REMOVABLY CONNECTED DATA CARRIERS MADE OF DIFFERENT MATERIALS AND READABLE BY RESPECTIVE DIFFERENT READER TYPES

摘要

A system comprises a first data carrier (MOD) and a second data carrier (CDC). The first data carrier (MOD) is inserted in the second data carrier (CDC). The system is characterized in that, the first data carrier (MOD) is removable from the second data carrier (CDC), in that the first data carrier (MOD) is readable by a first reading machine, and in that the second data carrier (CDC) is readable by a second reading machine, which is different than the first reading machine.
