Credit Card Processing: The Working Mechanism Behind the Whole Process Having the intimate knowledge about the inner-workings of the bankcard system is not mandatory but then there's no harm in knowing it. Understanding how things actually work is a good approach, as fees are incurred at times at one or the other stage. The main components in the whole process involve:
1. ​Key players 2. ​Credit card authorization 3.​ Credit card clearing and settlement
Credit card processing services are so quick and timely that within few seconds, transaction details are transferred from the terminal to a processor. Later, this information is passed through the card network to the issuing bank. Once all this happens, the issuing bank sends an authorization back to the processor via the network.
