Card and device for processing of same

摘要

A hybrid card and a processing device capable of rapidly identifying a read/write unit corresponding to an IC module from a plurality of read/write units and preventing fraud in respect of the IC module. Identification data identifying the type of an IC module 11a is held in for example a magnetic stripe 11b outside the IC module 11a of a hybrid card 11. Authentication data corresponding to the identification data is held in the IC module 11a. An R/W unit adapted to the IC module 11a is selected in accordance with the identification data read from the location outside the IC module 11a. The identification data read from the location outside the IC module 11a and the authentication data contained in the data read from the IC module 11a are compared and, only if the two agree, the reading from or writing into the an IC read/write unit 130 is permitted.
