摘要： A device and method for identifying critical card commands and their execution on the chip card. Each card command to be executed is supplied prior to its execution to a comparison device, which can either be a component of the chip card reader or a component independent of this. The comparison device checks with reference to filed comparison samples whether a critical card command is involved. A special comparison process is used for this. If the card command to be executed is a critical card command, it must be additionally confirmed by the user for it to be executed. A particular form of execution consists in comparison samples for identifying critical card commands being deposited during manufacture of the chip card and these being loaded into the working memory of the chip card reader or the comparison device on initialisation of the chip card in the chip card reader.
