  • Card with electrically conductive points that are readable
    Patent number: 10152616
    Abstract: A card that includes an electrically non-conductive substrate and a plurality of conductive points disposed on a bottom surface of the non-conductive substrate. The conductive points are connected with a coupling point disposed on a top surface of the substrate through vias that extend through the substrate. The conductive points form a pattern that represents an identification of the card and activate locations on a touchscreen of an electronic device. At least three of the conductive points form a predetermined shape such that the electronic device determines a location and an orientation of the card when the card is placed on the touchscreen of the electronic device.
    Type: Grant

  • Substrate with electrically conductive patterns that are readable
    Patent number: 9715687
    Abstract: One embodiment is a flat card that includes an electrically non-conductive substrate and a plurality of electrical conductors disposed on a surface of the non-conductive substrate. The conductors are connected together to form patterns of conductive lines connected to conductive geometric shapes located at ends of the conductive lines. A switch is positioned between two of the conductive geometric shapes and switchable between an open state and a closed state.
