PROBLEM TO BE SOLVED: To reduce a processing load for read/write operation of a processor for processing magnetic stripe data. SOLUTION: A magnetic card control part 4 extracts magnetic stripe data of the field according to a field definition file 3 from the magnetic stripe data read by a card reader writer 1, and transfers the extracted magnetic stripe data to a processor 2, and replaces the field according to the definition in the magnetic stripe data read by the card reader writer 1 with a part of magnetic stripe data transferred from the processor 2, and writes this replaced magnetic stripe data in the magnetic stripe. |
