This handles card insertion/removal events, updates ATR, protocol, and status information.
#define SCARD_E_INVALID_HANDLE
The supplied handle was invalid.
#define SCARD_F_INTERNAL_ERROR
An internal consistency check failed.
#define SCARD_W_RESET_CARD
The smart card has been reset, so any shared state information is invalid.

The Smart card resource manager has shut down.
#define SCARD_E_CANCELLED
The action was cancelled by an SCardCancel request.
#define SCARD_S_SUCCESS
No error was encountered.
#define SCARD_E_NO_MEMORY
Not enough memory available to complete this command.
#define SCARD_E_INVALID_VALUE
One or more of the supplied parameters values could not be properly interpreted.
#define SCARD_W_REMOVED_CARD
The smart card has been removed, so further communication is not possible.
