Abstract
A transaction card having a self-programming region that allows periodic update of security data is disclosed. The self-programming region contains one or more self-programming components, each of which can be switched between two states depending on the direction of an electrical current provided to the component. The self-programming components are used for updating security data such as a digital code at various time intervals as determined by an algorithm in a processor on the card.
