That is, the bank will provide your computer with all the checks cleared, update any deposits or withdraws made from any of your accounts. Calling the bank to check on the amount in one of your accounts is no different that the computer calling the bank to find out how much you have in your account. Many banks offer secure lines directly into the bank instead of going out to the public Internet. The real benefit of this information is the financial picture provided by the computer. The computer can display with clarity all of a person's spending habits and help identify ways to increase one's financial worth.
Many banks also offer bill paying with the computer.
Never write out another check to pay a bill. Simply go online, check your account to see how much money you have, and then check off which bills you want to pay. The bank will either electronically pay the bill or print a check and mail it to whomever needs paid. All this without ever picking up a pen, looking for envelope, and finding a stamp. Well if not you are not alone.
