8. Smart Card Commands
The commands executed by the BioCARDKey/BioSIMKey smart card reader can generally be divided into
two categories, namely, Control Commands and Card Commands.
Control Commands control the internal operation of the BioCARDKey/BioSIMKey. They do not directly affect
the card inserted in the reader and are therefore independent of the selected card type.
Card Commands are directed toward the card inserted in the BioCARDKey/BioSIMKey. The structure of
these commands and the data transmitted in the commands and responses depend on the selected card
type.
8.1 Control Commands
8.1.1 GET_ACR_STAT
This command returns relevant information about the particular BioCARDKey/BioSIMKey model and the
current operating status, such as, the firmware revision number, the maximum data length of a command
and response, the supported card types, and whether a card is inserted and powered up.

C_TYPE The card types supported by the BioCARDKey/BioSIMKey. This data field is a bitmap with each
bit representing a particular card type. A bit set to '1' means the corresponding card type is
supported by the reader and can be selected with the SELECT_CARD_TYPE command. The
bit assignment is as follows:
