Abstract

A flexible card may include a dynamic magnetic stripe communications device having multiple layers, such as an electromagnetic generator, a magnet, and a shield. A shield may form a non-flexible layer within the stack and may bend, but the shield may not be able to stretch or compress. Flexible layers may surround and adhere to the shield such that when the card is flexed, the flexible layers may stretch and compress with the movement of the shield. The dynamic magnetic stripe communications device may include one or more coils. Each coil may contain a material that may be beveled, such that a width at an end portion of the material may be smaller than a width at a middle portion of the material.

Claims

1. A card comprising:

a dynamic magnetic stripe communications device including a plurality of layers, said plurality of layers including,

an electromagnetic generator including a coil, and

a material layer,

wherein a first portion of said material layer is within an end portion of said coil,

a second portion of said material layer is within a middle portion of said coil, and

a width of said first portion of said material layer at said end portion of said coil is less than a width of said second portion of said material layer at said middle portion of said coil.

2. The card of claim 1, wherein said material layer is a plurality of material layers.

3. The card of claim 1, wherein said material layer is at least three stacked material layers.

4. The card of claim 1, wherein said material layer is entirely within said coil.

5. The card of claim 1, wherein said first portion is at least part of an end portion of said material layer.

6. The card of claim 1, wherein said first portion is at least part of a beveled end portion of said material layer.

7. The card of claim 1, wherein said first portion is at least part of a beveled end portion of said material layer, and

a width of said beveled end portion decreases linearly to zero.

8. The card of claim 1, wherein said first portion is at least part of a beveled end portion of said material layer, and

a width of said beveled end portion does not decrease linearly to zero.

9. The card of claim 1, wherein said first portion is at least part of an end portion of said material layer, and

a shape of said end portion of said material layer is concave.

10. The card of claim 1, wherein said first portion is at least part of an end portion of said material layer, and

a shape of said end portion of said material layer is convex.

11. The card of claim 1, wherein said first portion is a partially beveled end portion of said material layer.

12. The card of claim 1, wherein said first portion is beveled.

13. The card of claim 1, wherein said first portion is beveled, and

a width of said first portion decreases linearly to zero.

14. The card of claim 1, wherein said first portion is beveled, and

a width of said first portion does not decrease linearly to zero.

15. The card of claim 1, wherein a shape of said first portion is concave.

16. The card of claim 1, wherein a shape of said first portion is convex.

17. The card of claim 1, wherein said first portion is at least partially beveled.

18. The card of claim 1, wherein said second portion is between said first portion and a third portion of said material layer,

said third portion is within a second end portion of said coil, and

a width of said third portion at said second end portion is less than a width of said second portion.

19. The card of claim 1, wherein said dynamic magnetic stripe communications device includes a magnet.

20. The card of claim 1, wherein said dynamic magnetic stripe communications device includes a magnet and a shield.

21. The card of claim 1, wherein said first portion of said material layer includes a magnetic material.
