Investopedia explains 'Transaction Deposit'
Transaction deposits must be held in reserve by the bank at all times; they stand in contrast to time deposits and even deposits into a savings account, which may have monthly limitations on the number of transactions or transfers allowed.
Making a deposit into a conventional checking account will be considered a transaction deposit, as the account holder is allowed to withdraw the amount at any time.
