Abstract

Methods and apparatus for encoding information on a magnetic stripe of a transaction card are disclosed. According to one aspect, a transaction card includes a first surface and a second surface that substantially opposes the first surface. The second surface has a magnetic stripe. A first representation of a first pattern and a second representation of the first pattern can be encoded on the magnetic stripe. In one embodiment, the first representation can be encoded beginning at approximately a first distance from a first edge of the second surface, and the second representation can be encoded to within approximately the first distance from a second edge of the second surface.

Claims

1. A transaction card comprising:

a first surface; and

a second surface, the second surface being arranged to substantially oppose the first surface, the second surface including a magnetic stripe, the magnetic stripe having a first representation of a first pattern encoded thereon, the magnetic stripe further having a second representation of the first pattern encoded thereon, the first representation being encoded beginning at approximately a first distance from a first edge of the second surface, the second representation being encoded to within approximately the first distance from a second edge of the second surface.

2. The transaction card of claim 1, wherein the first distance is approximately 0.25 inches.

3. The transaction card of claim 1, wherein the second representation is a mirror image of the first representation.

4. The transaction card of claim 3, wherein the second representation is encoded beginning at approximately the first distance from the second edge.

5. The transaction card of claim 3,

wherein the first representation of the first pattern includes a first start sentinel and ends with a first end sentinel, the first start sentinel being positioned at approximately the first distance from the first edge, and

wherein the second representation includes a second start sentinel and ends with a second start sentinel, the second start sentinel being positioned at approximately the first distance from the second edge.

6. The transaction card of claim 5, wherein the first start sentinel corresponds to a first character and the second start sentinel is the first character.

7. The transaction card of claim 6, wherein the first end sentinel corresponds to a second character and the second end sentinel is the second character.

8. The transaction card of claim 3, wherein the first representation of the first pattern is positioned between a first start sentinel and a first end sentinel, the first start sentinel being positioned at approximately the first distance from the first edge, and wherein the second representation is positioned between a second start sentinel and the first end sentinel, the second start sentinel being positioned at approximately the first distance from the second edge.

9. The transaction card of claim 1, wherein a bottom edge of the magnetic stripe is positioned at approximately 0.223 inches from a bottom edge of the second surface.

10. A transaction card comprising:

a surface, the surface including a first edge and a second edge; and

a magnetic stripe incorporated onto the surface, the magnetic stripe having a first sequence encoded thereon, the magnetic stripe further having a second sequence encoded thereon, the second sequence being a mirror image of the first sequence, wherein a beginning of the first sequence is encoded beginning at approximately a first location associated with a first distance from the first edge and an end of the second sequence is encoded at a second location associated with approximately the first distance from the second edge.

11. The transaction card of claim 10 wherein the first sequence begins with a starting sentinel and ends with an ending sentinel, the starting sentinel being encoded at the first location.

12. The transaction card of claim 10 wherein the first distance is approximately 0.25 inches.

13. The transaction card of claim 10 wherein the first edge and the second edge are separated by a first width that is at least approximately 3.375 inches, and the magnetic stripe has a second width that is approximately equal to the first width.

14. A method for providing information on a magnetic stripe of a transaction card, the method comprising:

obtaining a first sequence that represents a pattern to be encoded onto the magnetic stripe, the first sequence including a starting sentinel and an ending sentinel, the starting sentinel being arranged to indicate a start of the first sequence, the ending sentinel being arranged to indicate an end of the first sequence;

creating a second sequence that represents the pattern to be encoded onto the magnetic stripe, the second sequence including at least a first sentinel;

encoding the first sequence on the magnetic stripe such that the starting sentinel is located at a first location that is approximately a first distance from a first edge of the magnetic stripe; and

encoding the second sequence on the magnetic stripe such that the first sentinel is located at a second location that is approximately the first distance from a second edge of the magnetic stripe.

15. The method of claim 14 wherein the second sequence is a mirror image of the first sequence, and the first sentinel is the starting sentinel.

16. The method of claim 14 wherein the first distance is approximately 0.25 inches.

17. The method of claim 14 wherein the magnetic stripe has a width of approximately 3.375 inches or more.

18. A computer-readable medium suitable for providing information on a magnetic stripe of a transaction card, the computer-readable medium comprising:

code devices that cause a first sequence to be created that represents a pattern to be encoded onto the magnetic stripe, the first sequence including a starting sentinel and an ending sentinel, the starting sentinel being arranged to indicate a start of the first sequence, the ending sentinel being arranged to indicate an end of the first sequence;
