20090048970 | Approval and Issuance of a Financial Card - A method comprising issuing, at a virtual credit card issuer, a virtual credit card to an entity and debiting a monetary amount from a credit card account associated with a credit card issued by a financial institution that has extended credit to the entity. The method also comprises crediting the monetary amount to a virtual credit card account associated with the virtual credit card. The virtual credit card issuer would receive a request for payment directly from a merchant who accepted a credit card number of the virtual credit card as a form of payment from the entity. The request for payment when a monetary amount specified by the request for payment is less than or equal to the monetary amount credited to the virtual credit card account associated with the virtual credit card would be honored. | 02-19-2009 |
20090173782 | Dynamic Card Validation Value - As described herein, a card services provider dynamically generates a card verification value (CVV) for a transaction card and sends the dynamically-generated CVV to a cardholder. The card services provider generates the dynamically-generated CVV such that the dynamically-generated CVV is substantially unpredictable based on other dynamically-generated CVVs for the transaction card. The dynamically-generated CVV is only valid for a limited period of time and/or for a limited number of economic transactions. The cardholder uses the dynamically-generated CVV as part of an economic transaction with a merchant. Because the dynamically-generated CVV is only valid for a limited number of economic transactions and/or for a limited period of time, it may be difficult for a thief to repeatedly use the transaction card to make economic transactions. | 07-09-2009 |
20120059762 | Dynamic Card Verification Value - As described herein, a card services provider dynamically generates a card verification value (CVV) for a transaction card and sends the dynamically-generated CVV to a cardholder. The card services provider generates the dynamically-generated CVV such that the dynamically-generated CVV is substantially unpredictable based on other dynamically-generated CVVs for the transaction card. The dynamically-generated CVV is only valid for a limited period of time and/or for a limited number of economic transactions. The cardholder uses the dynamically-generated CVV as part of an economic transaction with a merchant. Because the dynamically-generated CVV is only valid for a limited number of economic transactions and/or for a limited period of time, it may be difficult for a thief to repeatedly use the transaction card to make economic transactions. | 03-08-2012 |
20130054466 | Dynamic Card Verification Value - As described herein, a card services provider dynamically generates a card verification value (CVV) for a transaction card and sends the dynamically-generated CVV to a cardholder.
