4 MTSCRAEvent
If you are using the Java library, after calling the functions in section 3 MTSCRA Functions , the
MTSCRA Windows SDK libraries for Java will invoke the callback functions in this section to provide
the requested data and/or a detailed response. Custom software that uses the MTSCRA libraries for Java
should create an object that implements the following functions to process the returning data, then register
it as a listener using the
init function. For sample code that demonstrates how to use these functions, see
SwipeReaderControlPanel.java
in the SDK files.
If you are using the Java applet, after calling the functions in section 3
MTSCRA Functions , the
MTSCRA Java applet will invoke the callback functions in this chapter to provide the requested data
and/or a detailed response. Custom code that uses the MTSCRA Java applet should implement the
following JavaScript functions to process the returning data. For sample code that demonstrates how to
use these functions, see the
mtjmsr.htm
and
mtjmsr.js
sample code in the SDK files.
