A smart card device detects that it has interfaced with an interface device and that voltage is now being provided to the smart card device. The smart card device may divert some or most of the current being provided with the voltage to charge an internal battery of the smart card device, either concurrent to other communications between the smart card device and the interface device or before/after relevant communications are completed. As a result, the use of a smart card device contributes to the charge of the smart card device's internal battery, instead of draining it."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Smart card battery charging during card use","description":"Systems, methods, and computer program products are disclosed for dynamically charging an internal battery of a smart card from an interface device (such as a terminal) so that the battery life may be","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621213","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.
