The communication antenna and the receiving coil respond to a magnetic field in the same frequency band for the short-range wireless communication. The wireless communication IC performs short-range wireless communication. The receiving coil receives power from the magnetic field in the same frequency band for the short-range wireless communication. The biometric authentication circuit causes the biometric sensor to operate by using the power received from the receiving resonant circuit. The communication antenna and the receiving coil share electromagnetic field energy resonating in the same frequency band for the short-range wireless communication, the electromagnetic field energy being shared because of magnetic coupling between the communication antenna and the receiving coil."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic card with biometric authentication function","description":"An electronic card with biometric authentication function includes a communication antenna for short-range wireless communication, a wireless communication IC, a receiving coil, a resonant capacitor, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11989608","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.
