Abstract
A payment card comprises an internal dynamic card verification value (CVV) generator and a user display for card-not-present transactions. Card-present transactions with merchant card readers are enabled by a dynamic magnetic array internally associated with the card's magnetic stripe. The user display and a timer are triggered by the user when the user needs to see the card verification value and/or begin a new transaction. A new card verification value is provided for each new transaction according to a cryptographic process, but the timer limits how soon a next new card verification value can be generated.
