Abstract

A transaction card that includes a card body that can include a ceramic material. The card body can include a primary surface and a secondary surface, a laser marked feature disposed on the card body and a laser etched feature disposed on the card body. A method of making a transaction card can include forming a ceramic material slurry comprising a 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 ceramic body, grinding the fired ceramic body into a card body, and polishing a primary surface of the card body.

First claim

Therefore, we claim:

1. A transaction card manufactured by a process of:
creating a ceramic card body comprising a binder in a ceramic material and fiber reinforcing the ceramic material;
laminating a layer of metal to a primary surface of the ceramic card body;
creating a pocket in the primary surface of the ceramic card body of the transaction card, the pocket extends through the layer of metal;
depositing a magnetic stripe and a signature panel on a secondary surface of the ceramic card body;
creating a recess comprising an opening in the pocket;
disposing an insulated material in the pocket and positioned between an integrated radio frequency (RF) module and the ceramic card body, the insulated material acting as an adhesive and to electrically insulate the integrated RF module and the ceramic card body disposing an entirety of a first side of the integrated RF module into the pocket, such that an outer portion of the first side of the integrated RF module rests in the pocket; and
resting an inner portion of the first side of the integrated RF module in the opening of the recess.

2. The transaction card of claim 1 manufactured by the process further comprising laser finishing the primary surface to add a laser matte feature disposed directly in the ceramic material, wherein the laser matte feature comprises at least a portion of the primary surface.

3. The transaction card of claim 1 manufactured by the process further comprising laser cutting the primary surface to form a chamfered edge between the primary surface and a side surface.

4. The transaction card of claim 1 manufactured by the process further comprising laser cutting the pocket into the primary surface.

5. The transaction card of claim 1 manufactured by the process further comprising:
forming a ceramic material slurry comprising the ceramic material, the binder, and the fiber;
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 ceramic card body; and
polishing the primary surface of the ceramic card body.

6. The transaction card of claim 1 manufactured by the process further comprising leveling a second side of the integrated RF module to be flush with the primary surface.

7. The transaction card of claim 1 manufactured by the process further comprising extending the recess in a direction of the secondary surface.

8. A transaction card, comprising:
a ceramic card body comprising a fiber-reinforced ceramic material;
a metal layer laminated to a primary surface of the ceramic card body;
a pocket in the primary surface of the ceramic card body, the pocket extending through the metal layer;
an integrated radio frequency (RF) module located within the pocket, the integrated RF module comprising an antenna;
an electrically insulated material in the pocket positioned between the integrated RF module and the ceramic card body, the electrically insulated material acting as an adhesive to bind the integrated RF module to the ceramic card body; and
a magnetic stripe placed on a secondary surface of the ceramic card body.

9. The transaction card of 8 , wherein a first side of the integrated RF module is flush with the primary surface of the ceramic card body.

10. The transaction card of 8 , wherein:
the pocket has a recess; and
the integrated RF module is positioned with an entirety of a first side of the integrated RF module in the pocket, such that an outer portion of the first side rests in the pocket and the inner portion of the first side rests in the recess of the pocket.

11. The transaction card of 8 , further comprising a laser matte feature disposed on the primary surface.

12. The transaction card of 8 , further comprising a chamfered edge between the primary surface and a side surface.
