| Offline debit card | Cards that share traits of both ATM and credit cards. Offline debit cards have the VISA or MasterCard logo on them and can be issued by a bank, either instead of or in addition to an ATM card. These cards can be used at any establishment that displays the VISA or MasterCard logo, but using them doesn't access a line of credit -- it debits a customer's checking account. It is "offline" because the account isn't directly accessed -- there's a delay of 24 to 72 hours before the debit is made in the account. If you sign a slip of paper to conclude the transaction, it was offline. In the U.S., no Personal Identification Number (PIN) is required to use an offline debit card. |
| Online banking | Access by personal computer or terminal to bank information, accounts and certain transactions via the financial institution?s web site on the Internet. Also known as Internet banking. |
| Online bill payment | A service offered by online banks, usually for a small monthly fee, that relieves consumers from having to write checks and lick stamps to pay their monthly bills. Online bill payment systems allow people to enter the names of their creditors and the numbers of their utility accounts and pay virtually all routine bills. |
| Online debit card | An online debit card deducts funds from the bank account immediately, as soon as the card is used. It may have the VISA or MasterCard logo, or only the issuing bank's logo, like an ATM card. There is no delay for processing the transaction -- the money is immediately deducted from your account. In the U.S., if you entered a Personal Identification Number (PIN) during the transaction, it was online. |
| Open-end credit | A line of credit that may be used up to a set limit. Also called a charge account or revolving credit. |
| Original principal balance | The amount borrowed. |
| Over-the-limit fee | A fee charged for exceeding the credit limit on the card. |
| Overdraft | The amount that a check exceeds the available balance in the payor's account; also insufficient funds. |
| Overdraft protection | A service that allows a checking account to be linked to another savings or line of credit to provide protection against insufficient funds or overdrafts. |
