ACH is an initialization that stands for Automated Clearing House. The ACH is an electronic network that connects all banks, and other financial organizations, in the United States. ACH transfers, sometimes referred to as EFT (Electronic Funds Transfer), are a bank-to-bank transaction. As a payment method, this means that American players can make payments from their accounts to a live casino’s account.
For the most part, ACH payments are very similar to wire transfers, in that wire transfers are also another form of bank-to-bank transactions. The main difference is that bank transfers are processed in real-time (ACH transfers are processed three times a day) and that ACH payments are usually much cheaper in terms of fees. This affordability is why most employers use it to process payroll deposits, and why it is supported by many live casinos. Also, ACH is only available to Americans while wire transfers work internationally.
