Answer by SumDude
ACH = Automated Clearing House, where banks trade checks and settle up the debts and transfers of their customers. Used to be with the real paper checks people wrote, but now more electronic. The credit card company just makes an electronic image of your check*, and your bank (through the ACH) gives the money (as an electronic credit) to the cc company, and deducts the balance from your checking account; and your bill to the cc company is settled (paid).

* or totally electronic debits and credits if you pay on line.
