Abstract

A transaction card includes a card body that may comprise a card body comprising a ceramic material, the card body including a primary surface and a first mating surface. A card backer comprises a metallic material and includes a secondary surface and a second mating surface. A portion of the first mating surface and a portion of the second mating surface are coupled together.

First claim

The invention claimed is:

1. A method of making a transaction card comprising:
forming a card body comprising a ceramic material and including a card body aperture, the card body including a primary surface and a first mating surface;
forming a card backer comprising a metallic material and including a secondary surface, a second mating surface, a card backer aperture and a slit extending from the card backer aperture to an exterior edge of the card backer;
coupling together a portion of the first mating surface and a portion of the second mating surface such that the card backer aperture and the card body aperture at least partially overlap;
disposing a fill panel on a portion of the secondary surface of the card backer such that at least a portion of the fill panel is co-extensive with the card backer aperture and completely covers the card body aperture; and
disposing a microchip over the card body aperture and over the card backer aperture such that an unobstructed path exists from at least a portion of the microchip through the card backer aperture and to the fill panel.

2. The method of claim 1 , wherein the forming the card body further comprises:
forming a ceramic material slurry comprising the ceramic material and a binder;
forming a green body from the ceramic material slurry;
firing the green body at a firing temperature to create a fired green body;
grinding the fired green body into the card body; and
polishing the primary surface of the card body.

3. The method of claim 1 , wherein the coupling comprises adhering the portion of the card backer to the portion of the card body with an adhesive.

4. The method of claim 1 , further comprising machining the card backer aperture into the card backer.

5. The method of claim 1 , further comprising machining the slit into the card backer.

6. The method of claim 1 , further comprising forming a pocket in the primary surface.

7. The method of claim 6 , further comprising disposing an integrated RF module into the pocket.

8. The method of claim 6 , further comprising disposing an integrated RF module into the pocket such that a surface of the integrated RF module is flush with the primary surface of the card body.

9. The method of claim 1 , further comprising laser marking the card body to form account indicia.

10. The method of claim 1 , wherein the card body has a thickness of between 0.009 inches and 0.014 inches and wherein the card backer has a thickness of between 0.001 inches and 0.02 inches.

11. The method of claim 1 , wherein the fill panel has a thickness of 0.003 inches to 0.009 inches.

12. The method of claim 1 , wherein a thickness of the card body and a thickness of the card backer combined is 0.03 inches.

13. The method of claim 1 , wherein the card body has a width to height ratio of between 1.4 to 1.8.

14. The method of claim 1 , wherein at least one of the ceramic material or the fill panel comprises at least one of zirconium oxide, zirconium dioxide, boron carbide, or silicon carbide.

15. The method of claim 1 , wherein the metallic material comprises at least one of titanium, aluminum, or stainless steel.

16. The method of claim 1 , wherein the fill panel comprises an exterior surface of the transaction card.

17. The method of claim 1 , further comprising creating a gloss/matte feature on the fill panel.

18. The method of claim 1 , further comprising laser marking a feature on the primary surface, wherein the laser marked feature comprises at least one of an account number, a name, or a loyalty notation.

19. The method of claim 1 , further comprising creating a laser matte feature on the primary surface.

20. The method of claim 1 , further comprising creating a laser matte feature and a polished feature on the card backer.
