<p>PURPOSE:To obtain security against the falsification of data and the forgery of a magnetic card by providing a part where magnetic data is recorded on a magnetic recording medium by magnetic printing, and a part where the magnetic data is recorded by magnetic recording. CONSTITUTION:A magnetic printing part 2 is provided at the magnetic card 01 other than an ordinary magnetic recording part 1, and ID data different at every card is printed on the magnetic printing part 2, and also, required data with ID data coded with the ID data is written on the magnetic recording part 1, then, the card 01 is issued. Also, a magnetic card reader is comprised in such a way that the card is not accepted when no coding between the ID data of the magnetic printing part 2 and that of the magnetic recording part 1 is acquired.
