MagneticStripeReaderErrorOccured

This event occurs when there is a magnetic stripe reader (MSR) error, such as a scanning error.

Syntax

typedef struct _MSR_ERROR_EVENT
{
    PosEventDataHeader Header;
    MsrTrackErrorType Track1Status;
    MsrTrackErrorType Track2Status;
    MsrTrackErrorType Track3Status;
    MsrTrackErrorType Track4Status;
    UnifiedPosErrorSeverity Severity;
    UnifiedPosErrorReason Reason;
    UINT32 ExtendedReason;
    MSR_DATA_RECEIVED CardData;
    wchar_t Message[MSR_ERROR_MAX_MESSAGE_LENGTH];
} MSR_ERROR_EVENT, *PMSR_ERROR_EVENT;
