The magnetic axis of the antenna coil can be substantially parallel to a plane defined by the NFC card and not cross the conductive screen. The contactless interface of the NFC card, when selected by the NFC card, can emit data by emitting bursts of magnetic field from the antenna coil, so as to compensate for effects of the conductive screen on a maximum distance for transmitting data by load modulation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication method between a dual interface NFC card inserted into an NFC terminal, and an NFC device","description":"In a general aspect, a method for transmitting data between an NFC card and an external NFC device via a selected interface (e.g., contact or contactless), and further via a contactless interface of t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9793961","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.
