Abstract
A payment card comprises a processor, a trigger source coupled to the processor, and a display for outputting at least a portion of a dynamic account number under control of the processor responsive to the trigger source. The dynamic account number is determined based at least in part on a seed stored in the payment card and an output of the trigger source. In an illustrative embodiment, the dynamic account number is generated utilizing a time-based or event-based one-time password algorithm. For example, in a time-based embodiment, the trigger source may comprise a time of day clock, with the dynamic account number being determined based at least in part on the seed and a current value of the time of day clock. In an event-based embodiment, the trigger source may comprise an event counter, with the dynamic account number being determined based at least in part on the seed and a current value of the event counter.
