MAGNETIC CARD READER AND MAGNETIC CARD READING METHOD

摘要

A magnetic card reader equipped with: a magnetic card insertion slot; a magnetic noise generation unit that is provided near the magnetic card insertion slot; at least one magnetic head, said magnetic head having multiple magnetic reading components, that reads a first signal that contains magnetic noise from the magnetic noise generation unit and a signal recorded in a magnetic body of the magnetic card in a superimposed manner, and a second signal that contains only the magnetic noise generated by the magnetic noise generation unit; and a data processing unit that removes the second signal from the first signal.
