Abstract
Provided is a card having processed areas includes a core layer, an antenna pattern on the core layer, and one or more bump-out areas of the antenna pattern having a threshold distance towards a process boundary, where the card passes a continuity test if a cutting or a punching or a milling process fails to create an open circuit at the bump-out areas. The card fails a continuity test if the cutting or the punching or the milling processes creates the open circuit at the bump-out areas. Additional steps can be included along with other embodiments.
Claims23
A card comprising:
- a core layer;
- an antenna pattern on the core layer;
- and
- one or more bump out-areas of the antenna pattern having a threshold distance towards a process boundary, wherein the card is configured to pass a continuity test if a cutting process fails to create an open circuit at the bump-out area.
A card comprising:
- a core layer;
- an antenna pattern on the core layer;
- and
- one or more bump out-areas of the antenna pattern having a threshold distance towards a process boundary, wherein the card is configured to pass a continuity test if a cutting process fails to create an open circuit at the bump-out area,
- wherein the threshold distance is a borderline distance of an embossing area to detect and avoid overprinting of the embossing area over the antenna area pattern on the core layer.
A card comprising:
- a core layer;
- an antenna pattern on the core layer;
- and
- one or more bump out-areas of the antenna pattern having a threshold distance towards a process boundary, wherein the card is configured to pass a continuity test if a cutting process fails to create an open circuit at the bump-out area,
- wherein the threshold distance is a borderline distance of a security feature to detect and avoid overprinting of a security feature area over the antenna area pattern on the core layer.
A method of forming a card according to having a core layer;
- an antenna pattern on the core layer;
- and one or more bump out-areas of the antenna pattern having a threshold distance towards a process boundary, wherein the card is configured to pass a continuity test if a cutting process fails to create an open circuit at the bump-out area,
- said method comprising:
- providing a core layer,
- providing an antenna pattern on the core layer, and
- providing one or more bump out-areas of the antenna pattern having a threshold distance towards a process boundary,
- wherein the method comprises a step of continuity test consisting of a cutting process for forming at least part of the card said continuity test being considered as passed or positive if said cutting process fails to create an open circuit at the bump-out area.
