The Automated Clearing House (ACH) Network is one of the largest, safest, and most reliable payment systems in the world. In fact, if your paycheck is directly deposited into your bank account, or you make recurring online bill payments, you’re already using ACH.
The ACH Network is a batch processing system in which financial institutions accumulate ACH transactions throughout the day for later batch processing. Instead of using paper to carry necessary transaction information, such as with checks, ACH Network transactions are transmitted electronically, allowing for faster processing times and lower costs.
