A front metal layer may be continuous (no slit), and may be shielded from underlying metal layers by a shielding layer (SL). Metal backing inserts (MBI) reinforcing the slit(s) may also have a slit (S2) overlapping the module antenna. Diamond like coating filling the slit. Key fobs similarly fabricated. Plastic-Metal-Plastic smart cards and methods of manufacture are disclosed. Such cards may be contactless only, contact only, or may be dual-interface (contact and contactless) cards."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Smart cards, payment objects and methods","description":"Smartcards having (i) a metal card body (MCB) with a slit (S) overlapping a module antenna (MA) of a chip module (TCM) or (ii) multiple metal layers (M1, M2, M3) each having a slit (S1, S2, S3) offset","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9836684","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.
