The metal detecting mechanism may include an exciting coil and a detecting coil. The jamming magnetic field generation mechanism may include a jamming magnetic field generating coil. The control unit may be structured to alternately switch between a current supply to the exciting coil and a current supply to the jamming magnetic field generation coil, and detect the external connection terminal on the basis of an output from the detecting coil at a time when the exciting coil is supplied with a current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Card reader and control method therefor","description":"A card reader may include a card insertion slot into which the card is inserted; a metal detecting mechanism structured to detect the external connection terminal of the card inserted into the card in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9754135","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.
