Abstract
A magnetic stripe reader includes at least one first sensor and one second sensor respectively delivering a first temporal signal and a second temporal signal proportional to a flux of a magnetic field of the magnetic stripe traveling before the first and second sensors during reading of the stripe by the reader. The first and second sensors are disposed at a pre-determined distance from each other in a sense of travel of the stripe during the reading.

A magnetic stripe reader comprising:
- at least one first sensor and at least one second sensor respectively delivering a first temporal signal and a second temporal signal proportional to a flux of a magnetic field of a magnetic stripe traveling before said first and second sensors during the reading of the stripe by the reader,
- said first and second sensors being disposed at a pre-determined distance from each other in a sense of travel of the stripe during said reading.
A method comprising:
- determining instantaneous speed of travel of a magnetic stripe read by a magnetic stripe reader, comprising:
- reading the magnetic stripe by the magnetic stripe reader, which comprises:
- at least one first sensor and at least one second sensor respectively delivering a first temporal signal and a second temporal signal proportional to a flux of a magnetic field of the magnetic stripe traveling before said first and second sensors during the reading of the stripe by the reader,
- said first and second sensors being disposed at a pre-determined distance from each other in a sense of travel of the stripe during said reading;
- determining an instantaneous speed of travel of said magnetic stripe from said first and second temporal signals and from said pre-determined distance between said first and second sensors.
