A metal card body (MCB, CB) or a transaction card with a discontinuous metal layer having a slit (S) or a non-conductive strip (NCS, 1034) extending from a module opening (MO) to a periphery of the card body to function as a coupling frame (CF). The coupling frame (CF) may be thick enough to be non-transparent to RF at frequencies of interest. A switch (SW) may be provided to connect ends of the coupling frame (CF) across the slit (S, 630). A reinforcing structure (RS) may be provided to stabilize the coupling frame (CF) and card body (CB). The transponder chip module (TCM) may comprise an antenna structure which may be a laser-etched antenna structure (LES) or a chemical-etched antenna structure (CES), and may comprise and a non-perforated contact pad (CP) arrangement. A coupling frame (CF) may be incorporated onto the module tape (MT, CCT) for a transponder chip module (TCM)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Smartcard with coupling frame and method of increasing activation distance of a transponder chip module","description":"A conductive coupling frame (CF) having two ends, forming an open loop having two ends or a discontinuous metal layer disposed surrounding and closely adjacent a transponder chip module (TCM, 610), an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9798968","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.
