Abstract
A magnetic stripe transmission (MST) apparatus that improves a recognition rate and operates at a low current is provided. The apparatus includes a first coil disposed between a first power supply source and a second power supply source, and wound in a first direction, a second coil connected in parallel to the first coil, disposed between the first power supply source and the second power supply source, and wound in a second direction, a first driver disposed between the first coil and the second power supply source, and configured to control a first current of the first coil according to a first voltage pulse supplied by a first pulse supply source, and a second driver disposed between the second coil and the second power supply source, and configured to control a second current of the second coil according to a second voltage pulse supplied by a second pulse supply source.
