Credit card system and method
DCFirst Claim
1. In a financial transaction system for use with at least one limited use credit card number, which is limited in use by a limited use credit card number issuer, by a customer of the limited use credit card number issuer, and by a user of the limited use credit card number, and which is associated with an account of the customer, a method of controlling the authorization for use of the limited use credit card number comprising the steps of:
- issuing a limited use credit card number for use by a user in a limited use credit card number transaction, the limited use credit card number constituting a different number than the account of the customer and functioning as an authorized substitute for the account of the customer in a credit card transaction;
receiving information communicated by the customer to the limited use credit card number issuer to establish limitations on the use of the limited use credit card number before the limited use credit card number can be used in a transaction by said user;
authorizing transactions which meet said established limitations and denying other transactions by comparing an attempted use of the limited use credit card number to the limitations on use established by the customer and with the associated account as limited by the card issuer; and
debiting said associated account of the customer by an amount of an authorized transaction of the user using the limited use credit card number.

Abstract
A credit card system is provided which has the added feature of providing additional limited use credit card numbers and/or cards. These numbers and/or cards can be used for a single or limited use transaction, thereby reducing the potential for fraudulent reuse of these numbers and/or cards. The credit card system finds application to “card remote” transactions such as by phone or Internet. Additionally, when a single use or limited use credit card is used for “card present” transactions, so called “skimming” fraud is eliminated. Various other features enhance the credit card system, which will allow secure trade without the use of elaborate encryption techniques. Methods for limiting, distributing and using a limited use card number, controlling the validity of a limited use credit card number, conducting a limited use credit card number transaction and providing remote access devices for accessing a limited use credit card number are also provided.
