In a typical embodiment, the card (e.g., a credit card, a debit card and/or a smart card) comprises (among other things) an energy component for providing power to the card. Upon powering up via a light source, including light from the interfacing terminal's backlight, a terminal (e.g., a point of sale terminal) will scan/read card information shared between the card and the card company (e.g., upon swiping or placing of the card), and generate a corresponding source validation code (SVC). An optional imager/image array positioned on the back of the card will scan/read the SVC, and card validation code (CVC) logic on the card will generate a CVC based on the SVC (e.g., based on a validation result of the SVC)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light-powered smart card for on-line transaction processing","description":"In general, embodiments of the present invention relate to a light-powered smart card and associated methods for automated information (static and dynamic) exchange pursuant to a commercial transactio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8490872","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.
