Credit card payments are processed in three steps: authorization, clearing, and settlement.  These processes involve multiple components, including card networks, and the systems of merchants, acquirers, and issuers.

In the authorization process, the availability of the card is checked in real-time for each payment transaction. This process involves verifying credit information such as the card's expiration date and credit limit in real-time.

Payment processors, who facilitate online payment transactions, necessarily connect to various networks and POS terminals, depending on the cards used.
