A memo is a note that is attached to your account when you have made a transaction on your account, but the bank has not actually processed the transaction. Common Memo transactions include debit card transactions, line of credit advances and ATM activity. When the bank processes the transaction, the Memo will be removed and a debit or credit will replace it. The one exception to this process is a debit card transaction. If the merchant where you used your debit card does not process that transaction the same day, the Memo debit will be taken off your account, and your account will be credited back the amount.
