Abstract

A card may utilize an extended dynamic magnetic stripe communications device that may extend to approximately the full length of a card. A processor of a card may detect movement (e.g., position, velocity, acceleration and movement direction) of a read head in relation to movement of the card while the card is being swiped or otherwise moved across a read head of a magnetic card reader. Based on certain parameters (e.g., length characteristics of an extended dynamic magnetic stripe communications device as may be received from a memory of the card, initially detected read head position, and read head velocity) a processor of the card may change communicated bit parameters (e.g., bit period) so that a total number of data bits may be communicated by the card to the read head while the read head remains within a communication distance of the extended dynamic magnetic stripe communications device.

Claims

1. A method, comprising:

detecting position variations of a read head in relation to a card;

determining a length of an extended dynamic magnetic stripe communications device on said card;

calculating a time window to communicate data to said read head based on said position variations and said length; and

selecting communication parameters to communicate said data within said time window.

2. A card, comprising:

a processor;

a memory;

an extended dynamic magnetic stripe communications device, wherein said processor receives dimensions of said extended dynamic magnetic stripe communications device from said memory to select communication parameters used when communicating with a read head of a magnetic stripe reader.
