How card processing works
When a card is presented, the terminal sends an authorization request through the acquirer to the card network and issuing bank. Approved transactions are batched at the end of the day, cleared through the network, and funded to your bank account. Interchange set by the networks, assessments, and processor markup all come out of that flow in a conventional account. On a zero-fee program the acceptance cost is collected at the register instead, so the deposit arrives whole.
