8.2. By Programmatic Method
The card type can also be changed the program run-time using Vendor Specific extension API of
PC/SC.
Application programs are required to include the following MACRO in one of the source header file:
#define IOCTL_SMARTCARD_SET_CARD_TYPE SCARD_CTL_CODE(2060)
Applications should connect to PC/SC using the SCARD_SHARE_DIRECT protocol. After which,
invoke the SCardControl() and use IOCTL_SMARTCARD_SET_CARD_TYPE for the dwControlCode
parameter to inform the driver of new card type. The input buffer will be a LONG variable storing the
desired card type. The return value is either SCARD_S_SUCCESS or a WIN32 Error
(ERROR_INSUFFICIENT_BUFFER).
