Ways are provided to allow a credit card issuing financial institution and the card member to customize a credit card account by defining an unlimited number of special-purpose lines of credit, while maintaining the overall risk at or below the overall line of credit. The individual specialized lines of credit share the overall line of credit, where the total amount of credit actually extended to the card member based on one or more of the specialized lines of credit is limited by the overall line of credit. To provide flexibility in allocating credit toward a plurality of different expenses, the sum of all of the individual lines of credit is preferably greater than the overall line of credit. Therefore, numerous special-purpose lines of credit are created for promotional, budgetary, fraud prevention, or other purposes, without negatively affecting the consumer's credit profile and/or credit score.
