chain before the purchase is approved or declined.
The money takes a related route later, when the transaction is settled. The merchant generally receives the sale proceeds minus fees, rather than paying a separate charge at checkout.
Why the fee is divided up
The charge is not necessarily one company’s cut. It can include an interchange fee, paid to the cardholder’s bank, as well as charges associated with the card network and the acquiring bank or processor that serves the merchant. The processor may also charge for its own services, such as connecting a store’s checkout to the payment system and handling transaction records.
These costs reflect different roles: banks and networks help authorize and move payments, while processors provide the machinery merchants use to accept them. The exact fee depends on factors such as the payment method and how the transaction is handled, so there is no single universal rate.
Who ultimately bears the cost?
The merchant pays the transaction fees, but the cost can influence prices, profit margins, or which payment methods a business encourages. A small charge repeated across many purchases can matter to a retailer, especially when margins are thin. For customers, the toll is usually invisible: it is taken out of the merchant’s proceeds, even though several services had to work together for a quick tap or click to become a completed sale.
