Detailed Description

The SCardReader object is used to monitor one PC/SC reader (i.e. wait for card events)

Member Function Documentation

GetChannel()

SCardChannel SpringCard.PCSC.SCardReader.GetChannel

(

)

Create a SCardChannel object from this reader.

StatusChangeCallback()

delegate void SpringCard.PCSC.SCardReader.StatusChangeCallback	(	uint	ReaderState,
		CardBuffer	CardAtr
	)

Definition of the callback that will be called by the background thread launched by StartMonitor() everytime the status of the reader is changed.

Warning

The callback is invoked in the context of a background thread. This implies that it is not allowed to access the GUI's components directly.
