Same Day ACH enables faster processing and settlement of ACH transactions on the same business day, for both credit and debit transactions, within established submission deadlines.
Regulation E provides protections for consumers using electronic funds transfers, including ACH transactions, and outlines the rights and responsibilities of consumers and financial institutions in EFT transactions.
ACH transactions are divided into two main types: credit transactions (where funds are pushed to an account, such as direct deposit) and debit transactions (where funds are pulled from an account, such as bill payments).
