The present invention can unify interfaces of mobile devices, so as to make mobile payment safer and more convenient."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Working method of smart key device","description":"A working method of a smart key device, in which it includes: power on the smart key device; the smart key device reads Bluetooth module parameters, and determines whether the Bluetooth module paramet","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9817961","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.
