The disturbing magnetic field generator may include a core part including a core formed and a disturbing magnetic field generation coil wound around the core. The core part may include a first end face and a second end face which are disposed so as to face substantially the front side. The disturbing magnetic field generator may generate a disturbing magnetic field whose flux line changes into a direction from the first end face toward the second end face and a direction from the second end face toward the first end face. The direction of the magnetic flux lines are substantially parallel to the passing direction of the card. In a width and thickness direction of the card, the magnetic flux line crosses a position where the magnetic stripe is passed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Card reader","description":"A card reader may include a card insertion port; a card passage; and a disturbing magnetic field generator.
