Abstract
A card core includes a body defining a cutout and a discontinuity. The cutout includes an opening in the body defined by an edge and the discontinuity includes a channel defined by the body extending from an outer surface of the body to the cutout. The cutout is sized and configured to define a gap between an element positioned in the cutout and the edge to electromagnetically isolate the element from the body.
Claims30
A card core comprising:
- a ceramic body defining a cutout having an opening bounded by an inner edge;
- and
- a discontinuity comprising a channel in the ceramic body extending from an outer edge surface of the ceramic body to the inner edge of the cutout, the channel including at least one curved portion and at least one straight portion, wherein the cutout is sized and configured to receive a circuit element and to maintain a gap between the circuit element and the inner edge so as to electromagnetically isolate the circuit element from the ceramic body.
A credential card comprising:
- a card core including a ceramic body defining a cutout and a discontinuity comprising a channel extending from an outer edge surface of the ceramic body to an inner edge of the cutout, the channel including at least one curved portion and at least one straight portion;
- a first material layer disposed over a first side of the card core;
- and
- a second material layer disposed over a second side of the card core;
- wherein the first material layer is coupled to the second material layer in a position substantially aligned with the cutout.
2 more elements
A card core comprising:
- a ceramic body defining a plurality of cutouts spaced about the body, each cutout including an opening bounded by an inner edge and comprising at least two portions having different geometries that at least partially overlap;
- and
- for at least one of the plurality of cutouts, a discontinuity in the ceramic body extending from an outer edge surface of the ceramic body to the inner edge of that cutout, the discontinuity selected from a sinuous line discontinuity including curved and straight portions and a straight line discontinuity, the discontinuity having a width sufficient to prevent electromagnetic coupling across the discontinuity.
