Abstract
This disclosure is directed to an electronic identification card or electronic card having various features. The electronic card may include an integrated circuit and a contact plate for electrically interfacing with the integrated circuit. The contact plate may include an array of terminal electrodes that are offset with respect to the edges of the contact plate. The electronic card may be coated with a coating layer that extends at least partially over a ferromagnetic element or film. The electronic card may also include a metal substrate having exposed chamfer portions that may provide a visual contrast to the coating layer and also improve the handling and use of the electronic card.
Claims20
An electronic credit card comprising:
- a substrate defining a recess formed into a front surface;
- an integrated circuit positioned in the recess of the substrate;
- and
- a contact plate positioned over the integrated circuit and comprising:
- a plate substrate;
- an array of terminal electrodes disposed over the plate substrate, each terminal electrode of the array of terminal electrodes offset from an edge of the plate substrate;
- and
- a peripheral portion that includes a conductive material that surrounds each terminal electrode of the array of terminal electrodes, the peripheral portion separated from each terminal electrode of the array of terminal electrodes by a gap, wherein the peripheral portion defines an array of oval-shaped openings and each terminal electrode of the array of terminal electrodes is positioned within a respective opening of the array of oval-shaped openings.
An electronic card comprising:
- a metal substrate;
- and
- a contact plate positioned at a second surface of the metal substrate opposite to the first surface, the contact plate comprising:
- a substrate comprising a dielectric material;
- an array of terminal electrodes disposed over a first surface of the substate, each terminal electrode of the array of terminal electrodes formed from a first conductive material;
- and
- a conductive coating disposed over the first surface of the substrate and formed from a second conductive material, the conductive coating defining an array of oval-shaped openings, each respective oval-shaped opening surrounding a respective terminal electrode of the array of terminal electrodes.
An electronic card comprising:
- a substrate defining a recess;
- an integrated circuit positioned in the recess;
- and
- a contact plate positioned over the integrated circuit and comprising:
- a plate substrate;
- a peripheral portion positioned on the plate substrate, the peripheral portion including a conductive material defining an array of oval-shaped openings;
- and
- an array of terminal electrodes positioned on the plate substrate, each terminal electrode of the array of terminal electrodes positioned within a respective oval-shaped opening of the array of oval-shaped openings and surrounded by the peripheral portion.
