Abstract: A system and method for managing a financial institution account with a transaction card used as a deferred-debit transaction card and as an automated banking card, wherein debit transactions are stored by a managing computer system for a billing cycle without being automatically debited against the account until after debit transaction activity. In certain instances, this is not until after the activity for the billing cycle is reported to the holder of the account. Also, a limited time period is provided relative to the billing cycle, for the user to provide funds as consideration for payment against the transaction card purchases without an automatic debiting of available funds as full consideration for payment against the deferred-debit purchases. Before the limited time period lapses, the available amount useful for additional purchases can be increased.
