The debit credit rules for bank accounts refer to the methods for recording and settling financial transactions. Essentially, it is the protocol used by banks to record when money has been either received or spent. It ensures accuracy when recording financial activity and tracks all money moving throughout different accounts. A key component of the debit credit rules is double-entry bookkeeping, which requires that each transaction be recorded twice, providing a backup system of checks and balances to ensure accuracy. Following these rules ensures that bank account transactions are documented accurately, helping to protect both customers and financial institutions from fraud.
