Abstract

A card assembly includes an insulating planar body and a magnetic stripe assembly coupled with the planar body. The magnetic stripe assembly includes a magnetic layer configured to magnetically store information and a metal layer that provides at least one of a security feature, a decorative feature, or other functional feature. The metal layer has a small thickness such that the metal layer prevents conduction of electrostatic discharge (ESD) through the magnetic stripe assembly.

First claim

What is claimed is:

1. A card assembly that extends from a first edge to an opposite second edge, the card assembly comprising:
an insulating planar body; and
a magnetic stripe assembly coupled with the planar body, the magnetic stripe assembly including a magnetic layer configured to magnetically store information and a metal layer that provides at least one of a security feature, a decorative feature, or other functional feature,
wherein the metal layer continuously extends from the first edge to the second edge of the card assembly,
wherein the metal layer has a small thickness such that the metal layer prevents conduction of electrostatic discharge (ESD) through the magnetic stripe assembly from the first edge to the second edge of the card assembly.

2. The card assembly of claim 1 , wherein the metal layer comprises at least one of one or more of aluminum, zinc, gallium, indium, cadmium, copper, nickel, cobalt, iron, magnesium, platinum, tin, chromium, silver, rhodium, or palladium.

3. The card assembly of claim 1 , wherein the magnetic stripe assembly has one or more of a reflective mirror surface or a holographic effect.

4. The card assembly of claim 1 , wherein the metal layer of the magnetic stripe assembly has an optical density of at least 0.25.

5. The card assembly of claim 1 , wherein the metal layer of the magnetic stripe assembly has an optical density that is no greater than 4.0.

6. The card assembly of claim 1 , wherein the metal layer is optically continuous without magnification from the first edge of the card assembly to the second edge of the card assembly.

7. The card assembly of claim 1 , wherein the metal layer does not include regularly spaced or arranged spaced-apart metal bodies.

8. The card assembly of claim 1 , wherein the metal layer does not include a repeating arrangement of spaced-apart metal bodies.

9. A magnetic tape assembly comprising:
a magnetic coating layer configured to magnetically store information for a card assembly that extends from a first edge to an opposite second edge; and
a metal layer that provides at least one of a security feature, a decorative feature, or other functional feature of the card assembly, the metal layer continuously extending from the first edge to the second edge of the card assembly and having a small thickness such that the metal layer prevents conduction of electrostatic discharge (ESD) through the card assembly from the first edge to the second edge of the card assembly.

10. The magnetic tape assembly of claim 9 , wherein the metal layer comprises at least one of one or more of aluminum, zinc, gallium, indium, cadmium, copper, nickel, cobalt, iron, magnesium, platinum, tin, chromium, silver, rhodium, or palladium.

11. The magnetic tape assembly of claim 9 , wherein the metal layer includes laser ablating or engraving lines in the metal layer to have one or more of a reflective mirror surface or a holographic effect.

12. The magnetic tape assembly of claim 9 , wherein the metal layer has an optical density of at least 0.25.

13. The magnetic tape assembly of claim 9 , wherein the metal layer has an optical density that is no greater than 4.0.

14. The magnetic tape assembly of claim 9 , wherein the metal layer is optically continuous without magnification.

15. The magnetic tape assembly of claim 9 , wherein the metal layer does not include regularly spaced or arranged spaced-apart metal bodies.

16. The magnetic tape assembly of claim 9 , wherein the metal layer does not include a repeating arrangement of spaced-apart metal bodies.

17. A method comprising:
applying a metal layer to a magnetic tape assembly having a magnetic layer configured to magnetically store information for a card assembly that extends from a first edge to an opposite second edge, the metal layer applied to the magnetic tape assembly in a continuous layer extending from the first edge to the second edge, wherein the metal layer is applied to provide at least one of a security feature, a decorative feature, or other functional feature of the card assembly, the metal layer applied to have a small thickness such that the metal layer prevents conduction of electrostatic discharge (ESD) through the card assembly.

18. The method of claim 17 , wherein the metal layer comprises at least one of one or more of aluminum, zinc, gallium, indium, cadmium, copper, nickel, cobalt, iron, magnesium, platinum, tin, chromium, silver, rhodium, or palladium.

19. The method of claim 17 , wherein the metal layer provides one or more of a reflective mirror surface or a holographic effect.

20. The method of claim 17 , wherein the metal layer is applied to the magnetic tape assembly to have an optical density of at least 0.25.
