Automated Clearing House (ACH)

The Automated Clearing House, or ACH, is a network of financial institutions that processes many types of consumer payments, including debit and credit card transactions. Most consumers don't interact directly with the system, but if you have a direct deposit of your check or make a monthly mortgage payment, you're likely using the Automated Clearing House transaction network.
