A method and apparatus are disclosed for using temporary data with a magnetic stripe card to reduce incidents of fraudulent card transactions. A first set of temporary data, valid until an occurrence of an event, is generated and applied to a magnetic stripe area of a magnetic stripe card (“the card”). The card can be used for a first transaction, which is authorized based on a verification that the first set of temporary data is valid, or was valid and is not expired. The transaction is processed based on an account associated with the card. The event occurs, rendering the first data item invalid, and a second set of temporary data is generated and applied to the magnetic stripe area. |

1. A method comprising:
causing, by a processor coupled to a magnetic stripe card, a magnetic stripe area of the magnetic stripe card to bear a first card verification value (CVV) that can be read by a magnetic stripe card reader during a first swipe of the magnetic stripe card through the magnetic stripe card reader, the first CVV being valid until a first event, the magnetic stripe area further bearing an account number associated with a financial account, the magnetic stripe card being capable of use to initiate, while the first CVV is valid, a first payment, to be made based on the financial account, by being swiped using the first magnetic stripe card reader; and after the first event, causing, by the processor coupled to the magnetic stripe card, the magnetic stripe area to bear a second CVV that can be read during a second swipe of the magnetic stripe card,
the second CVV being valid only until a second event,the magnetic stripe area further bearing the account number associated with the financial account,the magnetic stripe card being capable of being used to initiate, while the second CVV is valid, a second payment, to be made based on the financial account, by being swiped. |
