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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Payment card with dynamic account number","description":"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 t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8494959","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
