    Abstract: A magnetic stripe card reader useful for reading magnetic stripe bearing cards having at least one magnetic track, the magnetic stripe reader including a magnetic stripe reader head including multiple magnetic sensors including at least one magnetic track reading sensor for reading data encoded in a magnetic track of a magnetic stripe and at least one magnetic sensor which does not read encoded data, the magnetic stripe reader head providing magnetic sensor outputs including at least one magnetic track sensor reading output and at least one magnetic sensor output which has no encoded data therein and a subtractor operative to subtract at least a portion of the at least one magnetic sensor output, which has no encoded data therein, from the at least one magnetic track sensor reading output having card data encoded thereon, thereby to cancel interference from the at least one magnetic track reading output.
